SAFETY PRECAUTIONS

RESIST RUSHING IN!

APPROACH CAUTIOUSLY FROM UPWIND, UPHILL AND/OR UPSTREAM:

• Stay clear of Vapor, Fumes, Smoke and Spills.

• Keep vehicle at a safe distance from the scene.

SECURE THE SCENE: 

• Isolate the area and protect yourself and others.

IDENTIFY THE HAZARDS USING ANY OF THE FOLLOWING:

• Placards

• Container labels

• Shipping papers

• Rail Car and Road Trailer Identification Chart

• Safety Data Sheets (SDS)

• Knowledge of persons on scene

• Consult applicable orange guide

ASSESS THE SITUATION:

• Is there a fire, a spill or a leak?

• What are the weather conditions?

• What is the terrain like?

• Who/what is at risk: people, property or the environment?

• What actions should be taken – evacuation, shelter-in-place or dike?

• What resources (human and equipment) are required?

• What can be done immediately?

OBTAIN HELP:

• Advise your headquarters to notify responsible agencies and call for assistance from 

qualified personnel.

RESPOND:

• Enter only when wearing appropriate protective gear. 

• Rescue attempts and protecting property must be weighed against you becoming 

part of the problem.

• Establish a command post and lines of communication.

• Continually reassess the situation and modify response accordingly.

• Consider safety of people in the immediate area first, including your own safety.

ABOVE ALL: Do not assume that gases or vapors are harmless because of lack of a 

smell – odorless gases or vapors may be harmful. Use CAUTION when handling empty 

containers because they may still present hazards until they are cleaned and purged of 

all residues.
Page 5

NOTIFICATION AND REQUEST FOR TECHNICAL INFORMATION

Follow the steps outlined in your organization’s standard operating procedures and/or local 

emergency response plan for obtaining qualified assistance. Generally, the notification 

sequence and requests for technical information beyond what is available in this guidebook 

should occur in the following order:

1. NOTIFY YOUR ORGANIZATION/AGENCY

• Based on information provided, this will set in motion a series of events. Actions 

may range from dispatching additional trained personnel to the scene, to 

activating the local emergency response plan. 

• Ensure that local fire and police departments have been notified.

2. CALL THE EMERGENCY RESPONSE TELEPHONE NUMBER ON THE 

SHIPPING PAPER

• If shipping paper is not available, use guidance under next section “NATIONAL 

ASSISTANCE”.

3. NATIONAL ASSISTANCE

• Contact the appropriate emergency response agency listed on the inside back cover 

of this guidebook.

• Provide as much information about the hazardous material/dangerous good and 

the nature of the incident.

• The agency will provide immediate advice on handling the early stages of the incident.

• The agency will also contact the shipper or manufacturer of the material for more 

detailed information if necessary.

• The agency will request on-scene assistance when necessary.

4. PROVIDE AS MUCH OF THE FOLLOWING INFORMATION AS POSSIBLE:

• Your name, call-back telephone number, fax number

• Location and nature of problem (spill, fire, etc.)

• Name and identification number of material(s) involved

• Shipper/consignee/point-of-origin

• Carrier name, rail car or truck number

• Container type and size

• Quantity of material transported/released

• Local conditions (weather, terrain)

• Proximity to schools, hospitals, waterways, etc.

• Injuries and exposures

• Local emergency services that have been notified

HAZARD CLASSIFICATION SYSTEM

The hazard class of hazardous materials/dangerous goods is indicated either by its class (or 

division) number or name. Placards are used to identify the class or division of a material. 

The hazard class or division number must be displayed in the lower corner of a placard and 

is required for both primary and subsidiary hazard classes and divisions, if applicable. For 

other than Class 7 placards, text indicating a hazard (for example, "CORROSIVE") is not 

required. Text is shown only in the U.S. The hazard class or division number and subsidiary 

hazard classes or division numbers placed in parentheses (when applicable), must appear 

on the shipping paper after each proper shipping name.

Class 1 - Explosives

Division 1.1 Explosives which have a mass explosion hazard

Division 1.2 Explosives which have a projection hazard but not a mass 

explosion hazard

Division 1.3 Explosives which have a fire hazard and either a minor blast 

hazard or a minor projection hazard or both, but not a mass 

explosion hazard

Division 1.4 Explosives which present no significant hazard

Division 1.5 Very insensitive explosives with a mass explosion hazard

Division 1.6 Extremely insensitive articles which do not have a mass 

explosion hazard

Class 2 - Gases

Division 2.1 Flammable gases

Division 2.2 Non-flammable, non-toxic* gases

Division 2.3 Toxic* gases

Class 3 - Flammable liquids (and Combustible liquids [U.S.])

Class 4 - Flammable solids; Substances liable to spontaneous combustion; 

Substances which, on contact with water, emit flammable gases

Division 4.1 Flammable solids, self-reactive substances and solid 

desensitized explosives

Division 4.2 Substances liable to spontaneous combustion

Division 4.3 Substances which in contact with water emit flammable gases

Class 5 - Oxidizing substances and Organic peroxides

Division 5.1 Oxidizing substances

Division 5.2 Organic peroxides

Class 6 - Toxic* substances and Infectious substances

Division 6.1 Toxic* substances

Division 6.2 Infectious substances

Class 7 - Radioactive materials

Class 8 - Corrosive substances

Class 9 - Miscellaneous hazardous materials/dangerous goods and articles 

* The words “poison” or “poisonous” are synonymous with the word “toxic”.

INTRODUCTION TO THE TABLE OF MARKINGS, LABELS AND PLACARDS

USE THIS TABLE ONLY WHEN THE ID NUMBER OR PROPER SHIPPING NAME IS 

NOT AVAILABLE.

This section displays the placards used on transport vehicles carrying hazardous materials/

dangerous goods with the applicable reference GUIDE circled. Follow these steps:

1. Approach scene from upwind, uphill and/or upstream at a safe distance to safely 

identify and/or read the placard or orange panel. Use binoculars if available.

2. Match the vehicle placard(s) with one of the placards displayed in this section.

3. Consult the circled guide number associated with the placard. Use that guide 

information for now. For example:

• Use GUIDE 127 for a FLAMMABLE (Class 3) placard 

• Use GUIDE 153 for a CORROSIVE (Class 8) placard 

• UseGUIDE 111 when the DANGER or DANGEROUS placard is displayed or the

nature of the spilled, leaking or burning material is not known. Also use this GUIDE 

when the presence of hazardous materials/dangerous goods is suspected but no 

placards can be seen. 

If multiple placards point to more than one guide, initially use the most conservative 

guide (i.e., the guide requiring the greatest degree of protective actions).

4. Guides associated with the placards provide the most significant risk and/or 

hazard information.

5. When specific information, such as ID number or proper shipping name, becomes 

available, the more specific Guide recommended for that material must be 

consulted.

6. A single asterisk (*) on orange placards represents an explosive's compatibility 

group letter. The asterisk must be replaced with the appropriate compatibility 

group letter. Refer to the “Glossary” section.

7. Double asterisks (**) on orange placards represent the division of the explosive. 

The double asterisks must be replaced with the appropriate division number.

RAIL CAR IDENTIFICATION CHART

CAUTION: Emergency response personnel must be aware that rail tank cars vary widely in 

construction, fittings and purpose. Tank cars could transport products that may be solids, 

liquids or gases. The products may be under pressure. It is essential that products be 

identified by consulting shipping papers or train consist or contacting dispatch centers before 

emergency response is initiated. The information stenciled on the sides or ends of tank cars, 

as illustrated below, may be used to identify the product utilizing:

a. the commodity name shown;

b. the other information shown, especially reporting marks and car number which, when 

supplied to a dispatch center, will facilitate the identification of the product.

The recommended guides should be considered as last resort if the material cannot 

be identified by any other means.

ROAD TRAILER IDENTIFICATION CHART

CAUTION: This chart depicts only the most general shapes of road trailers and cargo transport 

units. Emergency response personnel must be aware that there are many variations of road 

trailers, not illustrated below, that are used for shipping chemical products. Many intermodal 

tanks that transport liquids, solids, liquefied compressed gases, and refrigerated liquefied 

gases have similar silhouettes. The suggested guides are for the most hazardous products 

that may be transported in these trailer types.

 WARNING: Road trailers may be jacketed, the cross-section may look different than shown 

and external ring stiffeners would be invisible.

NOTE: An emergency shut-off valve is commonly found at the front of the tank, near the driver door.

The recommended guides should be considered as last resort if the material cannot 

be identified by any other means.

GLOBALLY HARMONIZED SYSTEM OF CLASSIFICATION 

AND LABELING OF CHEMICALS (GHS)

(May be found on means of containment during transport)

The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) is an 

international guideline published by the United Nations. The GHS aims to harmonize the 

classification and labeling systems for all sectors involved in the life cycle of a chemical 

(production, storage, transport, workplace use, consumer use and presence in the 

environment).

The GHS has nine symbols used to convey specific physical, health and environmental 

hazard information. These symbols are part of a pictogram that is diamond shaped and 

includes the GHS symbol in black on a white background with a red frame. The pictogram 

is part of the GHS label, which also includes the following information:

• Signal word

• Hazard statement

• Precautionary statements

• Product identifier

• Supplier identification

GHS pictograms are similar in shape to transport labels; however, transport labels have 

backgrounds of different colors.

The elements of the GHS that address signal words and hazard statements are not 

expected to be adopted in the transport sector. For substances and mixtures covered by 

the UN Recommendations on the Transport of Dangerous Goods, Model Regulations, the 

transport labels for physical hazards will have precedence. In transport, a GHS pictogram 

for the same (or lesser) hazard as the one reflected by the transport label or placard should 

not be present, but it could exist on the package.

Examples of GHS labeling: 

Outer Packaging: Box with 

flammable liquid transport label

Inner Packaging: Plastic 

bottle with GHS hazard 

warning label

Single Packaging: 200 L 

(55 US gallons) drum with 

a flammable liquid transport 

label combined with GHS 

hazard warning label
Page 17

In some cases, such as on drums or intermediate bulk containers (IBCs), which must 

address information for all sectors, the GHS label may be found in addition to the required 

transport labels and placards. Both types of labels (GHS and transport) will differ in a way 

that will make them easy to identify during an emergency.

Hazard identification numbers, utilized under European and some South American regulations, 

may be found in the top half of an orange panel on some intermodal bulk containers. 

The 4-digit ID number is in the bottom half of the orange panel.

The hazard identification number in the top half of the orange panel consists of two or 

three digits. In general, the digits indicate the following hazards:

2 - Emission of gas due to pressure or to chemical reaction

3 - Flammability of liquids (vapors) and gases or self-heating liquid

4 - Flammability of solids or self-heating solid

5 - Oxidizing (fire-intensifying) effect

6 - Toxicity or risk of infection

7 - Radioactivity

8 - Corrosivity

9 - Risk of spontaneous violent reaction

NOTE: The risk of spontaneous violent reaction within the meaning of digit 9 includes the 

possibility, due to the nature of a substance, of a risk of explosion, disintegration 

and polymerization reaction followed by the release of considerable heat or 

flammable and/or toxic gases. 

• Doubling of a digit indicates an intensification of that particular hazard (e.g., 33, 

66, 88).

• Where the hazard associated with a substance can be adequately indicated by a 

single digit, the digit is followed by a zero (e.g., 30, 40, 50).

• A hazard identification number prefixed by the letter “X” indicates that the 

substance will react dangerously with water (e.g., X88).

• For the transport of Class 1 materials, the hazard identification number will be 

replaced by the explosive’s division number and compatibility group.

PIPELINE TRANSPORTATION

In North America, hazardous materials/dangerous goods are commonly transported through 

millions of miles of pipelines and related structures. Products transported include natural gas, 

natural gas liquids, crude oil, gasoline, diesel fuel, anhydrous ammonia, carbon dioxide, jet 

fuel, and other commodities. Although most pipelines are buried, often there are above-ground 

structures and markers indicating the presence of pipelines. First responders should be 

aware of the pipelines in their jurisdictions, the products they transport, and the operators 

responsible for those pipelines. Proactive relationships can be beneficial in the safe and 

effective management of pipeline emergencies.

Types of Pipelines

Natural Gas Pipelines

Natural Gas Transmission Pipelines

Large-diameter, steel pipelines transport flammable natural gas (toxic and non-toxic) at 

very high pressures ranging from 200 to 1,500 psi*. Natural gas in transmission pipelines is 

odorless — generally not odorized with mercaptan (the “rotten egg” smell); however, natural 

gas containing hydrogen sulfide (H2S) will have a distinct “rotten egg” odor.

Natural Gas Distribution Pipelines

Natural gas is delivered directly to customers via distribution pipelines. These pipelines are 

typically smaller-diameter, lower-pressure pipelines constructed of steel, plastic, or cast iron. 

Natural gas in distribution pipelines is odorized with mercaptan (the “rotten egg” smell).

Natural Gas-Gathering and Natural Gas Well Production Pipelines

Natural gas-gathering/well production pipelines collect “raw” natural gas from wellheads and 

transport the product to gas-processing and/or gas-treating plants. These gathering pipelines 

carry natural gas mixed with some quantity of natural gas liquids, water, and, in some areas, 

contaminants such as toxic hydrogen sulfide (H2S). Natural gas in these pipelines is not 

odorized with mercaptan (the “rotten egg” smell); however, natural gas that contains hydrogen 

sulfide (H2S) will have a distinct “rotten egg” odor.

Hazardous Liquid and Highly Volatile Liquid Pipelines

Hazardous Liquid Pipelines

Crude oil, refined petroleum products (e.g. gasoline, kerosene, jet fuel or diesel) and hazardous 

liquids (e.g. anhydrous ammonia or ethanol) are often transported by pipelines. 

Many liquid petroleum pipelines transport different types of liquid petroleum in the same 

pipeline. To do so, the pipeline operator sends different products in “batches.” For example, 

an operator could send gasoline for several hours, and then switch to jet fuels, before 

switching to diesel fuel.

