Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:LIQUID OXYGEN OR COLD GAS WILL FREEZE
TISSUE AND CAN CAUSE SEVERE CRYOGENIC BURNS.PARTIAL PRESSURE OF
OXYGEN IN EXCESS OF TWO ATMOSPHERES MAY CAUSE CNS EFFECTS.SEVERE
HAZARDS MAY BE PRESENT WHEN CONF AND IMPAIRED JUDGMENT LEAD TO
OPERATIONAL ERRORS.INFANTS EXPOSED TO >35-40% OXYGEN MAY HAVE
VISUAL IMPAIRMENT/BLINDNESS.
Explanation of Carcinogenicity:NONE
Effects of Overexposure:EYES/SKIN/INGESTION/INHALATION:CRYOGENIC
BURNS,TISSUE FREEZING.BREATHING PURE OXYGEN:COUGH,CHEST PAIN IN
8-24 HOURS.BREATHING 60% OXYGEN:COUGH,CHEST PAIN IN DAYS.BREATHING

First Aid:EYES/SKIN:IN CASE OF CONTACT WITH CRYOGENIC LIQUID OR COLD
BOIL-OFF GAS,FLOOD OR SOAK FROZEN TISSUE IN TEPID WATER
(105-115F,41-46C).DO NOT USE HOT WATER.IF BLISTERING OR DEEP TISSUE
FREEZING OCCURS,S EE A PHYSICIAN PROMPTLY.INGESTION/INHALATION:N/K
.

Fire Fighting Procedures:OXYGEN IS NONFLAMMABLE,BUT SUPPORTS AND
VIGOROUSLY ACCELERATES COMBUSTION OF FLAMMABLES.SHUT OFF SOURCES OF
OXYGEN AND FIGHT LIKE CONVENTIONAL FIRES.
Unusual Fire/Explosion Hazard:NONFLAMMABLE,BUT SUPPORTS AND VIGOROUSLY
ACCELERATES COMBUSTION.SOME MATERIALS WHICH ARE NONCOMBUSTIBLE IN
AIR WILL BURN IN THE PRESENCE OF OXYGEN.

Spill Release Procedures:PREVENT LIQUID OXYGEN FROM CONTACTING
GREASE,OIL,ASPHALT OR COMBUSTIBLES.VENTILATE AREA AND FLUSH WITH
LARGE AMOUNTS OF WATER.DO NOT ENTER AREA.EXPOSURE CAN INCREASE THE
FLAMMABILITY OF CLOTHING.DO NO T SMOKE OR CONTACT IGNITION SOURCE
AFTER EXPOSURE.
