Contains gas under pressure. In a fire or if heated, a pressure increase will occur and
the container may burst or explode.
Special protective
equipment for fire-fighters
Fire-fighters should wear appropriate protective equipment and self-contained breathing
apparatus (SCBA) with a full face-piece operated in positive pressure mode.
Use appropriate protective equipment. If leak is in user's equipment, be certain to purge
piping with an inert gas prior to attempting repairs. If leak is on cylinder or cylinder valve,
contact the closest Air Liquide location.
Contact your local Air Liquide Gas supplier for details.
Environmental precautions
Section 6. Accidental release measures
In case of a leak, clear the affected area, protect people, eliminate sources of ignition
and respond with trained personnel.
If leaking incidentally from the cylinder or its valve, contact your supplier. Use non-
sparking tools and equipment during the response.
Personal precautions
Methods for cleaning up
Protect cylinders from physical damage. Store in cool, dry, well-ventilated area of non
combustible construction away from heavy traffic areas and emergency exits. Do not
allow the temperature where cylinders are s tored to exceed 52C/125F. Cylinders must
be stored upright and firmly secured to prevent falling or being knocked over. Full and
empty cylinders should be segregated. Prevent full cylinders being stored for excessive
periods of time. Post "No Smoking or Open Flames" signs in the storage or use area.
There should be no source of ignition in the storage or use area.
Valve protection caps must remain in place unless cylinder is secured with valve outlet
piped to usage point. Do not drag, slide or roll cylinders. Use a suitable hand truck for
cylinder movement. Use a pressure regulator when connecting cylinder to lower
pressure piping or systems. Do not heat cylinder by any means to increase the discharge
rate of product from the cylinder. Use a check valve or trap in the discharge line to
prevent hazardous back flow to the cylinder. Do not tamper with (valve) safety device.
Close valve after each use and when empty.
Section 7. Handling and storage
Use only in well-ventilated areas. Gas is heavier than air and will therefore accumulate in
low lying areas.
Section 8. Exposure controls/personal protection
Engineering controls
Maintain oxygen levels above 19.5% in the work place. Use supplied air respiratory
protection if oxygen levels are below 19.5% (air purifying respirators will not function) or
during emergency response to a release of this gas. During an emergency situation,
before entering the area, check for oxygen-deficient atmospheres. If respiratory
protection is required, follow the requirements of the Federal OSHA Respiratory
Protection Standard (29 CFR 1910.134), or equivalent State standard.
Safety glasses with side shields.
Use body protection appropriate for task . Cotton clothing is recommended for use to
prevent static electric build-up. Pressurized product may require use of fire retardant
Personal protection
Wear leather gloves when handling cylinders of this gas. Otherwise, wear glove
protection appropriate to the specific operation for which this gas is used.
Metal cap, safety shoes are recommended when handling cylinders.
