Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:ACUTE: EXTENDED EXPOSURES TO OXYGEN AT
HIGHER PRESSURES MAY BE HAZARDOUS. A VARIETY OF CENTRAL NEVEROUS
SYSTEM EFFECTS MAY RESULT FROM BREATHING OXYGEN GREATER THAN 2
ATM., SUCH AS DIZZINESS, IMPAIRED COORDINATION, VISUAL AND HEARING
DISTURBANCES, AND SEIZURES. CONTACT WITH LIQUID OXYGEN CAN CAUSE
SEVERE FROSTBITE.
Explanation of Carcinogenicity:NONE
Effects of Overexposure:PROLONGED BREATHING OF VERY COOL ATMOSPHERES
CAN CAUSE LUNG DAMAGE. PROLONGED EXPOSURE TO COLD AREAS CAN RESULT
IN HYPOTHERMIA.
Medical Cond Aggravated by Exposure:NONE

First Aid:REMOVE TO FRESH AIR. IF CONTACT WITH LIQUID, REMOVE VICTIM
FROM SOURCE OF CONTACT. FLUSH AFFECTED AREA WITH LOTS OF TEPID
WATER. DO NOT APPLY DIRECT HEAT. DO NOT RUB FROZEN AREA.

Extinguishing Media:USE WHAT IS APPROPRIATE FOR SURROUNDING FIRE.
Fire Fighting Procedures:SHUT OFF OXYGEN GAS IF POSSIBLE. USE WATER
SPRAY TO KEEP FIRE EXPOSED CYLINDERS COOL. REMOVE CYLINDERS IF
POSSIBLE. WEAR SELF-CONTAINED BREATHING APPARATUS.
Unusual Fire/Explosion Hazard:HIGH OXIDIZING ATMOSPHERES INCREASE
LIKLIHOOD OF FIRES. OXYGEN VIGOUROUSLY SUPPORTS COMBUSTION.

Spill Release Procedures:EVACUATE AND VENTILATE AREA. SHUT OFF OXYGEN
SOURCE. REMOVE SOURCES OF HEAT AND IGNITION, AND IF POSSIBLE,
COMBUSTIBLES.
Neutralizing Agent:NOT APPLICABLE.
