IARC, or OSHA.
SECTION 4. FIRST AID MEASURES
EYE CONTACT: Not applicable
INHALATION: Not applicable
SKIN CONTACT: Not applicable
NOTES TO PHYSICIAN: None
SECTION 5. FIRE FIGHTING MEASURES
FLASH POINT: AUTOIGNITION: FLAMMABLE RANGE:
Not applicable Not applicable Nonflammable
EXTINGUISHING MEDIA: Product is nonflammable, but will support combustion. Use
extinguishing media appropriate for surrounding fire.
SPECIAL FIRE FIGHTING INSTRUCTIONS: Evacuate all personnel from area. If possible, shut
off flow of air which is supporting the fire. If possible, remove cylinders from fire area or cool with
water. SCBA may be required by rescue workers.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Compressed air at high pressures may
accelerate combustion. Most cylinders are designed to vent contents when exposed to elevated
temperatures. Pressure in a cylinder can build up due to heat and it may rupture if pressure relief
devices should fail to function.
HAZARDOUS COMBUSTION PRODUCTS: None
SECTION 6. ACCIDENTAL RELEASE MEASURES
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: Evacuate immediate area.
Shut off source of leak if possible. Isolate any leaking cylinder. If leak is from container, pressure
relief device or its valve, contact your supplier. If leak is in user s system, close cylinder valve,
safely vent pressure before attempting repairs.
SECTION 7. HANDLING AND STORAGE
STORAGE: Store cylinders in a well-ventilated, secure area, protected from the weather.
Cylinders should be stored upright with valve outlet seals and valve protection caps in place. Do
not allow storage temperature to exceed 125 掳 F (52 掳 C). Storage should be away from heavily
traveled areas and emergency exits. Full and empty cylinders should be segregated. Use a first-
in, first-out inventory system to prevent full containers from being stored for long periods of time.
HANDLING: Do not drag, roll, slide or drop cylinder. Use a suitable hand truck designed for
cylinder movement. Never attempt to lift a cylinder by its cap. Secure cylinders at all times. Use a
pressure reducing regulator to safely discharge gas from cylinder. Use a check valve to prevent
reverse flow into cylinder. Use piping and equipment adequately designed to withstand pressures
to be encountered. Never apply flame or localized heat directly to any part of the cylinder. Do not
allow any part of the cylinder to exceed 125 掳 F (52 掳 C). Once cylinder has been connected to
process, open cylinder valve slowly and carefully. If user experiences any difficulty operating
cylinder valve, discontinue use and contact supplier. Never insert an object (e.g.,
wrench, screwdriver, etc.) into valve cap openings. Doing so may damage valve causing a leak to
occur. Use an adjustable strap-wrench to remove over-tight or rusted caps.
This product is compatible with all common materials of construction. Pressure requirements
should be considered when selecting materials and designing systems.
SPECIAL PRECAUTIONS: Always store and handle compressed gas cylinders in accordance
with Compressed Gas Association, Inc. (telephone 703-412-0900) pamphlet CGA P-1, Safe
Handling of Compressed Gases in Containers. Local regulations may require specific equipment
for storage or use.
SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS:
VENTILATION: Not required
RESPIRATORY PROTECTION:
Emergency Use: Not required
EYE PROTECTION: Safety glasses are recommended.
SKIN PROTECTION: Leather work gloves recommended when handling cylinders.
OTHER PROTECTIVE EQUIPMENT: Safety shoes recommended when handling cylinders.

ADDITIONAL NOTES: Air is nontoxic and is necessary to support life. Inhalation of air in high
pressure environments can result in symptoms similar to overexposure to oxygen. These include
tingling of fingers, impaired coordination, and confusion. Decompression sickness (Bends) is
possible following rapid decompression. Decompression equipment may be required if exposed
to high pressure environment.

cylinder valve is properly closed, valve outlet cap has been reinstalled, and valve protection cap
is secured before shipping cylinder.
CAUTION: Compressed gas cylinders shall not be refilled except by qualified producers of
compressed gases. Shipment of a compressed gas cylinder which has not been filled by the
owner or with the owner s written consent is a violation of federal law (49 CFR 173.301).
