Medical Cond Aggravated by Exposure:N/K

First Aid:EYES/SKIN:IF CRYOGENIC LIQUID OR COLD BOIL-OFF GAS CONTACTS A
WORKER'S SKIN OR EYES,FROZEN TISSUES SHOULD BE FLOODED OR SOAKED IN
TEPID WATER (105-115F,41-46C) FOR AT LEAST 15 MIN.DO NOT USE HOT
WATER .BURNS WHICH RESULT IN BLISTERING OR DEEPER TISSUE FREEZING
SHOULD BE SEEN PROMPLY BY A PHYSICIAN.INGESTION:N/A
.INHALATION:REMOVE TO FRESH AIR .

Fire Fighting Procedures:USE NIOSH/MSHA APPROVED SCBA AND FULL
PROTECTIVE EQUIPMENT .OXYGEN IS NONFLAMMABLE,BUT SUPPORTS AND
VIGOROUSLY ACCELERATES COMBUSTION OF FLAMMABLES.
Unusual Fire/Explosion Hazard:SOME MATERIALS WHICH ARE NONCOMBUSTIBLE
IN AIR WILL BURN IN THE PRESENCE OF OXYGEN.

Spill Release Procedures:PREVENT LIQ O*2 FROM CONTACTING
GREASE,OIL,ASPHALT OR COMBUSTIBLES.VENT AREA.FLUSH W/ LRG AMTS OF
WATER.DO NOT ENTER AREAS OF HIGH O*2 CONC,WHICH CAN SATURATE
CLOTHING,INCREASING IT'S FLAMMABILITY.
