Suitable extinguishing media : All known extinguishing media can be used. 

Specific hazards : Upon exposure to intense heat or flame, cylinder will vent rapidly and or rupture 

violently. Product is nonflammable and does not support comb ustion. Move 

away from container and cool with water from a protected position. If possible, 

stop flow of product. Keep adjacent cylinders cool by spraying with large 

amounts of water until the fire burns itself out. Most cylinders are designed to 

vent contents when exposed to elevated temperatures. 

Special protective equipment 

for fire-fighters 

: Wear self contained breathing apparatus for fire fighting if necessary. 

6. ACCIDENTAL RELEASE MEASURES 

Personal precautions : Monitor carbon dioxide level. Evacuate personnel to safe areas. Wear 

self-contained breathing apparatus when entering area unless atmosphere is 

proved to be safe. Ventilate the area. Monitor oxygen level. 

Environmental precautions : Should not be released into the environment. Do not discharge into any place 

where its accumulation could be dangerous. Prevent further leakage or spillage. 

Prevent from entering sewers, basements and workpits, or any place where its 

accumulation can be dangerous. 

Methods for cleaning up : Ventilate the area. 

Additional advice : If possible, stop flow of product. Increase ventilation to the release area and 

monitor oxygen level. If leak is from cylinder or cylinder valve, call the Air 

Products emergency telephone number. If the leak is in the user's system, close 

the cylinder valve, safely vent the pressure, and purge with an inert gas before 

attempting repairs. 

7. HANDLING AND STORAGE 

Handling 

Only experienced and properly instructed persons should handle compressed gases/cryogenic liquids. Protect 

cylinders from physical damage; do not drag, roll, slide or drop. Do not allow storage area temperature to exceed 

50°C (122°F). Before using the product, determine i ts identity by reading the label. Know and understand the 

properties and hazards of the product before use. When doubt exists as to the correct handling procedure for a 

particular gas, contact the supplier. Do not remove or deface labels provided by the supplier for the identification of 

the cylinder contents. When moving cylinders, even for short distances, use a cart (trolley, hand truck, etc.) 

designed to transport cylinders. Leave valve protection caps in place until the container has been secured against 

either a wall or bench or placed in a container stand and is ready for use. Use an adjustable strap wrench to 

remove over-tight or rusted caps. Before connecting the container, check the complete gas system for suitability, 

particularly for pressure rating and materials. Before connecting the container for use, ensure that back feed from 

the system into the container is prevented. Ensure the complete gas system is compatible for pressure rating and 

materials of construction. Ensure the complete gas system has been checked f or leaks before use. Employ 

suitable pressure regulating devices on all containers when the gas is being emitted to systems with lower 

pressure rating than that of the container. Never insert an object (e.g. wrench, screwdriver, pry bar, etc.) into valve 

cap openings. Doing so may damage valve, causing a leak to occur. Open valve slowly. If user experiences any 

difficulty operating cylinder valve discontinue use and contact supplier. Close container valve after each use and 

when empty, even if still connected to equipment. Never attempt to repair or modify container valves or safety

relief devices. Damaged valves should be reported immediately to the supplier. Close valve after each use and 

when empty. Replace outlet caps or plugs and container caps as soon as container is disconnected from 

equipment. Do not subject containers to abnormal mechanical shocks which may cause damage to their valve or 

safety devices. Never attempt to lift a cylinder by its valve protection cap or guard. Always use backflow protective 

device in piping. When returning cylinder install valve outlet cap or plug leak tight. Never use direct flame or 

electrical heating devices to raise the pressure of a container. Containers should not be subjected to temperatures 

above 50°C (122°F). Prolonged periods of cold tempe rature below -30°C (-20°F) should be avoided. Never

attempt to increase liquid withdrawal rate by pressurizing the container without first checking with the supplier. 

Never permit liquefied gas to become trapped in parts of the system as this may result in hydraulic rupture. 

Storage

Full containers should be stored so that oldest s tock is used first. Containers should be stored in the vertical 

position and properly secured to prevent toppling. The container valves should be tightly closed and where 

appropriate valve outlets should be capped or plugged. Container valve guards or caps should be in place. 

Observe all regulations and local requirements regarding storage of containers. Stored containers should be 

periodically checked for general condition and leakage. Protect containers stored in the open against rusting and 

extremes of weather. Containers should not be stored in conditions likely to encourage corrosion. Containers 

should be stored in a purpose build compound which should be well ventilated, preferably in the open air. Keep 

containers tightly closed in a cool, well-ventilated place. Store containers in location free from fire risk and away 

from sources of heat and ignition. Full and empty cylinders should be segregated. Do not allow storage

temperature to exceed 50°C (122°F). Return empty co ntainers in a timely manner. 

Technical measures/Precautions 

Containers should be segregated in the storage area according to the various categories (e.g. flammable, toxic, 

etc.) and in accordance whit local regulations. Keep away from combustible material. 

8. EXPOSURE CONTROLS / PERSONAL PROTECTION 

Engineering measures 

Provide natural or mechanical ventilation to prevent accumulation above exposure limits.

Provide natural or mechanical ventilation to prev ent oxygen deficient atmospheres below 19.5% oxygen.

Personal protective equipment 

Respiratory protection : Self contained breathing apparatus (SCBA) or positive pressure airline with mask 

are to be used in oxygen-deficient atmosphere. 

 Air purifying respirators will not provide protection. Users of breathing apparatus 

must be trained. 

Hand protection : Sturdy work gloves are recommended for handling cylinders.

The breakthrough time of the selected glove(s) must be greater than the intended 

use period.

Eye protection : Safety glasses recommended when handling cylinders.

Skin and body protection : Safety shoes are recommended when handling cylinders.
