HEALTH HAZARD DATA
TIME WEIGHTED AVERAGE EXPOSURE LIMIT
No TWA established (ACGIH 1994-1995). No PEL (8 Hr. TWA) listed by OSHA 1993.
SYMPTOMS OF EXPOSURE
Air is nontoxic and necessary to support life. Inhalation of air in a high pressure environment such as underwater
diving, caissons or hyperbaric chambers can result in symptoms similar to overexposure to pure oxygen. These include
tingling of fingers and toes, abnormal sensations, impaired coordination and confusion. Decompression sickness, pains
or 鈥渂ends鈥? are possible following rapid decompression.
TOXICOLOGICAL PROPERTIES
High pressure effects (greater than two atmospheres of oxygen) are on the central nervou~ system. Improper
decompression results in the accumulation of nitrogen in the blood.
Air is not listed in thP IARC, NTP or by OSHA as a carcinogen or potential carcinogen.
Persons in ill health when such illness would be aggravated by exposure to high
pressure air should not be allowed to work with or handle this product.
RECOMMENDED FIRST AID TREATMENT
Facilities or practices at which air is breathed in a high pressure environment should be prepared to deal with the
illnesses associated with decompression (bends or caisson disease). Decompression equipment may be required.

SPECIAL HANDLING RECOMMENDATIONS
Valve protection caps must remain in place unless container is secured with valve outlet piped to use point. Do not
drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Use a pressure reducing regulator when
connecting cylinder to lower pressure (<3,000 psig) 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 into the cylinder.
For additional handling recommendations, consult the Compressed Gas Association鈥檚 Pamphlets P-1, G-7, and G-7.1.
SPECIAL STORAGE RECOMMENDATIONS
Protect rylinders from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked areas and
emergency exits. Do not allow the temperature where cylinders are stored to exceed 125潞F (52潞C). Cylinders should be
stored upright and firmly secured to prevent falling or being knocked over. Full and empty cylinders should be
segregated. Use a 鈥渇irst in - first out鈥? inventory system to prevent full cylinders being stored for excessive periods of
time.
For additional storage recommendations, consult the Compressed Gas Association鈥檚 Pamphlets P-1, G-7, and O-7.1.
SPECIAL PACKAGING RECOMMENDATIONS
Dry air is noncorrosive and may be used with all materials of construction. Moisture causes metal oxides which are
formed with air to be hydrated so that they increase in volume and lose their protective role (rust formation).
Concentrations of SO2, Cl2, salt, etc. in the moisture enhances the rusting of metals in air.
OTHER RECOMMENDATIONS OR PRECAUTIONS
Compressed gas cylinders should 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 his (written) consent is a violation of Federal
Law (49CFR).