Page 23

Highly Volatile Liquid (HVL) Pipelines

HVL pipelines transport hazardous liquids which will form a vapor cloud when released to 

the atmosphere and which have a vapor pressure exceeding 276 KPa (40 psia) at 37.8°C 

(100°F). An example of an HVL is liquid propane.

Pipeline Markers

Since pipelines are usually buried underground, pipeline markers are used to indicate their 

presence in an area along the pipeline route. Of the three types of pipelines typically buried 

underground — distribution, gathering, and transmission — only transmission pipelines are 

marked with the following above-ground markers used to indicate their route.

Markers warn that a transmission pipeline is located in the area, identify the product 

transported in the line, and provide the name and telephone number of the pipeline operator 

to call. Markers and warning signs are located at frequent intervals along natural gas and 

liquid transmission pipeline rights-of-way, and are located at prominent points such as where 

pipelines intersect streets, highways, railways, or waterways.

Pipeline markers only indicate the presence of a pipeline—they do not indicate the exact 

location of the pipeline. Pipeline locations within a right-of-way may vary along its length and 

there may be multiple pipelines located in the same right-of-way.

NOTE: 

• Markers for pipelines transporting materials containing dangerous levels of hydrogen 

sulfide (H2S) may have markers that say: “Sour” or “Poison.”

• Natural gas distribution pipelines are not marked with above-ground signs.

• Gathering/production pipelines are often not marked with above-ground signs.

Indications of Pipeline Leaks and Ruptures

Pipeline releases can range from relatively minor leaks to catastrophic ruptures. It is important 

to remember that gases and liquids behave differently once they are released from a pipeline. 

Generally, the following could be indications of a pipeline leak or rupture:

• Hissing, roaring, or explosive sound

• Flames appearing from the ground or water (perhaps very large flames)

• Vapor cloud/fog/mist

• Dirt/debris/water blowing out of the ground

• Liquids bubbling up from the ground or bubbling in water

• Distinctive, unusually strong odor of rotten eggs, mercaptan (an odorant in some 

natural gas pipelines), skunk, or petroleum

• Discolored/dead vegetation or discolored snow above a pipeline right-of-way

• Oil slick or sheen on flowing/standing water

• An area of frozen ground in the summer

• An unusual area of melted snow in the winter
Page 25

General Considerations for Responding to a Pipeline Emergency

• Safety First! Your safety and the safety of the community you protect is top priority. 

Remember to approach a pipeline incident from upwind, uphill, and upstream while using 

air monitoring equipment to detect for the presence of explosive and/or toxic levels of 

hazardous materials/dangerous goods.

– Always wear proper personal protective equipment. Be prepared for a flash fire. Use 

shielding to protect first responders in the event of an explosion. Use respiratory 

protection.

– Never operate pipeline valves (except in coordination with the pipeline operator); 

this could make the incident worse and put you and others in danger.

– Never attempt to extinguish a pipeline fire before supply is shut off; this could result 

in the accumulation of a large flammable/explosive vapor cloud or liquid pool that 

could make the incident worse and put you and others in danger.

– Do not walk or drive into a vapor cloud in an attempt to identify the product(s) 

involved.

– Do not park over manholes or storm drains.

– Do not approach the scene with vehicles or mechanical equipment until the isolation 

zones have been established (vehicles are a potential ignition source).

• Secure the site and determine a plan to evacuate or shelter-in-place. Work with other 

responders to deny entry to an area.

• Identify the product and the operator. If safe to do so, you may be able to identify the 

product based on its characteristics or other external clues. Look for pipeline markers 

indicating the product, operator of the pipeline, and their emergency contact information. 

Pipelines transport many different types of products, including gases, liquids, and highly 

volatile liquids that are in a liquid state inside the pipeline but in a gaseous state if 

released from the pipeline. The vapor density of gases determines if they rise or sink in 

air. Viscosity and specific gravity also are important characteristics of hazardous liquids 

to consider. Identification of the product also will help you determine the appropriate 

distance for isolation of the affected area.

• Notify the pipeline operator using the emergency contact information on the pipeline 

marker or other contact information you may have received from the pipeline operator. 

The pipeline operator will be a resource to you in the response.

• Establish a command post. Implement the Incident Command Structure, as needed, 

and be prepared to implement a Unified Command as additional stakeholders and 

resources arrive.
Page 26

Other Important Considerations

• If no flames are present, do not introduce ignition sources such as open flames, running 

vehicles, or electrical equipment (cell phones, pagers, two-way radios, lights, garage 

door openers, fans, door bells, etc.).

• Abandon any equipment used in or near the area of the pipeline release.

• If there is no risk to your safety or the safety of others, move far enough away from any 

noise coming from the pipeline to allow for normal conversation.

• Pipelines often are close to other public utilities, railroads, and highways; these can be 

impacted by pipeline releases or may be potential ignition sources.

• Natural gas can migrate underground from the source of a release to other areas via the 

path of least resistance (including through sewers, water lines, and geologic formations).

Considerations for Establishing Protective Action Distances

• Type of product

– If you know the material involved, identify the three-digit guide number by looking 

up the name in the alphabetical list (blue section). The relevant guide will provide 

an idea of the risks posed by the material.

• Pressure and diameter of pipe (the pipeline operator can tell you this if you don’t 

already know it)

• Timing of valve closure by the pipeline operator (quickly for automated valves; longer 

for manually operated valves)

• Dissipation time of the product in the pipeline once valves are closed

• Ability to conduct atmospheric monitoring and/or air sampling

• Weather (wind direction, etc.)

• Local variables such as topography, population density, demographics, and fire 

suppression methods available

• Nearby building construction material/density

• Natural and man-made barriers (such as highways, railroads, rivers, etc.)

U.S. Pipeline Resources

U.S. Pipeline Locations: The National Pipeline Mapping System (NPMS) 

https://www.npms.phmsa.dot.gov indicates the general locations of hazardous liquids and 

natural gas transmission pipelines found within the U.S. The pipelines depicted in the NPMS 

are within 500 feet of their actual locations. Emergency responders may apply for an NPMS 

web viewer account that will allow access to more detailed information than is available to the 

general public. The NPMS does not contain gathering/production or natural gas distribution 

pipelines.

U.S. Pipeline Emergency Response Training: Where appropriate, reference pipeline 

emergencies training materials produced by the Pipeline and Hazardous Materials Safety 

Administration. Your state or jurisdiction also may provide training on how to handle the 

response to a pipeline incident.

INTRODUCTION TO YELLOW SECTION

For entries highlighted in green follow these steps:

• IF THERE IS NO FIRE:

- Go directly to Table 1 (green section)

- Look up the ID number and name of material

- Identify initial isolation and protective action distances

- Also consult the appropriate Orange Guide

• IF A FIRE IS INVOLVED:

- Use the appropriate Orange Guide for EVACUATION distances

- Also protect in downwind direction according to Table 1 for residual 

material release

Note 1: If the name in Table 1 is shown with (when spilled in water), these materials 

produce large amounts of Toxic Inhalation Hazard (TIH) (PIH in the US) gases 

when spilled in water. Some water-reactive materials are also TIH materials 

themselves (e.g., UN1746 (Bromine trifluoride), UN1836 (Thionyl chloride)). In 

these instances, two entries are provided in Table 1 for land-based and waterbased spills. If a water-reactive material only has one entry in Table 1 for (when 

spilled in water) and the product is NOT spilled in water, Table 1 and Table 2 

do not apply. You will find safe distances in the appropriate Orange Guide.

Note 2: Explosives are not individually listed by their ID number because in an emergency 

situation, the response will be based only on the division of the explosive, not on 

the individual explosive.

For divisions 1.1, 1.2, 1.3 and 1.5, refer to GUIDE 112.

For divisions 1.4 and 1.6, refer to GUIDE 114.

Note 3: Chemical and biological warfare agents are now found in the “Criminal or Terrorist 

Use of Chemical, Biological and Radiological Agents” section.

INTRODUCTION TO BLUE SECTION

For entries highlighted in green follow these steps:

• IF THERE IS NO FIRE:

- Go directly to Table 1 (green section)

- Look up the ID number and name of material

- Identify initial isolation and protective action distances

- Also consult the appropriate Orange Guide

• IF A FIRE IS INVOLVED:

- Use the appropriate Orange Guide for EVACUATION distances

- Also protect in downwind direction according to Table 1 for residual 

material release

Note 1: If the name in Table 1 is shown with (when spilled in water), these materials produce 

large amounts of Toxic Inhalation Hazard (TIH) (PIH in the US) gases when spilled in 

water. Some water-reactive materials are also TIH materials themselves (e.g., UN1746 

(Bromine trifluoride), UN1836 (Thionyl chloride)). In these instances, two entries are 

provided in Table 1 for land-based and water-based spills. If a water-reactive material 

only has one entry in Table 1 for (when spilled in water) and the product is NOT 

spilled in water, Table 1 and Table 2 do not apply. You will find safe distances in the 

appropriate Orange Guide.

Note 2: Explosives are not individually listed by their name because in an emergency situation, 

the response will be based only on the division of the explosive, not on the individual 

explosive.

For divisions 1.1, 1.2, 1.3 and 1.5, refer to GUIDE 112.

For divisions 1.4 and 1.6, refer to GUIDE 114.

Note 3: Chemical and biological warfare agents are now found in the “Criminal or Terrorist 

Use of Chemical, Biological and Radiological Agents” section.

117 POTENTIAL HAZARDS

HEALTH

• TOXIC; Extremely Hazardous.

• May be fatal if inhaled or absorbed through skin.

• Initial odor may be irritating or foul and may deaden your sense of smell.

• Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite.

• Fire will produce irritating, corrosive and/or toxic gases.

• Runoff from fire control or dilution water may cause environmental contamination.

FIRE OR EXPLOSION

• These materials are extremely flammable.

• May form explosive mixtures with air.

• May be ignited by heat, sparks or flames.

• Vapors from liquefied gas are initially heavier than air and spread along ground.

• Vapors may travel to source of ignition and flash back.

• Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. 

• Runoff may create fire or explosion hazard.

• Cylinders exposed to fire may vent and release toxic and flammable gas through pressure relief devices.

• Containers may explode when heated.

• Ruptured cylinders may rocket.

PUBLIC SAFETY

• CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper 

not available or no answer, refer to appropriate telephone number listed on the inside back cover.

• Keep unauthorized personnel away.

• Stay upwind, uphill and/or upstream.

• Many gases are heavier than air and will spread along the ground and collect in low or confined areas 

(sewers, basements, tanks, etc.).

• Ventilate closed spaces before entering, but only if properly trained and equipped.

PROTECTIVE CLOTHING

• Wear positive pressure self-contained breathing apparatus (SCBA).

• Wear chemical protective clothing that is specifically recommended by the manufacturer when there is 

NO RISK OF FIRE.

• Structural firefighters' protective clothing provides thermal protection but only limited chemical protection.

EVACUATION

Immediate precautionary measure

• Isolate spill or leak area for at least 100 meters (330 feet) in all directions. 

Spill

• See Table 1 - Initial Isolation and Protective Action Distances.

Fire

• If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 1600 meters (1 mile) in all 

directions; also, consider initial evacuation for 1600 meters (1 mile) in all directions.

Gases - Toxic - Flammable

(Extreme Hazard)

EMERGENCY RESPONSE

FIRE

• DO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE STOPPED.

Small Fire

• Dry chemical, CO2, water spray or regular foam.

Large Fire

• Water spray, fog or regular foam.

• If it can be done safely, move undamaged containers away from the area around the fire.

• Damaged cylinders should be handled only by specialists.

Fire Involving Tanks

• Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles.

• Cool containers with flooding quantities of water until well after fire is out.

• Do not direct water at source of leak or safety devices; icing may occur.

• Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.

• ALWAYS stay away from tanks in direct contact with flames.

SPILL OR LEAK

• ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

• All equipment used when handling the product must be grounded.

• Do not touch or walk through spilled material.

• Stop leak if you can do it without risk.

• Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled 

material.

• Do not direct water at spill or source of leak.

• If possible, turn leaking containers so that gas escapes rather than liquid.

• Prevent entry into waterways, sewers, basements or confined areas.

• Isolate area until gas has dispersed.

• Consider igniting spill or leak to eliminate toxic gas concerns.

FIRST AID

Refer to the “General First Aid” section.

Specific First Aid:

• In case of contact with liquefied gas, only medical personnel should attempt thawing frosted parts.

• In case of burns, immediately cool affected skin for as long as possible with cold water. Do not remove 

clothing if adhering to skin.

Gases - Toxic - Flammable

(Extreme Hazard)

In Canada, an Emergency Response Assistance Plan (ERAP) may be required for this product.

ERG 2024

 PUBLIC SAFETY 

• This section is divided into three subsections:

› General Information: describes initial precautionary measures to be taken 

by those first on the scene.

› PROTECTIVE CLOTHING: provides general guidance on personal 

protective equipment requirements including respiratory protection. The 

protective clothing information is general and correct selection is situation 

dependent, after considering the physical and chemical properties of the 

material, weather conditions, spill versus fire, topography, etc. 

› EVACUATION: suggests protective distances for immediate precautionary 

measures defined for small and large spills, including suggested guidance 

for conditions where fire is present or likely (potential fragmentation 

hazard).

− The term “isolate” indicates a zone of no entry that applies to the public 

and first responders who are not equipped, trained, and prepared to 

mitigate the incident.

− The term “evacuate” aims to protect as many people as possible by 

removing persons from inside a zone safely. If removal is too risky, 

sheltering-in-place can also be considered in this zone.

• Materials highlighted in green in the yellow and blue sections direct the reader 

to consult Table 1, detailing specific response distances for toxic inhalation 

hazard materials and water-reactive materials (green section).

