**Required learning objectives are to be able to:**
**Protect person from contamination by donning PPE**
**Remove potentially contaminated PPE without contaminating person **
**Recognize limitations of PPE**
**Know State and local work rules, policies and procedures, as well as those established by CSEPP**

**Objectives**

## CSEPP planning guidance does not provide for deployment of civilian emergency workers into areas which are known or suspected to be contaminated with chemical weapon agent until monitoring and sampling confirms that concentrations are within range for which PPE provides protection

To provide protection in event of entry into contaminated areas, individuals identified in state and local plans as initial off-site emergency workers will be issued PPE appropriate for prescribed job functions

**CSEPP planning guidance does not provide for deployment of civilian emergency workers into areas which are known or suspected to be contaminated with chemical weapon agent until monitoring and sampling confirms that concentrations are within range for which PPE provides protection**
**To provide protection in event of entry into contaminated areas, individuals identified in state and local plans as initial off-site emergency workers will be issued PPE appropriate for prescribed job functions**

**CSEPP Approach to PPE**

## On-Post Response Program

**Guided by U.S. Department of Army Pamphlet 50-6, Chemical Accident or Incident Response and Assistance (CAIRA) Operations**
**Pamphlet 50-6 describes Army functions, responsibilities, organizations, and procedures for responding to chemical weapon agent events**

## Off-Post Civilian Response

**Actions limited to those that protect general population, as documented in State and local emergency plans**
**Emergency plans describe functions, responsibilities, organizations, and procedures of off-site response to incidents involving Army chemical weapon agents from initial notification by Army that a release has occurred through end of incident**

## Off-Site Emergency Worker Functions

**May perform variety of functions including: **
**Controlling evacuation traffic **
**Providing emergency medical services**
**Performing emergency decontamination**

## Work Intensities

**Physical activities needed to perform duties vary in degree of complexity, movement and level of exertion**
**Emergency workers staffing traffic control points will be performing less strenuous tasks**
**Emergency workers assigned to a decontamination station or to medical services must perform more physical tasks**

## Governmental PPE Requirements

**U.S. Government requires that employer provide you with PPE if it is required on your job**
**Code of Federal Regulations (CFR) prescribes guidelines for training, protective clothing and equipment**
**Other State and local regulations may specify types of PPE for specific positions or tasks in dealing with range of hazardous materials**
**You should be familiar with local and job-specific requirements in your area**

## Who Needs PPE and Training

**All persons (including volunteers) designated as part of the emergency response (e.g., police, medics, paramedics, firefighters, medical personnel) to a chemical agent release **
**All persons who anticipate being active in potentially hazardous environments as part of CSEPP emergency response plan **
**Before training, a medical evaluation shall be performed**
**Regular drills and training sessions designed to maintain familiarity with equipment should be incorporated into emergency response protocols**

## What is PPE?

**Personal Protective Equipment (PPE) is defined as articles worn or equipment used in order to protect wearer from harmful contaminants in environment**
**Main function of PPE is to provide****shield between you and agent contaminating environment**
**To be effective it must****prevent you from being****contaminated by airborne****or surface agents**

## Proper Use Critical

***If PPE must be used, it must be used correctly***
**It is not possible to be partially protected from nerve or blister agents; **_**you are either protected or not protected**_

## Potential nerve and blister agent contamination requires respiratory protection and protective covering for all parts of the body.  Includes:
Powered air-purifying respirator (PAPR)
Hood
Protective suit
Overshoes
Gloves
Apron (if needed)
This type of protection guards againstskin, respiratory tract, and eye exposures

**Powered air-purifying respirator (PAPR)**
**Hood**
**Protective suit**
**Overshoes**
**Gloves**
**Apron (if needed)**
**This type of protection guards against****skin, respiratory tract, and eye exposures**

**Recommended PPE**

## CSEPP, in conjunction with theCenters for Disease Control and Prevention/National Center for Environmental Health, have conducted several studies and tests on PPE to select the appropriate PPE for CSEPP

