HEALTH HAZARD DATA
TIME WEIGHTED AVERAGE EXPOSURE LIMIT
None established (ACGIH 1994-1995 ). Oxygen is the 鈥渧ital element鈥? in the
atmospherewhich we live and breathe (Continued on Page 4)
SYMPTOMS OF EXPOSURE
Breathing high concentrations of oxygen (greater than 75 molar percent) causes symptom of hyperoxia which includes
cramps, nausea, dizziness, hypothermia, amblyopia, respiratory difficulties, bradycardia, fainting spells, and
convulsions capable of leading to death.
For additional informaton on hyperoxia, see Compressed Gas Association鈥檚 Pamphlet P-14.
TOXICOLOGICAL PROPERTIES
The property is that of hyperoxia which leads to pneumonia. Concentrations of oxygen between 25 and 75 molar
percent present a risk of inflammation of organic matter in the body.
Neither oxygen or nitrogen are listed in the IARC, NTP or by OSHA as a carcinogen or
potential carcinogen.
Persons in ill health where such illness would be aggravated by exposure to this
oxidizing mixture should not be allowed to work with or handle this product.
RECOMMENDED FIRST AID TREATMENT
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO THIS OXIDIZING
MIXTURE. RESCUE PERSONNEL SHOULD BE COGNIZANT Of EXTREME FIRE HAZARD ASSOCIATED WITH
OXYGEN-RICH ATMOSPHERES.
Conscious persons should be assisted to an uncontaminated area and breathe fresh air.They should be kept warm and
quiet. The physician should be informed that the victim is experiencing (has experienced) hyperoxia.
Unconscious persons should be moved to an uncontaminated area and given
assisted respiration. When breathing has been restored, treatment should be as above.
Continued treatment should be symptomatic and supportive.

HAZARDOUS MIXTURES OF OTHER LIQUIDS, SOLIDS, OR GASES
Oxygen vigorously accelerates combustion. Contact will all flammable materials should be avoided. Some materials
which are not flammable in air will burn in pure oxygen or oxygen-enriched atmospheres.

SPECIAL PRECAUTIONS*
SPECIAL LABELING INFORMATION
No DOT labeling is required on pipeline products. OSHA requirements suggest that
pipelines and process equipment should be labeled to reflect (Cont鈥檇 onPage 4)
SPECIAL HANDLING RECOMMENDATIONS
The precautions associated with handling high pressure gases should be observed with 鈥減ipeline鈥? oxygen. Materials to
contain the product must be adequately sized and of proper pressure rating. Arrange residual gas vents to a 鈥渟afe鈥?
outside location. If a leak or malfunction occurs in the pipeline or its appurtenances, contact your closest AGA supplier
location immediately.
SPECIAL STORAGE RECOMMENDATIONS
See Special Handling Recommendations
SPECIAL PACKAGING RECOMMENDATIONS
Carbon steels and low alloy steels are acceptable for use at lower pressures. For high pressure applications use
stainless steels, copper and its alloys, nickel and its alloys, brass, bronze, silicon alloys, Monel庐, Inconel庐 or beryllium.
Lead and silver or lead and tin alloys are good gasketing materials. Teflon庐 and Kel-F庐 are the preferred nonmetal
gaskets.
Special Note: It should be recognized that the ignition temperature of metals and non-metals in oxygen service
decreases with increasing oxygen pressure.
OTHER RECOMMENDATIONS OR PRECAUTIONS
Oxygen should not be used as a substitute for compressed air in pneumatic equipment since this type generally
contains flammable lubricants. Equipment to contain oxygen must be 鈥渃leaned for oxygen service.鈥? See Compressed
Gas Association Pamphlet G-4.1.