EMERGENCY RESPONSE 

• This section is divided into three subsections: 

› FIRE: provides extinguishing procedures for Small Fire, Large Fire, and/

or Fire Involving Tanks or Car/Trailer Loads

› SPILL OR LEAK: includes general recommendations, and may describe 

the response procedure for Small Spill and Large Spill 

› FIRST AID: provides specific first aid guidance to use for a product or a 

guide in addition to the general first aid guidance for hazardous materials/

dangerous goods incidents. General first aid guidance is found in the 

“General First Aid” section situated immediately after the “How to use the 

Orange Guides” section.

If a Canadian flag appears in this section, and the incident is located in Canada, an 

Emergency Response Assistance Plan (ERAP) may be required for this product.

• Call 911 or emergency medical service.

• Ensure that medical personnel are aware of the material(s) involved, take precautions 

to protect themselves and avoid contamination.

• Move victim to fresh air if it can be done safely.

• Administer oxygen if breathing is difficult.

• If victim is not breathing:

– DO NOT perform mouth-to-mouth resuscitation; the victim may have ingested 

or inhaled the substance.

– If equipped and pulse detected, wash face and mouth, then give artificial 

respiration using a proper respiratory medical device (bag-valve mask, pocket 

mask equipped with a one-way valve or other device).

– If no pulse detected or no respiratory medical device available, provide continuous 

compressions. Conduct a pulse check every two minutes or monitor for any signs 

of spontaneous respirations.

• Remove and isolate contaminated clothing and shoes.

• For minor skin contact, avoid spreading material on unaffected skin.

• In case of contact with substance, remove immediately by flushing skin or eyes with 

running water for at least 20 minutes.

• For severe burns, immediate medical attention is required.

FIRE

CAUTION: The majority of these products have a very low flash point. Use of water spray when 

fighting fire may be inefficient.

CAUTION: For mixtures containing alcohol or polar solvent, alcohol-resistant foam may be more 

effective.

Small Fire

• Dry chemical, CO2, water spray or regular foam. If regular foam is ineffective or unavailable, 

use alcohol-resistant foam.

Large Fire

• Water spray, fog or regular foam. If regular foam is ineffective or unavailable, use alcohol-resistant foam.

• Avoid aiming straight or solid streams directly onto the product.

• If it can be done safely, move undamaged containers away from the area around the fire.

Fire Involving Tanks, Rail Tank Cars or Highway Tanks

• Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles.

• Cool containers with flooding quantities of water until well after fire is out.

• For petroleum crude oil, do not spray water directly into a breached tank car. This can lead to a 

dangerous boil over. 

• Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.

• ALWAYS stay away from tanks in direct contact with flames.

• For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, 

withdraw from area and let fire burn.

SPILL OR LEAK

• ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

• All equipment used when handling the product must be grounded.

• Do not touch or walk through spilled material.

• Stop leak if you can do it without risk.

• Prevent entry into waterways, sewers, basements or confined areas.

• A vapor-suppressing foam may be used to reduce vapors.

• Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers.

• Use clean, non-sparking tools to collect absorbed material.

Large Spill

• Dike far ahead of liquid spill for later disposal.

• Water spray may reduce vapor, but may not prevent ignition in closed spaces.

POTENTIAL HAZARDS

HEALTH

• Radiation presents minimal risk to transport workers, emergency response personnel and the public 

during transportation accidents. Packaging durability increases as potential hazard of radioactive content 

increases.

• Very low levels of contained radioactive materials and low radiation levels outside packages result in low 

risks to people. Damaged packages may release measurable amounts of radioactive material, but the 

resulting risks are expected to be low.

• Some radioactive materials cannot be detected by commonly available instruments.

• Packages do not have RADIOACTIVE I, II, or III labels. Some may have EMPTY labels or may have the 

word “Radioactive” in the package marking.

FIRE OR EXPLOSION

• Some of these materials may burn, but most do not ignite readily.

• Many have cardboard outer packaging; content (physically large or small) can be of many different 

physical forms.

• Radioactivity does not change flammability or other properties of materials.

PUBLIC SAFETY

• CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper 

not available or no answer, refer to appropriate telephone number listed on the inside back cover.

POTENTIAL HAZARDS

HEALTH

• Radiation presents minimal risk to transport workers, emergency response personnel and the public 

during transportation accidents. Packaging durability increases as potential hazard of radioactive content 

increases.

• Undamaged packages are safe. Contents of damaged packages may cause higher external radiation 

exposure, or both external and internal radiation exposure if contents are released.

• Low radiation hazard when material is inside container. If material is released from package or bulk 

container, hazard will vary from low to moderate. Level of hazard will depend on the type and amount of 

radioactivity, the kind of material it is in, and/or the surfaces it is on.

• Some material may be released from packages during accidents of moderate severity but risks to people 

are not great.

• Released radioactive materials or contaminated objects usually will be visible if packaging fails.

• Some exclusive use shipments of bulk and packaged materials will not have RADIOACTIVE labels. 

Placards, markings and shipping papers provide identification.

• Some packages may have a RADIOACTIVE label and a second hazard label. The second hazard is usually 

greater than the radiation hazard; so follow this GUIDE as well as the response GUIDE for the second 

hazard class label.

• Some radioactive materials cannot be detected by commonly available instruments.

• Runoff from control of cargo fire may cause low-level pollution.

FIRE OR EXPLOSION

• Some of these materials may burn, but most do not ignite readily.

• Uranium and Thorium metal cuttings may ignite spontaneously if exposed to air (see GUIDE 136).

• Nitrates are oxidizers and may ignite other combustibles (see GUIDE 141).

of design, evaluation and testing of packages, these conditions would be expected only for accidents of 

utmost severity.

• The rarely occurring "Special Arrangement" shipments may be of Type A, Type B or Type C packages. 

Package type will be marked on packages, and shipment details will be on shipping papers.

• Radioactive White-I labels indicate radiation levels outside single, isolated, undamaged packages are 

very low (less than 0.005 mSv/h (0.5 mrem/h)).

• Radioactive Yellow-II and Yellow-III labeled packages have higher radiation levels. The transport index 

(TI) on the label identifies the maximum radiation level in mrem/h one meter from a single, isolated, 

undamaged package.

transportation accidents. Packaging durability increases as potential hazard of radioactive content increases.

• Undamaged packages are safe. Contents of damaged packages may cause higher external radiation exposure, 

or both external and internal radiation exposure if contents are released.

• Type AF or IF packages, identified by package markings, do not contain life-threatening amounts of material. 

External radiation levels are low and packages are designed, evaluated and tested to control releases and to 

prevent a fission chain reaction under severe transport conditions.

• Type B(U)F, B(M)F and CF packages (identified by markings on packages or shipping papers) contain potentially 

life-endangering amounts. Because of design, evaluation and testing of packages, fission chain reactions are 

prevented and releases are not expected to be life-endangering for all accidents except those of utmost severity.

• The rarely occurring "Special Arrangement" shipments may be of Type AF, BF or CF packages. Package type 

will be marked on packages, and shipment details will be on shipping papers.

• The transport index (TI) shown on labels or a shipping paper might not indicate the radiation level at one meter 

from a single, isolated, undamaged package; instead, it might relate to controls needed during transport because 

of the fissile properties of the materials. Alternatively, the fissile nature of the contents is indicated by a criticality

INTRODUCTION TO GREEN TABLES

TABLE 1 - INITIAL ISOLATION AND PROTECTIVE ACTION DISTANCES

This table suggests distances useful to protect people from vapors/gases resulting from 

spills involving:

• materials that are considered toxic by inhalation (TIH) (PIH in the US)

• materials which produce toxic gases upon contact with water

This table provides first responders with initial guidance until technically qualified emergency 

response personnel are available. For each material, first responders will find distances for 

the following zones:

• The Initial Isolation Zone defines an area surrounding the incident in which 

people may be exposed to dangerous (upwind) and life-threatening (downwind) 

concentrations of material.

• The Protective Action Zone defines an area downwind from the incident in which 

people may become incapacitated and unable to take protective action and/or incur 

serious or irreversible health effects. Table 1 provides specific guidance for small 

and large spills occurring day or night.

Adjusting distances for a specific incident involves many interdependent variables. These 

adjustments should only be made by technically qualified personnel. For this reason, no 

precise guidance can be provided in this document to aid in adjusting the table distances; 

however, general guidance follows.

Factors that May Change the Protective Action Distances

Fire

In the orange section, under EVACUATION – Fire, the evacuation distance required to 

protect against fragmentation hazard of a large container is clearly indicated. If involved in a 

fire, the toxic hazard may be less dangerous than the fire or explosion hazard.

In these cases, the fire hazard distance should be used as an isolation distance and Table 

1 should be used to protect downwind for residual material release.

Worst-case scenario: terrorism, sabotage or catastrophic accident

Initial isolation and protective action distances are derived from historical data on 

transportation incidents and the use of statistical models. For worst-case scenarios involving 

the instantaneous release of the entire contents of a package (e.g., as a result of terrorism, 

sabotage or catastrophic accident), the distances may increase substantially.

For such events, doubling the initial isolation and protective action distances is appropriate 

in absence of other information.

When more than one large package is leaking

If more than one rail tank car, highway tank, tank or large cylinder, containing TIH materials 

is leaking, large spill distances may need to be increased.
Page 281

Other factors that can increase the protective action distance:

• If a material has a protective action distance of 11.0+ km (7.0+ miles), the actual 

distance can be larger in certain atmospheric conditions.

• If the material’s vapor plume is channeled in a valley or between many tall 

buildings, protective action distances may be larger than shown due to less mixing 

of the plume with the atmosphere.

• If there is a daytime spill in a region with known strong temperature inversions

or snow cover, or it occurs near sunset, this may require an increase of the 

protective action distance because airborne contaminants mix and disperse more 

slowly and may travel much farther downwind.

› In such cases, the nighttime protective action distances may be more 

appropriate.

• If the temperature of the liquid spill or the outdoor temperature exceeds 30°C 

(86°F), the protective action distance may be larger.

Water-reactive materials

Materials that react with water to produce large amounts of toxic gases are included in Table 

1. Some of these materials have 2 entries in Table 1. They are identified by (when spilled 

on land) since they are TIH products and (when spilled in water) because they produce 

additional toxic gases when spilled in water. 

Choose the larger protective action distance if:

• it is not clear whether the spill is on land or in water

• the spill occurs both on land and in water

TABLE 2 - WATER-REACTIVE MATERIALS WHICH PRODUCE TOXIC GASES

This table lists materials which produce large amounts of Toxic Inhalation Hazard gases 

(TIH) when spilled in water as well as the TIH gases that are produced.

NOTE: The produced TIH gases indicated in Table 2 are for information purposes only. 

In Table 1, the initial isolation and protective action distances have already taken into 

consideration the produced TIH gas.

When a water-reactive TIH-producing material is spilled into a river or stream, the source of 

the toxic gas may flow downstream for a great distance.
Page 282

TABLE 3 - INITIAL ISOLATION AND PROTECTIVE ACTION DISTANCES FOR LARGE 

SPILLS FOR DIFFERENT QUANTITIES OF SIX COMMON TIH (PIH IN THE US) GASES

This table lists materials that may be more commonly encountered. These materials are:

• UN1005 - Ammonia, anhydrous

• UN1017 - Chlorine

• UN1040 - Ethylene oxide and UN1040 - Ethylene oxide with nitrogen

• UN1050 - Hydrogen chloride, anhydrous and UN2186 - Hydrogen chloride, 

refrigerated liquid

• UN1052 - Hydrogen fluoride, anhydrous

• UN1079 - Sulfur dioxide/Sulphur dioxide

This table provides initial isolation and protective action distances for large spills (more than 

208 liters or 55 US gallons):

• involving different container types (therefore different volume capacities)

• for daytime and nighttime situations

• for different wind speeds (low, moderate and high)
Page 283

PROTECTIVE ACTIONS

Protective actions are the steps taken to preserve the health and safety of emergency 

responders and the public during an incident involving releases of hazardous materials/

dangerous goods.

Table 1 - Initial Isolation and Protective Action Distances (green section) predicts the size 

of the area that could be affected by a cloud of toxic gas. People in this area should be 

evacuated and/or sheltered-in-place inside buildings.

Isolate hazard area and deny entry means to keep everybody away from the area if they are 

not directly involved in emergency response operations. Unprotected emergency responders 

should not be allowed to enter the isolation zone.

This "isolation" task is done to establish control over the area of operations. This is the first 

step for any protective actions that may follow.

Evacuate means to move all people from a threatened area to a safer place. To perform an 

evacuation, there must be enough time for people to be warned, get ready, and leave an 

area. If there is enough time, evacuation is the best protective action.

Begin evacuating people nearby and those who are outdoors in direct view of the scene. 

When additional help arrives, expand the area to be evacuated downwind and crosswind to 

at least the extent recommended in this guidebook.

Even after people move to the distances recommended, they may not be completely safe 

from harm. They should not be permitted to gather at such distances. Send evacuees to a 

definite place, by a specific route, far enough away so they will not have to relocate again 

if the wind shifts.

Shelter-in-place means people should seek shelter inside a building and remain inside 

until the danger passes. It is vital for first responders to maintain communications with 

sheltered-in-place people so that they are advised about changing conditions. 

Sheltering-in-place is used either when:

• evacuating the public would cause greater risk than staying where they are

• an evacuation cannot be safely performed

Direct the people inside to:

• close all doors and windows

• shut off all ventilating, heating and cooling systems

• stay far from windows to avoid shattered glass and projectile metal fragments in 

the event of a fire and/or explosion

• seal cracks around doors, windows and vents with duct tape or wet cloths

• tune in to local media, and remain inside until told it is safe to leave by first 

responders or emergency response authorities

• breathe through a wet cloth until an all clear has been communicated

Vehicles can offer some protection for a short period if the windows are closed and the 

ventilation systems are shut off. Vehicles are not nearly as effective as buildings for in-place 

protection.

PROTECTIVE ACTION DECISION FACTORS TO CONSIDER

The choice of protective actions for a given situation depends on a number of factors. For 

some cases, evacuation may be the best option; in others, sheltering-in-place may be the 

best course. Sometimes, these two actions may be used in combination. In any emergency, 

officials need to quickly give the public instructions. The public will need continuing information 

and instructions while being evacuated or sheltered-in-place.