**CSEPP Protective Clothing**

## Availability of PPE

**This equipment is only to be used in the event that an accident or incident involving chemical weapon agents has occurred**
**Protective suit, hood, gloves, overshoes, PAPR, and apron (if appropriate) will be kept available in Ready Bag for designated emergency responders **
**Backup and training suits will also be made available**
**Upon termination from CSEPP, worker shall return protective suit, hood, gloves, apron, overshoes, Ready Bag, and PAPR as outlined in State and local plans**

## Protective Suit

**4 suits approved for CSEPP use**
**Only 2 suits being used by CSEPP Communities**
**DuPont/Kappler Responder**
**DuPont/Kappler CPF3**
**This course focuses on the 2 suits being used**

## DuPont/Kappler Responder and CPF 3 Suits

**One-piece coverall suits for wear over street clothes or long underwear**
**Multiple layer, composite material provides protection**
**Responder weighs less; CPF 3 is tougher**
**Do not protect from heat and cold**

## DuPont/Kappler Responder and CPF3 Suits

**Store on hangers or in shipping bag**
**Shelf life of 5 years**
**Not repairable; discard if damaged or worn out**
**Discard after exposure to chemical agent**

## Outer glove for protection and inner glove for perspiration absorption
Outer gloves impermeable, black, butyl rubber
Inner gloves thin, white cotton
Protect against liquid chemicalagents and vapor hazards
If become contaminated,replace within 24 hours 
Replace if exposed to anypetroleum-based products

**Outer gloves impermeable, black, butyl rubber**
**Inner gloves thin, white cotton**
**Protect against liquid chemical****agents and vapor hazards**
**If become contaminated,****replace within 24 hours **
**Replace if exposed to any****petroleum-based products**

**Gloves**

## Overshoes

**Military-issue vinyl overshoes with elastic fasteners**
**Protect feet from contamination by all known agents for up to 24 hours following****contamination; for up to 14 days if not contaminated**

## Apron

**Only those performing decontamination tasks need to wear aprons**
**Wrap-around style, made of a front panel, two side panels, and raglan sleeves**
**Designed to fit loosely and cover the wearer's arms and body from overshoes to neck**
**Nylon cloth, coated with butyl rubber on both sides**

## Ready Bag

**Canvas bag designed to carry all the protective equipment (protective suit, hood, gloves, apron, overshoes, PAPR, and detection kits)**

## Respiratory Equipment

**Prevents airborne contaminants from being inhaled**
**Protects facial skin from exposure**
**Must be only used in context of complete respirator program as described in OSHA regulations and NIOSH publications **

## Powered Air-Purifying Respirator (PAPR)

**Protects against**
**particulates**
**gases and vapors**

## PAPR Components

**2 types of PAPR are approved for CSEPP**
**Tight-fitting PAPR**
**Loose-fitting PAPR**
**Tight-fitting PAPR provides better respiratory protection**
**Loose-fitting PAPR is easier to use; accommodates facial hair and eyeglasses**
**Tight-fitting provides protection if batteries fail, while loose-fitting must be removed**

## PAPR Components

**Both types of PAPRs consist of **
**Full facepiece**
**Butyl rubber-covered hood**
**Breathing tube**
**Motor-blower unit with filter cartridges**
**Battery**

## Powered Air-Purifying Respirator (PAPR)

**Battery-operated blower delivers decontaminated air at slight positive pressure into full facepiece **
**If leak occurs, air will flow from inside facepiece to outside air**
**Draws outside air through filters which remove                 contaminants and delivers the cleaned                       air through corrugated breathing                        tube into facepiece assembly on face                     of wearer**
**Air flow also provides wearer comfort**

