FLAMMABLE GAS MIXTURE Effective Date:03/15/2007
Page: 2/7
5. Fire-fighting measures
(Suitable) Use water, carbon dioxide, dry chemicals or foam. Move containers from fire
area if this can be done without risk. Fight fire from protected location or
maximum possible distance. Cool containing vessels with flooding quantities
of water until well after fire is out.
(Unsuitable) None known.
Unusual fire/explosion hazards Contains gas under pressure. In a fire or if heated, a pressure increase will
occur and the container may burst or explode.
Special fire-fighting procedures Not applicable.
6. Accidental release measures
Personal precautions EVACUATE ALL PERSONNEL FROM AFFECTED AREA.
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.
Environmental precautions In case of a leak, clear the affected area, protect people, eliminate sources
of ignition and respond with trained personnel. Adequate fire protection must
be provided.
If leaking incidentally from the cylinder or its valve, contact your supplier.
Use non-sparking tools and equipment during the response.
Methods for cleaning up Contact your local Air Liquide Gas supplier for details.
Other information Not available.
7. Handling and storage
Hygiene measures Wash hands, forearms and face thoroughly after handling chemical
products, before eating, smoking and using the lavatory and at the end of the
working period. Appropriate techniques should be used to remove potentially
contaminated clothing. Wash contaminated clothing before reusing. Ensure
that eyewash stations and safety showers are close to the workstation
location.
Be aware of any signs of dizziness or fatigue; exposures to fatal
concentrations of this gas mixture could occur without any significant warning
symptoms; due to oxygen deficiency.
Handling To avoid fire, eliminate ignition sources. Use explosion-proof electrical
equipment (ventilating, lighting and material handling). 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 the cylinder. Do
not tamper with (valve) safety device. Close valve after each use and when
empty.
Storage Protect cylinders from physical damage. Store in cool, dry, well-ventilated
area of non combustible construction away from heavily trafficked areas and
emergency exits. Do not allow the temperature where cylinders are stored to
exceed 52癈/125癋. Cylinders must be stored upright and firmly secured to
prevent falling or being knocked over. Full and empty cylinders should be
segregated. 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.
Segregate from oxidizing materials.

8. Exposure controls and personal protection
Engineering controls Use only in well-ventilated areas.
Respiratory protection Maintain oxygen levels above 19.5% in the workplace. 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 mixture. 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.
Eye protection Safety glasses with side shields.
Hand protection. Wear leather gloves when handling cylinders of this gas mixture. Otherwise,
wear glove protection appropriate to the specific operation for which this gas
mixture is used. Liquid or rapidly evolving gas can cause burns similar to
frostbite.
Skin protection 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 clothing.
Exposure limits See Section 3.