Proper evaluation of the factors listed below will determine the effectiveness of evacuation or 

in-place protection (shelter-in-place). The importance of these factors can vary with emergency 

conditions. In specific emergencies, other factors may need to be identified and considered as 

well. This list indicates what kind of information may be needed to make the initial decision.

The hazardous materials/dangerous goods:

• degree of health hazard

• chemical and physical properties

• amount involved

• containment/control of release

• rate of vapor movement

The population threatened:

• location

• number of people

• time available to evacuate or shelter-in-place

• ability to control evacuation or shelter-in-place

• building types and availability

• special institutions or populations, e.g., nursing homes, hospitals, prisons

The weather conditions:

• effect on vapor and cloud movement

• potential for change

• effect on evacuation or shelter-in-place

NOTE: Every hazardous materials/dangerous goods incident is different. Each will have 

special problems and concerns. Actions to protect the public must be carefully selected. 

This section can help with initial decisions on how to protect the public. Officials must 

continue to gather information and monitor the situation until the threat is removed.
Page 285

The following table can help to decide if evacuation or sheltering-in-place 

is the best option:

Consider Evacuation: Consider Sheltering-in-place:

Vapors are flammable. Vapors are toxic, and people are likely 

to be exposed by evacuating.

Buildings cannot be closed tightly. Buildings can be quickly sealed by 

closing all windows and ventilation 

systems, if applicable.

The vapors are continuously generated 

and will hug the ground, or it will take a 

long time for the vapors to clear the area.

The vapors will quickly rise in the air 

column or rapidly dissipate.

For anyone outdoors. For anyone already indoors.

There are few people to evacuate. There are too many people to evacuate 

for current available resources.

The threat seems stable but longlasting.Circumstances are changing too quickly 

to evacuate safely.

BACKGROUND ON TABLE 1 – INITIAL ISOLATION 

AND PROTECTIVE ACTION DISTANCES

Initial isolation and protective action distances in this guidebook were determined for small 

and large spills occurring during day or night. The overall analysis, statistical in nature, was 

conducted using:

• state-of-the-art emission rate and dispersion models

• statistical release data from the U.S. Department of Transportation (DOT) 

Hazardous Materials Information System (HMIS) database

• meteorological observations from more than 120 locations in the United States, 

Canada, and Mexico

• the most current toxicological exposure guidelines

For each chemical, thousands of hypothetical releases were modeled to account for the statistical 

variance in both release amount and atmospheric conditions. Based on this statistical sample, 

they selected the 90th percentile protective action distance for each chemical and category to 

appear in the table. A brief description of the analysis is provided below.

A detailed report outlining the methodology and data used to generate the initial isolation and 

protective action distances may be obtained from the U.S. DOT, Pipeline and Hazardous 

Materials Safety Administration (PHMSA).

DESCRIPTION OF THE ANALYSIS

Release amounts and emission rates into the atmosphere were statistically modeled 

based on:

• data from the U.S. DOT HMIS database

• container types and sizes authorized for transport as specified in 49 CFR §172.101 

and Part 173

• physical properties of the individual materials

• atmospheric data from a historical database

For liquefied gases, which can flash to form both a vapor/aerosol mixture and an evaporating 

pool, the emission model calculated one or both of:

• the release of vapor due to evaporation of pools on the ground

• direct release of vapors from the container 

The emission model also calculated the emission of toxic vapor by-products generated from 

spilling water-reactive materials in water.

Small spills involve 208 liters (55 US gallons) or less. 

Large spills involve greater quantities.
Page 287

Downwind dispersion of the vapor was estimated for each case modeled. Using a database 

containing hourly meteorological data from 120 American, Canadian, and Mexican cities, 

the atmospheric parameters affecting the dispersion and the emission rate were selected.

The dispersion calculation accounted for both the:

• time-dependent emission rate from the source

• density of the vapor plume (i.e., heavy gas effects)

Since atmospheric mixing is less effective at dispersing vapor plumes during nighttime, day 

and night were separated in the analysis.

In the table:

• day refers to time periods after sunrise and before sunset

• night includes all hours between sunset and sunrise

Toxicological short-term exposure guidelines for the materials were applied to determine 

the downwind distance to which people may:

• become incapacitated and unable to take protective action

• incur serious health effects after a single, or rare, exposure

When available, toxicological exposure guidelines were chosen from AEGL-2 or ERPG-2 

emergency response guidelines. AEGL-2 values were the first choice.

For materials without AEGL-2 or ERPG-2 values, emergency response guidelines were 

estimated based on lethal concentration limits derived from animal-based-studies. This 

approach was recommended by an independent panel of toxicological experts from industry 

and academia.

HOW TO USE TABLE 1 – INITIAL ISOLATION AND

PROTECTIVE ACTION DISTANCES

(1) The responder should already have:

• identified the material by its ID number and name (if you cannot find an ID number, 

use the Name of Material index in the blue section to find that number);

• confirmed that the material is highlighted in green in the yellow or blue section. If 

not, Table 1 doesn’t apply;

• found the three-digit guide for the material, in order to consult emergency actions 

it recommends along with this table; and

• noted the wind direction

(2) Look in Table 1 (green section) for the ID number and name of the material involved. 

Some ID numbers have more than one shipping name listed. Look for the specific name 

of the material. If you do not know the shipping name and Table 1 lists more than one 

name for the same ID number, use the entry with the largest distances.

(3) Determine if the incident involves a SMALL or LARGE spill and if it is DAY or NIGHT. 

A SMALL SPILL consists of a release of 208 liters (55 US gallons) or less. This generally 

corresponds to a spill from a single small package (for example, a drum), a small cylinder, 

or a small leak from a large package. A LARGE SPILL consists of a release of more than 

208 liters (55 US gallons). This usually involves a spill from a large package, or multiple 

spills from many small packages. DAY is any time after sunrise and before sunset. 

NIGHT is any time between sunset and sunrise. 

(4) Look up the INITIAL ISOLATION DISTANCE. 

This distance defines the radius of a zone (initial 

isolation zone) surrounding the spill in ALL 

DIRECTIONS. In this zone, protective clothing 

and respiratory protection is required. Evacuate 

the general public in a direction perpendicular 

to wind direction (crosswind) and away from 

the spill.

(5) Look up the PROTECTIVE ACTION DISTANCE. 

For a given material, spill size, and whether day or night, Table 1 gives the downwind 

distance—in kilometers and miles—from the spill or leak source, for which you should 

consider protective actions. For practical purposes, the protective action zone (i.e., 

the area in which people are at risk of harmful exposure) is a square. Its length and 

width are the same as the downwind distance shown in Table 1. Protective actions are 

the steps you take to preserve the health and safety of emergency responders and

the public. People in this area should be evacuated and/or sheltered-in-place. 

For more information, consult the “Protective Actions” section.

(6) Initiate protective actions beginning with those closest to the spill site and working 

away in a downwind direction. When a water-reactive TIH (PIH in the US) producing 

material is spilled into a river or stream, the source of the toxic gas may move with the 

current or stretch from the spill point downstream for a large distance.

In the figure below, the spill is located at the center of the small black circle. The larger 

circle represents the initial isolation zone around the spill. The square (the protective 

action zone) is the area in which you should take protective actions.

Note 1: For factors that may change the protective action distances, see the 

"Introduction to Green Tables" section.

Note 2: When a product in Table 1 has the mention (when spilled in water), you 

can refer to Table 2 for the list of gases produced when these materials 

are spilled in water. The TIH gases indicated in Table 2 are for information 

purposes only.

Note 3: For the instantaneous release of the entire contents of a package (e.g., as a 

result of terrorism, sabotage or catastrophic failure), the distances should 

be doubled.

For more information on the material, safety precautions and mitigation procedures, call 

the emergency response telephone number listed on the shipping paper or the appropriate 

response agency as soon as possible.

See Next Page for Table 2 - Water-Reactive Materials Which Produce Toxic Gases
Page 334

HOW TO USE TABLE 2 – WATER-REACTIVE MATERIALS

WHICH PRODUCE TOXIC GASES

Table 2 lists materials which produce large amounts of Toxic Inhalation Hazard (TIH) (PIH 

in the US) gases when spilled in water, and identifies the TIH gases produced.

The materials are listed by order of ID number.

These water-reactive materials are easily identified in Table 1 as their names are

immediately followed by (when spilled in water). 

Note 1: The TIH gases indicated in Table 2 are for information purposes only. In Table 

1, the initial isolation and protective action distances have already taken into 

consideration the TIH gases produced.

For example: Table 2 indicates that UN1689 sodium cyanide, when spilled 

in water, will generate hydrogen cyanide gas (HCN). In Table 1, you must 

refer to the distances for sodium cyanide and not the distances for hydrogen 

cyanide gas.

Note 2: Some water-reactive materials are also TIH materials themselves (e.g., UN1746 

(Bromine trifluoride), UN1836 (Thionyl chloride)). In these instances, two entries 

are provided in Table 1 for land-based and water-based spills. If a water-reactive 

material only has one entry in Table 1 for (when spilled in water), and the 

product is NOT spilled in water, Tables 1 and 2 do NOT apply. Refer only to the 

appropriate Orange Guide.

Note 3: Materials classified as a Division 4.3 are substances that, on contact with water, 

are liable to become spontaneously FLAMMABLE or give off FLAMMABLE or 

sometimes TOXIC gases in dangerous quantities. For the purpose of this table, 

water-reactive materials are materials that generate substantial quantities of 

TOXIC gases rapidly after a spill into water; therefore, a material classified as 

a Division 4.3 will not always be included in Table 2.
Use this list only when material is spilled in water. Page 335

HOW TO USE TABLE 3 – INITIAL ISOLATION AND PROTECTIVE ACTION 

DISTANCES FOR LARGE SPILLS FOR DIFFERENT QUANTITIES OF 

SIX COMMON TIH (PIH IN THE US) GASES

Table 3 lists Toxic Inhalation Hazard (TIH) materials that may be more commonly 

encountered. 

The selected materials are:

• UN1005 - Ammonia, anhydrous

• UN1017 - Chlorine

• UN1040 - Ethylene oxide and UN1040 – Ethylene oxide with nitrogen

• UN1050 - Hydrogen chloride, anhydrous and UN2186 - Hydrogen chloride, 

refrigerated liquid

• UN1052 - Hydrogen fluoride, anhydrous

• UN1079 - Sulfur dioxide/Sulphur dioxide

The materials are presented in numerical order of ID number and provide Initial Isolation 

and Protective Action Distances FOR LARGE SPILLS (more than 208 liters or 55 US 

gallons) involving different container types (therefore different volume capacities, see

ERG2024 USER’S GUIDE

For the purposes of this guidebook, the terms hazardous materials/dangerous goods are 

synonymous.

The 2024 Emergency Response Guidebook (ERG2024) was developed jointly by Transport 

Canada (TC), the U.S. Department of Transportation (DOT), and the Secretariat of 

Infrastructures, Communications and Transport of Mexico (SICT), with help from CIQUIME 

(Centro de Información Química para Emergencias) of Argentina.

This guidebook is for firefighters, police and other emergency services personnel who may 

be first to arrive at the scene of a transportation incident involving dangerous goods.

It is primarily a guide to help first responders to quickly: 

• identify the specific or generic hazards of material(s) involved in a transportation 

incident

• protect themselves and the general public during the initial response phase 

of the incident

For the purposes of this guidebook, “initial response phase” is the period after first responders 

arrive at the scene of an incident. During this phase, responders:

• confirm the presence and/or identification of dangerous goods

• start taking protective action and securing the area

• request the help of qualified personnel

This guide is designed for use at a dangerous goods incident on a highway or railroad. It may 

have limited value at fixed-facility locations, or onboard aircrafts or vessels.

This guide does not: 

• provide information on the physical or chemical properties of dangerous goods

• replace emergency response training, knowledge, or sound judgment

• address all possible circumstances that may be associated with a dangerous goods 

incident

ERG2024 incorporates dangerous goods lists from the most recent United Nations 

Recommendations, and from other international and national regulations.

Explosives are not listed individually (by either proper shipping name or ID number) but, 

under the general heading “Explosives”, they do appear:

• at the beginning of the ID Number index (yellow section)

• alphabetically in the Name of Material index (blue section)

Chemical and biological warfare agents are now found in the “Criminal or Terrorist Use of 

Chemical, Biological and Radiological Agents” section.
Page 345

The letter (P) following the guide number in the yellow and blue sections 

identifies materials that present a polymerization hazard under certain conditions. 

For example: UN1092 - Acrolein, stabilized GUIDE 131P.

First responders at the scene of a dangerous goods incident should not solely rely on this 

guidebook. Always seek specific information about any material in question as soon as 

possible. To do so:

• Contact the appropriate emergency response agency listed on the inside back cover.

• Call the emergency response telephone number on the shipping paper.

• Consult information on or accompanying the shipping paper.

BEFORE AN EMERGENCY – BECOME FAMILIAR WITH THIS GUIDEBOOK! In the 

U.S., according to the requirements of the U.S. Department of Labor’s Occupational Safety 

and Health Administration (OSHA, 29 CFR 1910.120) and regulations issued by the U.S. 

Environmental Protection Agency (EPA, 40 CFR Part 311), first responders must be trained 

in how to use this guidebook.

GUIDEBOOK CONTENTS

1- Yellow section: Index list of dangerous goods in order of ID number. The list displays the 

4-digit ID followed by its assigned emergency response guide and material name.

For example: ID No. GUIDE No. Name of Material

1090 127 Acetone

2- Blue section: Index list of dangerous goods in alphabetical order of material name. The list 

displays the name followed by its assigned emergency response guide and 4-digit ID number.

For example: Name of Material GUIDE No. ID No.