## Why the PAPR Was Selected

**Civilian air-purifying respirators approved by CDC/NCEH **
**NIOSH confirmed cartridge tests were conducted in valid scientific manner **
**Data support conclusion that commercial cartridges tested will remove up to 0.5 milligram per cubic meter of nerve agent GB for up to 16 hours**
**Concentration chosen because maximum predicted concentration to which emergency worker would be exposed **
**U.S. Army data on military gas masks indicate that nerve agent GB wears out filters more quickly than other agents **** **

## Spectacle Kit

**Proper seal with tight-fitting PAPR cannot be established if the temple bars of eyeglasses extend through sealing edge of full facepiece **
**3M has developed spectacle kits that mount corrective lenses inside full facepieces**
**Personnel who wear eyeglasses should use a spectacle kit or wear a loose-fitting PAPR**

## Limitations of PAPRS

**Do NOT use in atmospheres immediately dangerous to life or health (IDLH)**
**Do NOT use in atmospheres containing less than 19.5% oxygen (confined spaces)**
**Do NOT use the respirators in a flammable or explosive atmosphere**
**Do NOT use air-purifying elements beyond useful life**
**Use only fully charged battery packs when respirator is donned**
**Protect batteries/battery packs from fire and heat at all times**

## Air-Purifying Cartridges

**Most common filtration method for airborne particulates**
**Often referred to as filter or canister**
**Always read cartridge labels**
**All cartridges in blower unit must be identical and must be replaced at same time**
**Follow good industrial hygiene practices when replacing and disposing of cartridges **

## Identify cartridge by properly worded labels and  color code
Correct color code for organic vapor is black 
In each Ready Bag:   
3 sets of 3 cartridges
1 set for chemical accident/ incident 
1 set for backup
1 set for training marked “For Training Purposes Only”

**Correct color code for organic vapor is **_**black **_
**In each Ready Bag: ****  **
**3 sets of 3 cartridges**
**1 set for chemical accident/ incident **
**1 set for backup**
**1 set for training marked ****“For Training Purposes Only”**

**Cartridges**

## Respirator Fit Testing

**Shall be done while wearing all protective equipment that could interfere with fit and/or wearer acceptance**
**Must be based upon 29 CFR 1910.134 Appendix A**
**Must be repeated at least annually based on    29 CFR 1910.134(f) **
**Medical evaluation required for wearer**
**You should be familiar with State and local requirements**

##  Storage of PPE

**Before storing the facepiece, it should be**
**Inspected**
**Repaired, if necessary**
**Cleaned**
**Dried**
**Given final inspection**

**RESPIRATOR**

## Storage of PPE

**After preparing facepiece for storage: **
**Place facepiece in closed plastic bag**
**Bag and facepiece should be stored away from sunlight and direct heat**
**Store in clean, dry, cool place that is free from contaminating vapors, gases and particulates**
**Storage temperatures must not exceed ****120°F (49°C)****—don’t store in vehicle!**
**Bag should be clearly labeled to indicate type of facepiece**

**RESPIRATOR**

## Storage of PPE

**While in storage, facepiece should be protected from distortion from weight or pressure of surrounding objects or being placed in too small a place**
**NEVER store PPE equipment in car or truck because of potential for heat damage but in a location easily accessible**
**Fully charged battery pack should be stored in closed plastic bag in dry, cool place where atmosphere is uncontaminated**
**When sold, battery pack is not charged**

**RESPIRATOR**

## Storage of PPE

**Use battery charger and AC/DC adapter to charge and recharge battery pack**
**All parts in plastic bag should be connected together in manner of assembled respirator**
**Facepiece and its subparts should be stored separately from remainder of PAPR**
**Only fully operable facepieces should be stored**

**RESPIRATOR**

## Storage of PPE

**Storage of PPE**

**PROTECTIVE CLOTHING**
**DuPont/Kappler Responder and CPF3 protective suits come sealed in a shipping bag    **
**The protective suit may be stored in the open shipping bag inside the Ready Bag along with, gloves, hood, overshoes, and apron **
**Alternatively, the suits can be stored on hangers **
**Store:**
**away from sunlight and direct heat**
**in a clean, dry, cool place that is free from contaminating vapors, gases and particulates**
**storage temperatures must not exceed 120°F (49°C) **

