Section 4. First aid measures
Prompt medical attention is mandatory in all cases of overexposure to this gas. Rescue personnel should wear a
self-contained breathing apparatus.
: In case of inhalation, conscious persons should be assisted to an uncontaminated area
Inhalation
and inhale fresh air. The person should be kept warmed and calm. Quick removal from
the contaminated area is most important. Unconscious persons should be moved to an
uncontaminated area, given assisted resuscitation and supplemental oxygen. Further
treatment should be symptomatic and supportive.
: Remove contaminated clothing and rinse affected skin with lukewarm water. Do not
Skin contact
rinse with hot water. Provide medical prompt attention, frozen tissue is painless and
appear waxy, with a possible yellow color. Frozen tissue will become swollen, painful
and prone to infection when thawed.
: Individual in contact with a gas should not wear contact lenses. Check for and remove
Eye contact
any contact lenses. In case of contact, immediately flush eyes with plenty of water for at
least 20 minutes. Get medical attention if symptoms occur.
: Since the product is a gas, it will probably be inhaled rather than ingested. Consider first

the preventive measures in case of inhalation.
: The medical doctor must be warned that the person may suffer from anoxia.
Notes to physician
Section 5. Fire fighting measures
: Non-flammable.
Flammability of the product
: Decomposition products may include the following materials:
Products of combustion
nitrogen oxides
: Container explosion may occur under fire conditions or when heated.
Explosion hazards in the
presence of various
substances
: Use an extinguishing agent suitable for the surrounding fire.
Fire-fighting media and
instructions
Contains gas under pressure. Contact with combustible material may cause fire. This
material increases the risk of fire and may aid combustion. In a fire or if heated, a
pressure increase will occur and the container may burst or explode.
: Fire-fighters should wear appropriate protective equipment and self-contained breathing
Special protective
apparatus (SCBA) with a full face-piece operated in positive pressure mode.
equipment for fire-fighters
Section 6. Accidental release measures
: EVACUATE ALL PERSONNEL FROM AFFECTED AREA.
Personal precautions
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 Canada location.
: Ensure emergency procedures to deal with accidental gas releases are in place to avoid

contamination of the environment. Inform the relevant authorities if the product has
caused environmental pollution (sewers, waterways, soil or air).
: Immediately contact emergency personnel. Stop leak if without risk. Use spark-proof

Section 7. Handling and storage
: Valve protection caps must remain in place unless cylinder is secured with valve outlet
Handling
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.
: Protect cylinders from physical damage. Store in cool, dry, well-ventilated area of non
Storage
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. Use a "first in - first out" inventory system to
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.
Section 8. Exposure controls/personal protection
: Use only in well-ventilated areas. Gas may accumulate in confined areas.
Engineering controls
Personal protection
: Respirator selection must be based on known or anticipated exposure levels, the
Respiratory
hazards of the product and the safe working limits of the selected respirator.
: Wear suitable gloves for the application.
Hands
: Safety glasses with side shields.
Eyes
: Wear appropriate personal protective suit.
Skin/Body
Metal cap, safety shoes are recommended when handling cylinders.
Some applications of this product may require additionnal or other specific protective clothings. Please consult
your supervisor.
Personal protection in case : Safety glasses, goggles or face shield. Impervious gloves. Full suit. Metal cap, safety
boots. Wear MSHA/NIOSH-approved self-contained breathing apparatus or equivalent
of a major leak
and full protective gear.