Sulfuric acid 137 1830

3- Orange section: All safety recommendations are provided here. It is made up of 62 

individual guides. Each guide recommends safety and emergency response procedures 

to protect yourself and the public. Each guide applies to a group of materials with similar 

chemical and toxicological characteristics. The guide title identifies the general hazards of 

the dangerous goods.

For example: GUIDE 124 - Gases - Toxic and/or Corrosive - Oxidizing.
Page 346

Each guide is divided into 3 main sections:

POTENTIAL HAZARDS: 

• Displays the hazards in terms of FIRE OR EXPLOSION and HEALTH effects upon 

exposure.

• Primary potential hazard is listed first.

• Consult this section first to help you make decisions about how to protect the 

emergency response team and surrounding population.

PUBLIC SAFETY: 

• Provides general information on initial precautionary measures to be taken by those 

first on scene.

• Provides general guidance on PROTECTIVE CLOTHING requirements and respiratory 

protection.

• Lists suggested EVACUATION distances for immediate precautionary measures, 

spills, and for fires (fragmentation hazard).

• When the material is highlighted in green in the yellow and blue sections, it directs 

the reader to consult Table 1, which lists Toxic Inhalation Hazard (TIH) (PIH in the 

U.S.) materials and water-reactive materials (green section).

EMERGENCY RESPONSE: 

• Outlines special precautions for incidents that involve FIRE, SPILL OR LEAK or 

chemical exposure.

• Lists several recommendations under each part to further assist your decision-making 

process.

• Provides specific FIRST AID guidance to use for a product or a guide in addition to the 

general first aid guidance for hazardous materials/dangerous goods incidents. General 

first aid guidance is found in the “General First Aid” section situated immediately after 

the “How to use the Orange Guides” section.

4- Green section: This section has 3 tables.

Table 1 - Initial Isolation and Protective Action Distances

Lists, by order of ID number: 

• TIH (PIH in the U.S.) materials

• water-reactive materials which produce toxic gases upon contact with water

These materials are highlighted in green in the yellow and blue sections so you can easily 

identify them.
Page 347

Table 1 provides two types of recommended safety distances: “initial isolation distances” 

and “protective action distances” for:

• small spills: 208 liters (55 US gallons) or less

• large spills: more than 208 liters (55 US gallons)

Within the “initial isolation distance”, protective clothing and respiratory protection is 

required. You should consider evacuating all people in all directions from the spill or leak 

source. This distance defines the radius of the “initial isolation zone” surrounding the spill in 

which people may be exposed to:

• dangerous concentrations upwind of the source

• life-threatening concentrations downwind of the source

The “protective action distances” are downwind distances from the spill or leak source, 

within which responders could carry out protective actions to:

• preserve the health and safety of emergency responders and the public

• evacuate and/or shelter-in-place people in this area (For more information, consult 

the “Protective Actions” section)

The “protective action distance” is divided into daytime and nighttime incidents because 

varying atmospheric conditions affect a hazardous area’s size. In fact, the quantity or 

concentration of the material’s vapor poses problems, not its mere presence. During the night, 

the air is generally calmer. This causes the vapor to disperse less and therefore creates a 

greater toxic zone. In daytime, the atmosphere is more active, so the vapor disperses more. 

As a result, there is a lower concentration of vapor in the surrounding air and the area that 

reaches toxic levels is smaller. Daytime is after sunrise and before sunset. Nighttime is 

between sunset and sunrise.

For example, in the case of a small spill of UN1955 - compressed gas, toxic, n.o.s., the 

“initial isolation distance” is 150 meters (500 feet); therefore its “initial isolation zone” is 

300 meters (1000 feet) in diameter. Its “protective action distance” is 1.0 kilometer (0.6 

miles) for daytime and 3.9 kilometers (2.4 miles) for nighttime.

Note 1: Some water-reactive materials have 2 entries in Table 1. They are identified by 

(when spilled on land) since they are TIH products and (when spilled in water) because 

they produce additional toxic gases when spilled in water.

For example: UN1746 - Bromine trifluoride and UN1836 - Thionyl chloride.

Note 2: If a water-reactive material only has one entry in Table 1 for (when spilled in water)

and the product is NOT spilled in water, Table 1 and Table 2 do not apply. You will find safe 

distances in the appropriate orange guide.

For example: UN1183 - Ethyldichlorosilane and UN1898 – Acetyl iodide.
Page 348

Table 2 - Water-Reactive Materials Which Produce Toxic Gases 

Lists:

• by order of ID number, materials which produce large amounts of Toxic Inhalation 

Hazard (TIH) gases when spilled in water; and

• TIH gases produced by these materials. 

You can easily identify water-reactive materials in Table 1, as their names are immediately 

followed by (when spilled in water).

NOTE: The TIH gases indicated in Table 2 are for information purposes only. These TIH 

gases have already been taken into consideration in the distances of Table 1.

For example, Table 2 indicates that UN1689 sodium cyanide, solid, when spilled in water, 

will generate hydrogen cyanide gas (HCN). In Table 1, you must refer to the distances for 

sodium cyanide, solid and not the distances for hydrogen cyanide gas.

Table 3 - Initial Isolation and Protective Action Distances for Large Spills for Different 

Quantities of Six Common TIH Gases

Lists the following 6 most common TIH materials:

• UN1005 - Ammonia, anhydrous

• UN1017 - Chlorine

• UN1040 - Ethylene oxide and UN1040 - Ethylene oxide with nitrogen

• UN1050 - Hydrogen chloride, anhydrous and UN2186 - Hydrogen chloride, refrigerated 

liquid

• UN1052 - Hydrogen fluoride, anhydrous

• UN1079 - Sulfur dioxide/Sulphur dioxide

Table 3 shows: 

• initial isolation and protective action distances for large spills (more than 208 liters 

or 55 US gallons)

• different container types (therefore different volume capacities) for daytime and 

nighttime, and for three different wind speeds (low, moderate and high)
Page 349

HOW TO CHOOSE THE APPROPRIATE ISOLATION AND PROTECTIVE ACTION 

DISTANCES

ERG2024 lists isolation or evacuation distances in 2 places:

• the individual guides (orange section)

• Table 1 – Initial Isolation and Protective Action Distances (green section)

If you are dealing with a non-TIH material (not highlighted in green in the yellow or blue 

section), 

• Go to the assigned guide for the material (orange section).

• Under EVACUATION, you will find:

− initial isolation distance as an immediate precautionary measure

− specific distances for spill or fire situations (fragmentation hazard)

− Please note that certain guides may also refer to Table 1. This is just a reminder 

for green highlighted materials only.

If you are dealing with a TIH or water-reactive material (green highlighted entries in the 

yellow or blue section):

If there is no fire:

• Go directly to Table 1 – Initial Isolation and Protective Action Distances (green section).

• Also, consult the assigned guide for the material (orange section).

If a fire is involved:

• Go directly to the assigned guide (orange section) and apply the distances found 

under EVACUATION - Fire.

• Also, consult Table 1 distances for residual material release.
Page 350

PROTECTIVE CLOTHING

STREET CLOTHING AND WORK UNIFORMS

These garments, such as uniforms worn by police and emergency medical services personnel, 

provide almost no protection from the harmful effects of hazardous materials/dangerous goods.

STRUCTURAL FIREFIGHTERS’ PROTECTIVE CLOTHING (SFPC)

This category of clothing, often called turnout or bunker gear, is the protective clothing 

firefighters normally wear during structural firefighting operations. It includes a helmet, coat, 

pants, boots, gloves and a hood to cover parts of the head that are not protected by the helmet 

and facepiece. It can be used with full-facepiece positive pressure self-contained breathing 

apparatus (SCBA). It should, at minimum, meet the OSHA Fire Brigades Standard (29 CFR 

1910.156) or NFPA 1851.

Structural firefighters’ protective clothing provides limited protection from heat and cold. It 

may not provide adequate protection from harmful vapors or liquids encountered during 

hazardous materials/dangerous goods incidents. 

Each guide includes a statement about the use of SFPC in incidents involving the materials 

referenced by that guide. Some guides state that SFPC provides limited protection. In those 

cases, the responder wearing SFPC and SCBA may be able to perform a quick “in-and-out” 

operation. However, this type of operation can place the responder at risk of exposure, injury 

or death. The incident commander makes the decision to do this only if there is an overriding 

benefit (for example, to perform an immediate rescue, turn off a valve to control a leak, etc.). 

Please note that the coverall-type protective clothing customarily worn to fight fires in forests or 

wildlands is not SFPC and is not recommended nor referred to elsewhere in this guidebook.

POSITIVE PRESSURE SELF-CONTAINED BREATHING APPARATUS (SCBA)

This apparatus provides a constant, positive pressure flow of air within the facepiece. 

You should always use an SCBA certified by NIOSH and the Department of Labor/Mine 

Safety and Health Administration, in accordance with:

• 42 CFR Part 84

• requirements for respiratory protection specified in OSHA 29 CFR 1910.134 

(Respiratory Protection) and/or 29 CFR 1910.156 (f) (Fire Brigades Standard)

• NFPA 1852

Chemical-cartridge respirators or other filtering masks are not acceptable substitutes for 

positive pressure SCBA. Demand-type SCBA does not meet the OSHA 29 CFR 1910.156 

(f)(1)(i) of the Fire Brigades Standard. 

RESPIRATORS

If you suspect a chemical warfare agent is involved in an incident, use NIOSH-certified 

respirators with CBRN protection.
Page 351

N95 respirators are the most common of the seven types of particulate filtering facepiece 

respirators. This product filters at least 95% of airborne particles (0.3 microns), but is not 

resistant to oil. N95 filtering facepiece respirators do not protect against gases and vapors.

Powered air-purifying respirators (PAPR) force ambient air through the air-purifying cartridge 

or filter into the facepiece. A PAPR does not supply oxygen or air from a separate source 

(e.g., cylinders).

CHEMICAL PROTECTIVE CLOTHING AND EQUIPMENT

For you to safely use this type of protective clothing and equipment, you need specific skills 

developed through training and experience. This type of special clothing may protect against 

one chemical but be readily permeated by chemicals for which it was not designed. Therefore, 

do not use this type of protective clothing unless it is compatible with the released material. 

Also, be aware that it offers little or no protection against heat and/or cold. 

Examples of this type of equipment have been described as:

(1) Vapor Protective Suits (NFPA 1991), also known as Totally-Encapsulating Chemical 

Protective Suits or Level A* protection (OSHA 29 CFR 1910.120, Appendix A & B)

(2) Liquid-Splash Protective Suits (NFPA 1992), also known as Level B* or C* protection 

(OSHA 29 CFR 1910.120, Appendix A & B), or suits for chemical/biological terrorism 

incidents (NFPA 1994), class 1, 2 or 3 Ensembles and Standard CAN/CGSB/

CSA-Z1610-11 – Protection of first responders from chemical, biological, radiological, 

and nuclear (CBRN) events

No single protective clothing material will protect you from all hazardous materials/dangerous 

goods. Do not assume any protective clothing is resistant to cold and/or heat or flame 

exposure, unless certified by the manufacturer (NFPA 1991 5-3 Flammability Resistance 

Test and 5-6 Cold Temperature Performance Test).

*Consult the glossary for more information about protection levels under the heading 

“Protective Clothing.”
Page 352

DECONTAMINATION

The ways to decontaminate people and equipment can vary. If you need help with 

decontamination, contact the emergency response telephone number provided on 

the shipping papers or the agencies listed on the inside back cover. These resources 

may be able to put you in contact with the chemical manufacturer to determine the 

appropriate procedure if not otherwise available.

Decontamination is the process of removing or neutralizing hazardous materials/dangerous 

goods that have contaminated people and equipment during an incident. 

Contamination happens in the area generally referred to as the Hot Zone. Everything and 

everyone entering this zone should be decontaminated when leaving, including emergency 

response personnel. This reduces the chances that more contamination will occur. 

There are two main types of contamination: 

• Direct contamination happens in the Hot Zone. 

• Cross contamination happens when someone or something outside the Hot Zone 

was not properly decontaminated and comes in contact with another object or person, 

usually in the Warm or Cold Zone. 

To decontaminate, you must:

• physically remove contaminants; and/or

• chemically neutralize contaminants*.

The NFPA 472, Chapter 3, describes the following four kinds of decontamination.

(1) Gross decontamination: Quickly removing surface contamination, which usually 

happens by mechanically removing the contaminant or rinsing with water from 

handheld hose lines, emergency showers, or other nearby water sources.

(2) Technical decontamination: Reducing contamination to a level as low as 

possible by chemical or physical methods. A hazmat team will perform this kind of 

decontamination. 

(3) Mass decontamination: Reducing or removing surface contaminants as fast as 

possible from a large number of people in potentially life-threatening situations.

(4) Emergency decontamination: Immediately reducing contamination of people 

in potentially life-threatening situations with or without formally setting up a 

decontamination corridor. This process should be performed upwind and uphill 

from victims. Responders should avoid contact with victims, runoff or spray from the 

decontamination process.

Emergency and mass decontamination can be done with firefighting and rescue operations 

equipment. Nozzles can be put on wide-angle fog patterns and sprayed towards the ground 

to create a decontamination shower. Responders can also place nozzles on the discharge 

ports of engines. 

Contaminated clothing and equipment must be removed after use and stored in a controlled 

area (Warm Zone) until cleanup procedures can begin. Sometimes protective clothing and 

equipment cannot be decontaminated and must be disposed of properly.

*Chemical neutralization releases heat. DO NOT PERFORM on a victim.
Page 353

FIRE AND SPILL CONTROL

FIRE CONTROL

Water is the most common and generally most available fire extinguishing agent. Use caution 

in selecting a fire extinguishing method, as there are many factors to consider. Water may 

be ineffective in fighting fires that involve some materials. 

Fires Involving a Spill of Flammable Liquids

These fires are usually controlled by applying a firefighting foam to the surface of the burning 

material.

Fighting flammable liquid fires requires: 

• foam concentrate that is chemically compatible with the burning material

• correct mixing of the foam concentrate with water and air

• careful application and maintenance of the foam blanket

There are two general types of firefighting foam: regular and alcohol-resistant. Examples of 

regular foam are protein-base, fluoroprotein, and aqueous film-forming foam (AFFF). 