## Basis For Work Rules

**CSEPP off-site emergency workers will not conduct aggressive spill containment or cleanup operations**
**Modification of established State and local response plans may be required**
**Basis of modifications will include**
**Technical information developed by Army over last 30 years about potential threat from chemical weapon agents**
**Ergonomic considerations**
**Capabilities of PPE to provide protection**

## State and Local Government Decisions 

**      ****Option 1 – Emergency workers must wear PPE when they enter any area where protective actions have been determined for public.**
**Includes traffic control, decontamination stations, and emergency medical responders who assist in implementation of protective actions**
**Will preclude emergency  workers from being exposed to chemical agent without PPE**** **
**      ****Option 2 – Emergency workers wear PPE when they enter any area where accident conditions indicate chemical agent may be present as vapor or deposited on the ground.**
**Would require PPE only where agent believed to be present, thus minimizing risk of heat stress to emergency workers where public protective actions are precautionary rather than based on projected exposure**

## Basis And Timing For Working In PPE 

**Emergency workers who enter an area where PPE is required must limit their activities so that protection from contamination and excessive exposure is assured**

## Basis And Timing For Working In PPE 

_**Not**_** be sent into environments which are known or suspected to be immediately dangerous to life or health (IDLH)**
_**Not**_** remain in potentially contaminated area long enough to receive agent dosage sufficient to affect health or ability to execute assigned tasks**
_**Not**_** remain in potentially contaminated area long enough to exceed agent absorption capacity of canisters used in PAPR**
_**Not**_** be exposed to agent deposition density levels exceeding maximum capability of protective suit**

**This requires that emergency workers**** **

## Airborne Agent ConcentrationsImmediately Dangerous to Life or Health (IDLH)

**GA/GB****	****	****	****0.2**
**VX****	****	****	****0.02**
**HD/L****	****	****	*******

***The U.S. Army Environmental Hygiene Agency proposed a value of 1.67 mg/m****3****.  However, as of this date, the Office of the U.S. Army Surgeon General has not formally established IDLH levels for HD or L.**

**Agent****	****Concentration (mg/m****3****)**

**Airborne Agent Concentrations****Immediately Dangerous to Life or Health (IDLH)**

## Exposure Limits

**Simplest, most effective work rule to assure that respirator cartridges are used within capacity is to avoid sending emergency workers into areas where a plume containing airborne chemical agent my be present**
**Activity of off-site emergency workers in areas where airborne chemical agent may be present must be limited**
**To ensure that workers are not exposed to average airborne agent concentrations greater than those established for agent workers, even when using respiratory protection**
**To ensure that agent absorption capacity of respirator cartridges is not exceeded**

## Respirator Cartridge Limits

**Have been determined to provide at least 16 hours of protection when exposed to an agent vapor concentration of 0.5 mg/m****3**
**Possible that under certain release and atmospheric conditions this dosage may be exceeded outside boundaries of several storage installations**

## Respirator Cartridge Limits

**Work rules must avoid possibility that emergency workers can be exposed to conditions in excess of cartridge’s absorption capacity**
**Once airborne agent concentration level has declined below IDLH level, combination of limited stay times and use of chemical detector kits can assist emergency workers in using PPE within its capabilities**

## PAPR-Limited Stay Times

**Depend on**
**Concentration of chemical agent in the air**
**Exposure limit for the chemical agent**
**The protection factor for the respirator**
**The dosage capacity of the filter cartridges**

## Work Intensity

**Along with ambient temperature, work intensity is major contributing factor to heat stress **
**Work/rest cycles should be instituted to control heat stress. Cycles need to be flexible because of **
**Variability in work intensity**
**Differences in individuals susceptibility to heat stress**
**Unique demands of each emergency situation**

