2. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: Air is a colorless, odorless gas. The main health hazards associated with exposure
to this gas are related to the high pressure. Contact with rapidly expanding gases from a cylinder that is suddenly
released can cause frostbite to exposed skin or damage to eyes. Air is generally considered non-flammable,
however, Air will support combustion. A moderate cylinder rupture hazard exists when Air, which is under
pressure, is subject to heat or flames.

2. HAZARD IDENTIFICATION (Continued)
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The most significant route of over-exposure for
air is by inhalation at elevated or reduced pressure.
INHALATION: Air is non-toxic and necessary to support life. Inhalation of Air in high pressure environments, such
as underwater diving or hyperbolic chambers can result in symptoms similar to over-exposure to pure oxygen.
These symptoms include tingling of the fingers and toes, abnormal sensations, along with impaired coordination and
confusion. Decompression sickness, 鈥渂ends鈥?, is possible following rapid decompression.
CONTACT WITH SKIN or EYES: Contact with rapidly expanding gases (which are released under high pressure)
may cause frostbite. Symptoms of frostbite include change in skin color to white or grayish-yellow. The pain after
contact with liquid can quickly subside. Contact with the rapidly expanding vapors released the high pressure
cylinder may cause freezing of the eye. Permanent eye damage or blindness could result.
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Over-exposure to Air may
cause the following health effects:
ACUTE: The most significant hazards associated with air is the pressure hazard.
CHRONIC: There are currently no known adverse health effects associated with chronic exposure to this gas.
TARGET ORGANS: ACUTE: None. CHRONIC: None.

4 FIRST-AID MEASURES
As the opportunity for injury from exposure to Air is limited to inhalation of Air in high pressure environments, such as
underwater diving or hyperbolic chambers, the first-aid measures would be for over-pressure accidents, or rapid
decompression-induced decompression sickness. In the event of such accidents, seek immediate and qualified
medical attention.
In case of frostbite, place the frostbitten part in warm water. DO NOT USE HOT WATER. If warm water is not
available, or is impractical to use, wrap the affected parts gently in blankets. Alternatively, if the fingers or hands are
frostbitten, place the affected area of the body in the armpit. Encourage victim to gently exercise the affected part
while being warmed. Seek immediate medical attention.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: A knowledge of the available information suggest that
over-exposure to Air is unlikely to aggravate existing medical conditions.
RECOMMENDATIONS TO PHYSICIANS: Treat symptoms and reduce over-exposure if air is breathed in high
pressure environment, (i.e. illness associated with decompression, bends, or caisson disease). Decompression
equipment may be required.

FLASH POINT: Not applicable.
AUTOIGNITION TEMPERATURE: Not applicable.
FLAMMABLE LIMITS (in air by volume, %):
Lower (LEL): Not applicable.
Upper (UEL): Not applicable.
FIRE EXTINGUISHING MATERIALS: Non-flammable. Air will support combustion of flammable materials. Use
extinguishing media appropriate for surrounding fire.
Water Spray: YES Carbon Dioxide: YES Dry Chemical: YES
Halon: YES Foam: YES Other: Any "ABC鈥? Class.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Air does not burn; however, cylinders, when involved in fire, may
rupture or burst in the heat of the fire.
Explosion Sensitivity to Mechanical Impact: Not Sensitive.
Explosion Sensitivity to Static Discharge: Not Sensitive.
SPECIAL FIRE-FIGHTING PROCEDURES: Incipient fire responders should wear eye protection. Structural fire-
fighters must wear Self-Contained Breathing Apparatus and full protective equipment. If possible, shut-off the flow of
Compressed Air supporting the fire. Immediately cool the cylinders with water spray from maximum distance. When
cool, move cylinders from fire area, if without risk.
6. ACCIDENTAL RELEASE MEASURES
LEAK RESPONSE: Uncontrolled releases should be responded to by trained personnel using pre-planned
procedures. Proper protective equipment should be used. In case of a release, clear the affected area, protect
people, and respond with trained personnel. Minimum Personal Protective Equipment should be Level D: safety
glasses. Locate and seal the source of the leaking gas. If this does not stop the release (or if it is not possible to
reach the valve), allow the gas to release in-place or remove it to a safe area and allow the gas to be released there.
If leaking incidentally from the cylinder or its valve, contact your supplier.
7. HANDLING AND STORAGE
WORK PRACTICES AND HYGIENE PRACTICES: Air intended for breathing must conform to CGA Standard G-7
(Compressed Air for Human Respiration) and Standard G-7.1, American National Standard Commodity
Specification for Air. All other sources of compressed air must be treated as unfit for human consumption until
tested for conformance with these standards.
STORAGE AND HANDLING PRACTICES: Compressed gases can present significant safety hazards. Store
cylinders away from heavily trafficked areas and emergency exits. Post 鈥淣o Smoking or Open Flames鈥? signs in
storage or use areas.
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: Protect cylinders against physical damage. Store
in cool, dry, well-ventilated, fireproof area, away from flammable or combustible materials and corrosive
atmospheres. Store away from heat and ignition sources and out of direct sunlight. Do not store near elevators,
corridors or loading docks. Do not allow area where cylinders are stored to exceed 52 掳C (125 掳F). Isolate from
incompatible materials including flammable materials. (see Section 10, Stability and Reactivity) for more information),
which can burn violently. Use only storage cylinders and equipment (pipes, valves, fittings to relieve pressure, etc.)
designed for the storage of Air. Do not store cylinders where they can come into contact with moisture. Cylinders
should be stored upright and be firmly secured to prevent falling or being knocked over. Cylinders can be stored in
the open, but in such cases, should be protected against extremes of weather and from the dampness of the ground
to prevent rusting. Never tamper with pressure relief devices in valves and cylinders. The following rules are
applicable to situations in which cylinders are being used:
Before Use: Move cylinders with a suitable hand-truck. Do not drag, slide or roll cylinders. Do not drop cylinders
or permit them to strike each other. Secure cylinders firmly. Leave the valve protection cap in-place (where
provided) until cylinder is ready for use.
During Use: Use designated CGA fittings and other support equipment. Do not use adapters. Do not heat
cylinder by any means to increase the discharge rate of the product from the cylinder. Use check valve in
discharge line to prevent hazardous backflow into the cylinder. Do not use oils or grease on gas-handling fittings or
equipment.
After Use: Close main cylinder valve. Replace valve protection cap (where provided). Mark empty cylinders
鈥淓MPTY鈥?.
NOTE: Use only DOT or ASME code cylinders. Close valve after each use and when empty. Cylinders must not
be recharged except by or with the consent of owner.

For Routine Industrial Use and Handling Applications
Atmospheric air that is compressed is composed of the following gases:
Nitrogen: 78%
Oxygen 21%
Argon 0.9%
Compressed air is also synthetically produced by mixing 79% nitrogen and 21% oxygen.
MIXTURES: When two or more gases or liquefied gases are mixed, their hazardous properties may combine to
create additional, unexpected hazards. Obtain and evaluate the safety information for each component before
you produce the mixture. Consult an Industrial Hygienist or other trained person when you make your safety
evaluation of the end product. Remember, gases and liquids have properties which can cause serious injury or
death.