You can control some flammable liquid fires, including many petroleum products, by applying 

regular foam. Other flammable liquids, including polar solvents (flammable liquids that are 

water soluble), such as alcohols and ketones, have different chemical properties. You cannot 

easily control a fire that involves these materials with regular foam, and should use alcoholresistant foam instead. 

Polar solvent fires may be difficult to control and require a higher foam application rate than 

other flammable liquid fires (see NFPA Standards 11 for further information). Refer to the 

appropriate guide to determine which type of foam to use. For flammable liquids which have 

subsidiary corrosive or toxic hazards, it is difficult to make specific recommendations. However, 

alcohol-resistant foam may be effective for many of these materials. 

Contact the emergency response telephone number on the shipping paper, or the appropriate 

emergency response agency, as soon as possible for guidance on the proper fire extinguishing 

agent to use. 

How you decide to control the fire depends on factors such as:

• incident location

• exposure hazards

• size of the fire

• environmental concerns

• availability of extinguishing agents and equipment at the scene

WATER-REACTIVE MATERIALS

Water is sometimes used to flush spills and reduce or direct vapors in spill situations. Some 

of the materials covered by this guidebook can react violently or even explosively with water. 

In these cases, consider letting the fire burn or leaving the spill alone (except to prevent its 

spreading by diking) until you can get more technical advice. 
Page 354

The applicable guides clearly warn you of these potentially dangerous reactions. Technical 

advice is required for these materials since:

• Water getting inside a ruptured or leaking container may cause an explosion.

• You may need to cool adjoining containers with water to prevent them from rupturing 

(exploding), or to prevent the fire spreading further.

• Water may be effective in mitigating an incident involving a water-reactive material, 

but only if you can apply it at a sufficient flooding rate for a long period.

• Products from the reaction with water may be more toxic, corrosive or undesirable 

than the product that caused the fire.

When you respond to an incident involving water-reactive materials, take into account:

• existing conditions, such as wind, precipitation, location and accessibility to the incident

• availability of agents to control the fire or spill

Because there are variables to consider, base your decision to use water on fires or spills 

involving water-reactive materials on information from a reliable source. For example, consult 

the material’s manufacturer through the emergency response telephone number or the 

appropriate emergency response agency listed on the inside back cover.

VAPOR CONTROL

Limiting the amount of vapor released from a pool of flammable or corrosive liquids is an 

operational concern. It requires proper protective clothing, specialized equipment, appropriate 

chemical agents and skilled personnel. Before you engage in vapor control, seek advice on 

tactics to be used from qualified personnel.

There are several ways to minimize the amount of vapors escaping from pools of spilled 

liquids, such as special foams, adsorbing agents, absorbents, and neutralizing agents. To 

be effective, you must select a method for the specific material involved, and use it in a way 

that mitigates, not worsens, the incident.

Where specific materials are known, such as at a manufacturing or storage facilities, the 

hazardous materials/dangerous goods response team should prearrange with the facility 

operators to select and stockpile these control agents before a spill.

In the field, first responders may not have the most effective vapor control agent for the material 

available. They will be more likely to have only water, and only one type of firefighting foam 

on their vehicles. If the available foam is not appropriate, they will probably use water spray. 

Because water is being used to form a vapor seal, care must be taken not to churn or further 

spread the spill during application. Vapors that do not react with water may be directed away 

from the site using the air currents surrounding the water spray. Before using water spray 

or other methods to safely control vapor emission or suppress ignition, get technical advice 

based on a specific chemical name.
Page 355

LIQUID SPILL CONTROL

Spill control is an important part of any hazardous materials/dangerous goods incident. Spills 

can have serious health, safety, and environmental consequences. There are many ways to 

deal with a liquid spill, like:

• diking

• damming, and

• absorbing

A liquid spill can be controlled by setting up a barrier around the spill area. Depending on the 

product involved, the spill can be contained with either inert or non-combustible absorbent 

materials.

Inert absorbent materials are granular. The most common types are:

• sand

• diatomaceous earth (a fine powder made from sedimentary rock)

• vermiculite, or

• clay

Non-combustible absorbents are usually not very flammable and can absorb a lot of liquid. 

These materials are usually made from synthetic materials, like:

• polypropylene

• polyethylene, or

• other synthetic fibers

Other absorbent materials that are easy to find include sawdust or clay litter. Please note 

the following:

• Sawdust should not be used to absorb flammable liquids or oxidizers since it can 

catch fire

• Clay litter should not be used to absorb acids since it may contain baking soda, which 

will react with acids

Before using an absorbent material, get technical advice to confirm its compatibility or test 

a small amount on the spill.
Page 356

CONSIDERATIONS FOR LITHIUM BATTERY AND ELECTRIC VEHICLE (EV) FIRES

FIRE CONTROL

Water spray cools batteries and helps suppress and slow the release of toxic gases but 

does not stop the chemical reaction (thermal runaway). Other extinguishing agents (CO2, 

dry chemical, etc.) can trap heat instead of removing it and could result in false (lower 

temperature) readings.

During an electric vehicle (EV) fire, consult the manufacturer’s specific emergency response 

guide for help with identifying high voltage and medium voltage cabling. DO NOT CUT 

THESE CABLES.

Most electric vehicles have emergency cut loops which are low voltage wire loops that can 

be cut to disconnect the high voltage system from the rest of the vehicle. If it is safe to do 

so, follow the manufacturer’s directions to disconnect the 12-volt battery. This will isolate the 

power to the high voltage battery and reduce risk of electric shock.

DAMAGED, DEFECTIVE, OR RECALLED LITHIUM BATTERIES

All lithium batteries can pose a fire risk, whether they are lithium metal or lithium ion, new 

or used. However, damaged, defective, or recalled (DDR) lithium batteries pose a higher 

risk than non-DDR lithium batteries because they are more likely to catch fire in a process 

known as “thermal runaway”.

Thermal runaway is a chain reaction that leads to a violent release of stored energy and 

flammable gas. This reaction can spread to other batteries or combustible materials that are 

nearby, which could lead to a large-scale thermal event with severe consequences.

Signs that a battery is damaged, defective, or recalled include:

• leaking electrolytes

• swollen or discolored battery casing

• odor or corrosion

• burn marks

• known conditions of use or misuse

• being recalled
Page 357

BLEVE AND HEAT INDUCED TEAR

BLEVE (BOILING LIQUID EXPANDING VAPOR EXPLOSION)

The following section presents important safety-related information on BLEVEs, including a 

table, to consider in a situation involving Liquefied Petroleum Gases (LPG), UN1075.

LPGs include the following flammable gases: 

• UN1011 - Butane • UN1077 - Propylene

• UN1012 - Butylene • UN1969 - Isobutane

• UN1055 - Isobutylene • UN1978 - Propane

A BLEVE occurs when a fire impinged or damaged tank car fails to contain its internal pressure 

and explodes with a sudden product release. This catastrophic failure is more likely to occur 

with damaged pressure tank cars, even in the absence of an active fire.

The main hazards from a LPG BLEVE are:

• Fire: If the released substance is ignited, there is an immediate fireball.

• Thermal radiation: At a distance of about 4 times the radius of a fireball, the heat 

radiated from a fireball is enough to burn exposed skin in 2 seconds. Wearing protective 

clothing limits the thermal radiation dose.

• Blast: A concussive force caused by the sudden release of the pressurized substance. 

For a BLEVE occurring out in the open, the blast strength at a distance of 4 times the 

radius of a fireball can break window glass and may cause minor damage to buildings.

• Projectiles: Tank failure can throw metal fragments over large distances. These 

fragments can and have been deadly.

The danger decreases as you move away from the BLEVE centre. The furthest-reaching 

hazard is projectiles.

For a video with information on critical safety issues concerning BLEVEs, please visit 

https://www.tc.gc.ca/eng/tdg/publications-menu-1238.html. 

HEAT INDUCED TEAR (HIT)

A heat induced tear (HIT) is a rupture of a NON-PRESSURE tank car containing flammable 

liquids when exposed to the intense heat of a fire. The metal will soften and the pressure in 

the tank car will increase which can lead to containment failure. The tear generally occurs 

at the vapor space (upper side) of the container, venting large quantities of flammable liquid 

and vapors at high speed. A fireball and an intense heat wave will occur.

Compared to BLEVEs, HITs rarely result in the projection of tank car fragments. Heat induced 

tearing has occurred within 20 minutes of the derailment and as long as 10+ hours following 

the initial fire. 

Responding to these types of incidents (BLEVE and HIT) requires specialized training, 

equipment and a tactical approach.
Page 358

BLEVE – SAFETY PRECAUTIONS

Use with caution. The following table gives a summary of tank properties, critical times, 

critical distances and cooling water flow rates for various tank sizes. This table is provided 

to give responders some guidance but it should be used with caution.

Tank dimensions are approximate and can vary depending on the tank design and 

application.

Minimum time to failure is based on severe torch fire impingement on the vapor space 

of a tank in good condition, and is approximate. Tanks may fail earlier if they are damaged 

or corroded. Tanks may fail minutes or hours later than these minimum times depending 

on the conditions. It has been assumed here that the tanks are not equipped with thermal 

barriers or water spray cooling.

Minimum time to empty is based on an engulfing fire with a properly sized pressure relief 

valve. If the tank is only partially engulfed, then time to empty will increase (i.e., if tank is 50% 

engulfed, then the tanks will take twice as long to empty). Once again, it has been assumed 

that the tank is not equipped with a thermal barrier or water spray.

Tanks equipped with thermal barriers or water spray cooling significantly increase the 

times to failure and the times to empty. A thermal barrier can reduce the heat input to a 

tank by a factor of ten or more. This means it could take ten times as long to empty the tank 

through the Pressure Relief Valve (PRV).

Fireball radius and emergency response distance is based on mathematical equations 

and is approximate. They assume spherical fireballs and this is not always the case.

Two safety distances for public evacuation. The minimum distance is based on tanks 

that are launched with a small elevation angle (i.e., a few degrees above horizontal). This is 

most common for horizontal cylinders. The preferred evacuation distance has more margin 

of safety since it assumes the tanks are launched at a 45 degree angle to the horizontal. 

This might be more appropriate if a vertical cylinder is involved.

It is understood that these distances are very large and may not be practical in a highly 

populated area. However, it should be understood that the risks increase rapidly the closer 

you are to a BLEVE. Keep in mind that the furthest reaching projectiles tend to come off in 

the zones 45 degrees on each side of the tank ends.

Water flow rate is based on 5 ( √capacity (USgal) ) = USgal/min needed to cool tank 

metal.

Warning: the data given are approximate and should only be used with extreme caution. 

For example, where times are given for tank failure or tank emptying through the pressure 

relief valve – these times are typical but they can vary from situation to situation. Therefore, 

never risk life based on these times.

Page 360

CRIMINAL OR TERRORIST USE OF CHEMICAL, BIOLOGICAL AND 

RADIOLOGICAL AGENTS

If you suspect an intentional release of a chemical, biological or radiological agent (CBRN), 

you should immediately contact your local emergency response authorities (911). Additionally, 

for CBRN incidents occurring:

• within the United States, call the National Response Center at 1-800-424-8802

• within Canada, call CANUTEC at 613-996-6666 (1-888-226-8832)

• within Mexico, call CENACOM at 555128-0000 extensions 36428, 36422, 36469, 

37807, 37810

• in other countries, consult the “24-hour emergency response telephone 

numbers” section.” 

The following is general guidance and does not serve as specialized incident response 

training. Do not enter the scene without appropriate training and equipment.

Initial actions to consider in a potential CBRN/terrorism event:

• First responders must ensure their own safety.

• Avoid using cell phones, radios, etc. within 100 meters (300 feet) of a suspect device.

• If known, request trained specialist resources.

• Set up incident command upwind and uphill of the area.

• Do not touch or move suspicious packages or containers.

• Be cautious about the potential presence of secondary devices (e.g., improvised 

explosive devices (IEDs)).

• Avoid contamination.

• Limit access to only those responsible for rescue of victims or assessment of unknown 

materials or devices.

• Evacuate and isolate people who were potentially exposed to hazardous materials/

dangerous goods to an area away from the scene, preferably upwind and uphill while 

avoiding physical contact to the extent possible.

• Isolate contaminated areas and secure the scene for analysis of material.

First responders can use the following information to make an initial assessment of a situation 

they suspect involves criminal or terrorist use of chemical agents, biological agents and/

or radioactive materials (CBRN). To help with this, the following paragraphs have a list of 

observable indicators that a CB agent or radioactive material has been used or is present. 

This section ends with a Safe Stand-Off Distance Chart for various threats when improvised 

explosive devices (IEDs) are involved.

DIFFERENCES BETWEEN A CHEMICAL, BIOLOGICAL AND RADIOLOGICAL AGENT

Chemical and biological agents as well as radioactive materials can be dispersed in the air 

we breathe, the water we drink, or on surfaces we physically contact. Dispersion methods 

may be as simple as opening a container or using conventional (garden) spray devices, or 

as elaborate as detonating an improvised explosive device.
Page 361

Chemical incidents are characterized by the rapid onset of medical symptoms (in minutes 

to hours) and easily observed signatures (colored residue, dead foliage, pungent odor, dead 

insects and animals).

Biological incidents are characterized by the onset of symptoms in hours to days. Typically, 

there will be no characteristic signatures because biological agents are usually odorless and 

colorless. Because of the delayed onset of symptoms, the affected area may be greater due 

to the movement of infected people.

Radiological incidents are characterized by the onset of symptoms, if any, in days to weeks 

or longer. Typically, there will be no characteristic signatures because radioactive materials 

are usually odorless and colorless. Specialized equipment is needed to determine the size of 

the affected area, and if the level of radioactivity is an immediate or long-term health hazard. 

Because it is impossible to detect radioactivity without special equipment, the affected area 

may be greater due to the migration of contaminated people. 