## Clothing-Limited Stay Times

**COOL TEMPERATURES**
**50 – 70°F (10 – 21°C) [Wet Bulb/Globe Temperature (WBGT)]**
**Work 30 – 45 minutes**
**Followed by 10 –15 minutes rest**
**WARM TEMPERATURES**
**70 – 85°F (21 – 29°C) [Wet Bulb/Globe Temperature (WBGT)]**
**Work 20 – 30 minutes**
**Followed by 40 – 60 minutes rest**
**HOT TEMPERATURES**
**85 – 100°F (29 – 38°C) [Wet Bulb/Globe Temperature (WBGT)]**
**Work 15 – 20 minutes**
**Followed by indefinite rest**

**PPE60**

## Heat Stress Factors

**PPE restricts heat loss mechanisms because of low permeability to water vapor**
**Amount of heat accumulation depends upon**
**Amount of physical activity**
**Level of hydration**
**Clothing worn**
**Load carried**
**State of heat acclimatization**
**Physical fitness and fatigue**
**Terrain and climatic conditions**

## Dehydration

**Because of higher body temperatures, individuals in PPE sweat considerably more than usual, often more than 1.5 quarts of water every hour during work**
**Water must be consumed to replace lost fluids or dehydration will follow**
**Inability to drink in full PPE increases likelihood of dehydration**
**Dehydration and need for regular and timely fluid replacement in workers is limiting factor on stay time in full PPE**

## Psychological Factors

**Wearing full PPE reduces ability to see and hear clearly**
**Makes it more difficult to recognize and communicate with others**
**Creates or increases feelings of isolation and confusion**
**Causes frustration in many and claustrophobia in others**
**Experience in wearing and exercising in PPE can reduce these feelings**

## Workers wearing PPE will take about 1.5 times longer to perform most tasks
Performance is affected by stress in a variety of ways:
Reaction times and decision times are longer
Routine tasks are done more slowly
Errors of omission are more common
Use the buddy system whenever possible; a buddy can check for signs of stress and fatigue
Critical jobs should be shared and work should be double-checked

**Critical jobs should be shared and work should be double-checked**

**Effects of Heat Stress on Performance in PPE**

## Cold Stress Factors

**Can directly affect an individual’s health and performance while wearing PPE**
**Can lower body temperature, resulting in cold injuries and impaired performance**
**Often accompanied by wind, rain, snow and ice, which can worsen the effects of cold**
**Cold weather clothing and PPE are difficult to integrate**

## Buddy System Recommended

**Good industrial hygiene practice recommends buddy system be used if resources permit**
**Can assist other workers in dressing out in PPE**
**Can ensure that all workers are regularly checked for signs of stress and agent exposure**
**Pair an experienced worker with inexperienced “buddy” whenever possible**

## Work Rules Summary

_**Plan Ahead**_
**Follow guidance for working in PPE**
**Ensure serviceability of equipment through regular inspections of PPE equipment**
**Plan work/rest cycles appropriate to environment and situation**
**Use standard operating procedures to reduce command, control, and communication tasks**
**Keep plans and operations simple**

## Work Rules Summary

**Use methods of individual identification **
**Encourage small talk while in PPE**
**If resources permit, use the buddy system to ensure that all workers are regularly checked for signs of stress and agent exposure**
**Pair experienced worker with inexperienced “buddy” whenever possible**

_**Think Teamwork**_

## Work Rules Summary

**Provide relief from PPE outside hazard area as soon as situation allows**
**Use work/rest ratios, slow work rate, and minimize work intensity**
**Work in the shade whenever possible**
**Rotate jobs and people during long periods of relative inactivity**
**Provide relief from extreme temperatures (hot or cold) as soon as possible**
**Remember that even short breaks from total encapsulation are effective in sustaining performance**
**Enforce drinking of water to reduce dehydration and heat casualties**