The most probable sources would not generate enough radiation to kill people or cause severe 

illness. In a radiological incident generated by a “dirty bomb,” or radiological dispersal device 

(RDD), in which a conventional explosive is detonated to spread radioactive contamination, 

the primary hazard is from the explosion. However, certain radioactive materials dispersed 

in the air could contaminate up to several city blocks, creating fear and possibly panic, and 

needing potentially costly cleanup.

INDICATORS OF A POSSIBLE CHEMICAL INCIDENT

Dead animals/birds/fish Not just an occasional road kill, but numerous animals 

(wild and domestic, small and large), birds, and fish in 

the same area.

Lack of insect life If normal insect activity (ground, air, and/or water) is 

missing, check the ground, water surface or shore line 

for dead insects. If near water, check for dead fish and/

or aquatic birds.

Unexplained odors Possible odors include fruity, flowery, sharp, pungent, 

garlic, horseradish-like, bitter almonds, peach kernels, or 

newly mown hay. The odor is completely out of character 

with its surroundings.

Unusual numbers of dying or

sick people (mass casualties)

Health problems including nausea, disorientation, 

difficulty in breathing, convulsions, localized sweating, 

conjunctivitis (reddening of eyes), erythema (reddening 

of skin) and death.

Pattern of casualties Casualties will likely be distributed downwind, or if 

indoors, by the air ventilation system.
Page 362

Blisters or rashes Numerous people experiencing unexplained water-like 

blisters, weals (like bee stings), and/or rashes.

Illness in confined area Different casualty rates for people working indoors versus 

outdoors dependent on where the agent was released.

Unusual liquid droplets Numerous surfaces show oily droplets or film; numerous 

water surfaces have an oily film (no recent rain).

Different-looking areas Not just a patch of dead weeds, but trees, shrubs, bushes, 

food crops, and/or lawns that are dead, discolored, or 

withered (no current drought).

Low-lying clouds Low-lying cloud or fog-like condition not consistent with 

its surroundings.

Unusual metal debris Unexplained bomb or munitions-like material, especially 

if it contains a liquid.

INDICATORS OF A POSSIBLE BIOLOGICAL INCIDENT

Unusual numbers of sick or 

dying people or animals

Any number of symptoms may occur. Casualties may 

occur hours to days after an incident has occurred. 

The time required before symptoms are observed is 

dependent on the agent.

Unscheduled and unusual

spray being disseminated

Especially if outdoors during periods of darkness.

Abandoned spray devices Devices may not have distinct odors.

INDICATORS OF A POSSIBLE RADIOLOGICAL INCIDENT

Radiation Symbols Containers may display a “propeller” radiation symbol.

Unusual metal debris Unexplained bomb or munitions-like material.

Heat-emitting material Material that is hot or seems to emit heat without any 

sign of an external heat source.

Glowing material Strongly radioactive material may emit or cause 

radioluminescence.

Sick people/animals In very improbable scenarios there may be unusual 

numbers of sick or dying people or animals. Casualties 

may occur hours to days or weeks after an incident 

has occurred. The time required before symptoms are 

observed is dependent on the radioactive material used, 

and the dose received. Possible symptoms include skin 

reddening or vomiting.
Page 363

PERSONAL SAFETY CONSIDERATIONS

When you approach a scene that may involve CB agents or radioactive materials, the most 

critical thing to consider is your safety and that of other responders.

Use protective clothing and respiratory protection of an appropriate level of safety. In incidents 

where you suspect that CBRN materials have been used as weapons, NIOSH-certified 

respirators with CBRN protection are highly recommended. Be aware that you may not be 

able to verify or identify CB agents or radioactive materials, especially in the case of biological 

or radiological agents.

The following actions apply to a chemical, biological or radiological incident. This guidance 

is general. Responders will need to apply it on a case-by-case basis.

Approach and response strategies:

• Minimize exposure time.

• Maximize the distance between you and the item that is likely to harm you.

• Use cover as protection.

• Wear appropriate personal protective equipment and respiratory protection.

• Identify and estimate the hazard by using the indicators above.

• Isolate the area and secure the scene.

• Isolate and decontaminate potentially contaminated people as soon as possible.

• To the extent possible, take measures to limit the spread of contamination. 

In the event of a chemical incident, the fading of chemical odors does not necessarily indicate 

reduced vapor concentrations. Some chemicals deaden the senses, giving you the false 

perception that the chemical is no longer present.

If there is any indication that an area may be contaminated with radioactive materials, 

including the site of any non-accidental explosion, responders:

• should be equipped with radiation detection equipment 

• should have adequate training in how to use this equipment

This equipment should be designed to also alert responders when an unacceptable ambient 

dose rate or ambient dose has been reached.
Page 364

DECONTAMINATION MEASURES

For chemical and biological agents: Emergency responders should follow standard 

decontamination procedures (flush-strip-flush). Mass casualty decontamination should begin 

as soon as possible by stripping all clothing, and flushing with soap and water. For further 

information, contact the agencies listed on the inside back cover of this guidebook.

For people contaminated with radioactive material: Take care to minimize the spread 

of the contamination to the extent possible. Move them to a low radiation area if necessary, 

and if it can be done safely. Remove their clothing and place it in a clearly marked and 

sealed receptacle, such as a plastic bag, for later testing. Use decontamination methods 

described above, but avoid breaking the skin (e.g., vigorous brushing). External radiological 

contamination on intact skin rarely causes a high enough dose to be a hazard, to either the 

contaminated individual or the first responders. For this reason, prioritize medical stabilization 

for a contaminated injured individual.

NOTE: The above information was developed in part by the Department of National Defence 

(Canada), the U.S. Department of the Army, Aberdeen Proving Ground and the 

Federal Bureau of Investigation (FBI).

CHEMICAL AND BIOLOGICAL WARFARE AGENTS 

Chemical and biological warfare agents do not have an assigned ID number because they 

are not commercially transported. In an emergency situation, the assigned guide (orange 

section) will provide guidance for the initial response.

The volumes used for the chemical warfare agents’ distances are:

• Small release consists of a discharge up to 2 kg (4.4 lbs.)

• Large release consists of a discharge up to 25 kg (55 lbs.)

Biological Warfare Agents:

Biological agents Pathogens (bacteria, viruses, etc.) that are dispersed 

with criminal intent. They can cause disease or death in 

otherwise healthy humans.

Examples: Anthrax, plague, smallpox virus.

Refer to GUIDE 158.

Toxins Poisonous or toxic material from a plant, animal, or 

bacterial source.

Examples: Botulinum toxin, ricin.

IMPROVISED EXPLOSIVE DEVICE (IED)

An IED is a “homemade” bomb and/or destructive device used to destroy, incapacitate, harass, 

or distract. Because they are improvised, IEDs can come in many forms, ranging from a small 

pipe bomb to a sophisticated device capable of causing massive damage and loss of life.

The following table predicts the damage radius based on the volume or weight of explosive 

(TNT equivalent) and the type of bomb.

GLOSSARY

Adsorbed gas A gas which sticks (adsorbs) to the surface of a solid and porous 

material (such as activated charcoal) contained within a metal 

cylinder. This results in an internal cylinder pressure of less than 

101.3 kPa at 20°C (14 psi at 68°F) and less than 300 kPa at 50°C 

(43 psi at 122°F). These pressures are much lower than those of 

conventional cylinders containing compressed or liquefied gases.

AEGL(s) Acute Exposure Guideline Level(s), AEGLs represent threshold 

exposure limits for the general public after a once-in-a-lifetime, 

or rare, exposure and are applicable to emergency exposure 

periods ranging from 10 minutes to 8 hours. Three levels AEGL1, AEGL-2 and AEGL-3 are developed for each of five exposure 

periods (10 and 30 minutes, 1 hour, 4 hours, and 8 hours) and 

are distinguished by varying degrees of severity of toxic effects; 

see AEGL-1, AEGL-2 and AEGL-3.

AEGL-1 AEGL-1 is the airborne concentration (expressed as parts 

per million or milligrams per cubic meter [ppm or mg/m3]) of a 

substance above which it is predicted that the general population, 

including susceptible individuals, could experience notable 

discomfort, irritation, or certain asymptomatic, non-sensory 

effects. However, the effects are not disabling and are transient 

and reversible upon cessation of exposure.

AEGL-2 AEGL-2 is the airborne concentration (expressed as ppm or mg/

m3) of a substance above which it is predicted that the general 

population, including susceptible individuals, could experience 

irreversible or other serious, long-lasting adverse health effects 

or an impaired ability to escape.

AEGL-3 AEGL-3 is the airborne concentration (expressed as ppm or mg/

m3) of a substance above which it is predicted that the general 

population, including susceptible individuals, could experience 

life-threatening health effects or death.

Air-Reactive See “Pyrophoric”.

Alcohol-resistant foam A foam that is resistant to polar chemicals such as ketones and 

esters which may break down other types of foam.

BLEVE Boiling Liquid Expanding Vapor Explosion

Boil over A sudden increase in fire intensity associated with the expulsion 

of burning flammable liquid caused by the boiling of water that 

has accumulated in the bottom of a tank car.
Page 370

GLOSSARY

Burn Refers to either a chemical or thermal burn, the former may 

be caused by corrosive substances and the latter by liquefied 

cryogenic gases, hot molten substances, or flames.

Carcinogen A substance or mixture which induces cancer or increases its 

incidence.

Category A An infectious substance that poses a high risk to the health of 

individuals and/or animals or public health. These substances can 

cause serious disease and can lead to death. Effective treatment 

and preventative measures may not be available.

Category B An infectious substance that poses a low to moderate risk 

to individuals and/or animals and/or public health. These 

substances are unlikely to cause serious disease. Effective 

treatment and preventative measures are available.

CBRN Chemical, biological, radiological or nuclear agent.

CO2 Carbon dioxide gas.

Cold zone Area where the command post and support functions that 

are necessary to control the incident are located. This is also 

referred to as the clean zone, green zone or support zone in 

other documents. (EPA Standard Operating Safety Guidelines, 

OSHA 29 CFR 1910.120, NFPA 472).

Combustible In this guidebook, a solid or liquid capable of burning but 

does not catch fire as easily as a flammable liquid. See 

“Combustible Liquid”.

Combustible liquid Liquids which have a flash point greater than 60°C (140°F) and 

below 93°C (200°F). U.S. regulations permit a flammable liquid 

with a flash point between 38°C (100°F) and 60°C (140°F) to be 

reclassed as a combustible liquid.
Page 371

GLOSSARY

Compatibility Group Letters identify explosives that are deemed to be compatible. 

The definition of these Compatibility Groups in this Glossary are 

intended to be descriptive. Please consult the transportation of 

hazardous materials/dangerous goods or explosives regulations 

of your jurisdiction for the exact wording of the definitions. Class 

1 materials are considered to be “compatible” if they can be 

transported together without significantly increasing either the 

probability of an incident or, for a given quantity, the magnitude 

of the effects of such an incident.

A Substances which are expected to mass detonate very 

soon after fire reaches them.

B Articles which are expected to mass detonate very soon 

after fire reaches them.

C Substances or articles which may be readily ignited and 

burn violently without necessarily exploding.

D Substances or articles which may mass detonate (with 

blast and/or fragment hazard) when exposed to fire.

E & F Articles which may mass detonate in a fire.

G Substances and articles which may mass explode and 

give off smoke or toxic gases.

H Articles which in a fire may eject hazardous projectiles 

and dense white smoke.

J Articles which may mass explode.

K Articles which in a fire may eject hazardous projectiles 

and toxic gases.

L Substances and articles which present a special risk and 

could be activated by exposure to air or water.

N Articles which contain only extremely insensitive

detonating substances and demonstrate a negligible 

probability of accidental ignition or propagation.

S Packaged substances or articles which, if accidentally 

initiated, produce effects that are usually confined to the 

immediate vicinity.

Control temperature The maximum temperature at which a temperature-controlled 

substance can be safely transported. Above this temperature, 

self-accelerating decomposition or polymerization may occur.
Page 372

GLOSSARY

Control zones Designated areas at hazardous materials/dangerous goods 

incidents, based on safety and the degree of hazard. Many terms 

are used to describe control zones; however, in this guidebook, 

these zones are defined as the hot/exclusion/red/restricted zone, 

warm/contamination reduction/yellow/limited access zone, and 

cold/support/green/clean zone. (EPA Standard Operating Safety 

Guidelines, OSHA 29 CFR 1910.120, NFPA 472).

Criticality safety 

index (CSI)

A number value assigned to packages and overpacks containing 

fissile materials that limits the number of packages containing fissile 

materials during transportation.

Cryogenic liquid A refrigerated, liquefied gas that has a boiling point colder than 

-90°C (-130°F) at atmospheric pressure or is handled or transported 

at a temperature equal to or less than -100°C (-148°F).

Decomposition 

products

Products of a chemical or thermal break-down of a substance.

Decontamination The removal of hazardous materials/dangerous goods from 

personnel and equipment to the extent necessary to prevent 

potential adverse health effects. For more information, consult the 

“Decontamination” section.

Dry chemical A preparation designed for fighting fires involving flammable 

liquids, pyrophoric substances and electrical equipment. 

Common types contain sodium bicarbonate or potassium 

bicarbonate.

Edema The accumulation of an excessive amount of watery fluid in 

cells and tissues. Pulmonary edema is an excessive buildup of 

water in the lungs, for instance, after inhalation of a gas that is 

corrosive to lung tissue.

ERPG(s) Emergency Response Planning Guideline(s). Values intended 

to provide estimates of concentration ranges above which one 

could reasonably anticipate observing adverse health effects; 

see ERPG-1, ERPG-2 and ERPG-3.

ERPG-1 The maximum airborne concentration below which it is believed 

nearly all individuals could be exposed for up to 1 hour without 

experiencing more than mild, transient adverse health effects or 

without perceiving a clearly defined objectionable odor.

ERPG-2 The maximum airborne concentration below which it is believed 

nearly all individuals could be exposed for up to 1 hour without 

experiencing or developing irreversible or other serious health 

effects or symptoms that could impair an individual’s ability to 

take protective action.
Page 373

GLOSSARY

ERPG-3 The maximum airborne concentration below which it is believed 

nearly all individuals could be exposed for up to 1 hour without 

experiencing or developing life-threatening health effects.

Evacuate Evacuate aims to protect as many people as possible by 

removing persons from inside a zone safely. If removal is too 

risky, sheltering-in-place can also be considered in this zone.

Flammable liquid A liquid that has a flash point of 60°C (140°F) or lower.

Flash point Lowest temperature at which a liquid or solid gives off vapor in 

such a concentration that, when the vapor combines with air near 

the surface of the liquid or solid, a flammable mixture is formed. 

Hence, the lower the flash point, the more flammable the material.

Flooding quantities Minimum of 1900 L/min (500 US gal/min) of water.

Hazard zones 

(Inhalation Hazard 

Zones)

HAZARD 

ZONE A:

Gases: LC50 of less than or equal to 200 ppm, 

Liquids: V equal to or greater than 500 LC50 and 

LC50 less than or equal to 200 ppm.

HAZARD 

ZONE B:

Gases: LC50 greater than 200 ppm and less 

than or equal to 1000 ppm, Liquids: V equal to 

or greater than 10 LC50; LC50 less than or equal 

to 1000 ppm and criteria for Hazard Zone A are 

not met.

HAZARD 

ZONE C:

LC50 greater than 1000 ppm and less than or 

equal to 3000 ppm.

HAZARD 

ZONE D:

LC50 greater than 3000 ppm and less than or 

equal to 5000 ppm.

Please note: even though the term “zone” is used, hazard zones 

are not an actual area or distance. How zones are assigned is 

strictly a function of the lethal concentration 50 (LC50) of the 

product. For example, TIH Zone A is more toxic than Zone D. 

High expansion foam Foams that have a high expansion ratio (over 1:200) with a low 

water content.

Hot zone Area immediately surrounding a hazardous materials/dangerous 

goods incident which extends far enough to prevent adverse 

effects from the released product to personnel outside the zone. 

This zone is also referred to as exclusion zone, red zone or 

restricted zone in other documents. (EPA Standard Operating 

Safety Guidelines, OSHA 29 CFR 1910.120, NFPA 472).

IED See “Improvised Explosive Device”.

Immiscible In this guidebook, means that a material does not mix readily 

with water.

in populations of cells and/or organisms. Mutation means a 

permanent change in the amount or structure of the genetic 

material in a cell.

Narcotic A substance which acts as a central nervous system depressor 

producing effects such as drowsiness, narcosis, reduced 

alertness, loss of reflexes, lack of coordination, and vertigo. 

These effects can also be manifested as severe headache or 

nausea, and can lead to reduced judgment, dizziness, irritability, 

fatigue, impaired memory function, deficit in perception and 

coordination, reaction time, or sleepiness.

n.o.s. These letters refer to “not otherwise specified”. The entries 

which use this description are generic names such as “Corrosive 

liquid, n.o.s.” This means that the actual chemical name for that 

corrosive liquid is not listed in the regulations; therefore, a generic 

name must be used to describe it on shipping papers.

Noxious In this guidebook, means that a material may be harmful or 

injurious to health or physical well-being.
Page 375

GLOSSARY

Organic peroxide An organic (carbon-containing) compound having two oxygen 

atoms joined together. Organic peroxides are thermally 

unstable chemicals. They may have one or more of the following 

properties: be liable to explosive decomposition; burn rapidly; 

be sensitive to impact or friction; react dangerously with other 

substances.

Oxidizer A chemical which supplies its own oxygen and which helps other 

combustible material burn more readily.

P See “Polymerization”.

Packing Group The Packing Group (PG) is assigned based on the degree of 

danger presented by the hazardous material/dangerous good:

PG I : Great danger

PG II : Medium danger

PG III : Minor danger

PG See “Packing Group”.

pH pH is a value that represents the acidity or alkalinity of a water 

solution. Pure water has a pH of 7. A pH value below 7 indicates 

an acid solution (a pH of 1 is extremely acidic). A pH above 7 

indicates an alkaline solution (a pH of 14 is extremely alkaline). 

Acids and alkalies (bases) are commonly referred to as corrosive 

materials.

PIH Poison Inhalation Hazard. See “TIH”.

Polar A molecule in which one side of the molecule has a partial 

positive charge while another side has a partial negative charge. 

Examples includes alcohols and ketones.

Polymerization A chemical reaction that often produces heat and pressure. 

Once initiated, the reaction is accelerated by the heat that it 

produces. The uncontrolled buildup of heat and pressure can 

cause a fire or an explosion, or can rupture closed containers. 

The letter (P) following a guide number in the yellow and blue 

sections identifies a material that may polymerize violently 

under high temperature conditions or contamination with other 

products during a transportation incident. It is also used to identify 

materials that have a strong potential for polymerization in the 

absence of an inhibitor due to depletion of this inhibitor caused 

by accident conditions.

ppm Parts per million. (1 ppm equals 1 mL/m3).
Page 376

GLOSSARY

Protective clothing In this guidebook, protective clothing includes both respiratory 

and physical protection. One cannot assign a level of protection 

to clothing or respiratory devices separately. These levels were 

accepted and defined by response organizations such as U.S. 

Coast Guard, NIOSH, and U.S. EPA.

Level A: SCBA plus totally encapsulating chemical resistant

clothing (permeation resistant).

Level B: SCBA plus hooded chemical resistant clothing (splash 

suit).

Level C: Full or half-face respirator plus hooded chemical

resistant clothing (splash suit).

Level D: Coverall, including structural firefighters’ protective 

clothing (SFPC), with no respiratory protection.

SCBA: Self-contained breathing apparatus.

For more information, consult the “Protective Clothing” section.

Pyrophoric A material which ignites spontaneously upon exposure to air 

(or oxygen).

Radiation Authority As referred to in GUIDES 161 through 166 for radioactive 

materials, the Radiation Authority is either a Federal, state/

provincial agency or state/province designated official. The 

responsibilities of this authority include evaluating radiological 

hazard conditions during normal operations and during 

emergencies. If the identity and telephone number of the authority 

are not known by emergency responders, or included in the local 

response plan, the information can be obtained from the agencies 

listed on the inside back cover. They maintain a periodically 

updated list of radiation authorities.

Radioactivity The property of some substances to emit invisible and potentially 

harmful radiation.

Refrigerated liquid See “Refrigerated liquefied gas”.

Refrigerated liquefied 

gas

A gas which when packaged for transport is made partially liquid 

because of its low temperature. See “Cryogenic liquid”.

Respiratory sensitizer A substance that induces hypersensitivity of the airways following 

inhalation of the substance.

Right-of-way A defined area on a property containing one or more highpressure natural gas pipelines.

Self-heating material Material that may spontaneously ignite or generate heat on 

contact with oxygen (in air) after long periods of time (hours or 

days).
Page 377

GLOSSARY

Self-reactive material Material that is thermally unstable and produces heat upon 

decomposition, even without participation of air.

Shelter-in-place People should seek shelter inside a building and remain inside 

until the danger passes. Sheltering-in-place is used when 

evacuating the public would cause greater risk than staying 

where they are, or when an evacuation cannot be performed. 

Direct the people inside to close all doors and windows and to 

shut off all ventilating, heating and cooling systems. In-place 

protection (shelter-in-place) may not be the best option if (a) the 

vapors are flammable; (b) if it will take a long time for the gas to 

clear the area; or (c) if buildings cannot be closed tightly. Vehicles 

can offer some protection for a short period if the windows are 

closed and the ventilating systems are shut off. Vehicles are not 

nearly as effective as buildings for in-place protection.

Skin corrosion The production of irreversible damage to the skin following the 

application of a test substance for up to 4 hours.

Skin irritation The production of reversible damage to the skin following the 

application of a test substance for up to 4 hours.

Skin sensitizer A substance that will induce an allergic response following skin 

contact.

Small spill A spill that involves quantities that are 208 liters (55 US gallons) 

or less. This generally corresponds to a spill from a single small 

package (for example, a drum), a small cylinder, or a small leak 

from a large package.

Specific gravity Weight of a substance compared to the weight of an equal volume 

of water at a given temperature. Specific gravity less than 1 

indicates a substance is lighter than water; specific gravity greater 

than 1 indicates a substance is heavier than water.

Spontaneously 

combustible material

In this guidebook, a spontaneously combustible material means 

a pyrophoric (air-reactive) material or self-heating material. Refer 

to each term in the glossary.
Page 378

GLOSSARY

Straight or solid streams Method used to apply or distribute water from the end of a 

hose. The water is delivered under pressure for penetration. 

In an efficient stream, approximately 90% of the water passes 

through an imaginary circle 38 cm (15 inches) in diameter at 

the breaking point. Hose solid streams are typically created by 

passing water through a non-adjustable bore tip. On the other 

hand, hose straight streams originate from fog nozzles that are 

dialed into a straight stream. Hose (solid or straight) streams are 

frequently used to cool tanks and other equipment exposed to 

flammable liquid fires, or for washing burning spills away from 

danger points. However, these streams will cause a spill fire to 

spread if improperly used or when directed into open containers 

of flammable and combustible liquids.

Thermal runaway A chain reaction that leads to a violent release of stored energy 

and flammable gas. This reaction can spread to other batteries 

or combustible materials that are nearby, which could lead to a 

large-scale thermal event with severe consequences.

TIH Toxic Inhalation Hazard. Term used to describe gases and 

volatile liquids that are toxic when inhaled (same as PIH). These 

materials pose a known hazard to human health during transport 

or is presumed to be toxic to humans because of animal-based 

studies.

V Saturated vapor concentration in air of a material in mL/m3 (ppm) 

at 20°C and standard atmospheric pressure.

Vapor density Weight of a volume of pure vapor or gas (with no air present) 

compared to the weight of an equal volume of dry air at the same 

temperature and pressure. A vapor density less than 1 (one) 

indicates that the vapor is lighter than air and will tend to rise. 

A vapor density greater than 1 (one) indicates that the vapor is 

heavier than air and may travel along the ground.

Vapor pressure Pressure at which a liquid and its vapor are in equilibrium at a 

given temperature. Liquids with high vapor pressures evaporate 

rapidly.

Viscosity Measure of a liquid’s internal resistance to flow. This property is 

important because it indicates how fast a material will leak out 

through holes in containers or tanks.
Page 379

GLOSSARY

Warm zone Area between Hot and Cold zones where personnel and 

equipment decontamination and hot zone support take place. It 

includes control points for the access corridor and thus assists 

in reducing the spread of contamination. Also referred to as 

the contamination reduction corridor (CRC), contamination 

reduction zone (CRZ), yellow zone or limited access zone in 

other documents. (EPA Standard Operating Safety Guidelines, 

OSHA 29 CFR 1910.120, NFPA 472).

Water insoluble A substance that does not easily dissolve in water.

Water-Reactive Material In this guidebook, a material which produces a large amount of 

toxic gas when it comes in contact with water.

Water-sensitive Substances which may produce flammable, toxic and/or corrosive 

decomposition products upon contact with water.

Water soluble A substance that easily dissolves in water. Polar substances are 

generally soluble in water.

Water spray (fog) Method or way to apply or distribute water. The water is finely 

divided to provide for high heat absorption. Water spray patterns 

can range from about 10 to 90 degrees. Water spray streams can 

be used to extinguish or control the burning of a fire or to provide 

exposure protection for personnel, equipment, buildings, etc. This 

method can be used to absorb vapors, knock-down vapors 

or disperse vapors. Direct a water spray (fog), rather than a 

straight or solid stream, into the vapor cloud to accomplish 

any of the above.

Water spray is particularly effective on fires of flammable liquids 

and volatile solids having flash points above 37.8°C (100°F).

Regardless of the above, water spray can be used successfully 

on flammable liquids with low flash points. The effectiveness 

depends particularly on the method of application. With proper 

nozzles, even gasoline spill fires of some types have been 

extinguished when coordinated hose lines were used to sweep 

the flames off the surface of the liquid. Furthermore, water 

spray carefully applied has frequently been used with success 

in extinguishing fires involving flammable liquids with high flash 

points (or any viscous liquids) by causing frothing to occur only 

on the surface, and this foaming action blankets and extinguishes 

the fire.

3. EMERGENCY RESPONSE ASSISTANCE PLANS (Applies in Canada ONLY)

An ERAP or Emergency Response Assistance Plan is a Transport Canada approved plan 

that describes what is to be done in the event of a transportation incident involving certain 

high-risk dangerous goods that require specialized emergency response personnel and 

equipment.

Once implemented, a plan can be used to assist local emergency responders either 

remotely or on site, by offering technical and emergency response advice and resources. 

ERAP resources are often integrated with plans from carriers and local or provincial 

authorities to help mitigate the consequences of an incident.

For shipments that require an ERAP, an ERAP reference number and telephone number 

to obtain assistance will be included on the shipping paper. Anyone can call the ERAP 

telephone number. If additional information is required, or to determine if the product 

involved in the emergency requires an ERAP, contact CANUTEC.

CANUTEC may be called at 1-888-CANUTEC (226-8832) 

or collect at 613-996-6666 (24 hours)

NATIONAL RESPONSE CENTER (NRC) 

The NRC, which is operated by the U.S. Coast Guard, receives reports required when 

hazardous materials are spilled. After receiving notification of an incident, the NRC will 

immediately notify the appropriate Federal On-Scene Coordinator and concerned Federal 

agencies. Federal law requires that anyone who releases into the environment a reportable 

quantity of a hazardous material (including oil when water is, or may be affected) or a 

material identified as a marine pollutant, must immediately notify the NRC. When in doubt 

as to whether the amount released equals the required reporting levels for these materials, 

the NRC should be notified.

CALL NRC (24 hours) 

1-800-424-8802
