Explanation of Carcinogenicity:HYDROGEN IS NONTOXIC AND CLASSIFIED AS A
SIMPLE ASPHYXIANT
Effects of Overexposure:CONTACT TO SKIN WITH LIQUID HYDROGEN OR COLD
GAS VAPORS CAN CAUSE CRYOGENIC (EXTREME LOW TEMPERATURE) BURNS
AND FREEZE TISSUES.

First Aid:IF CRYOGENIC LIQUID OR COLD BOIL OFF GAS CONTACTS A WORKER'S
SKIN OR EYES, FROZEN TISSUES SHOULD BE FLOODED OR SOAKED
W/TEPID WATER. DO NOT USE HOT WATER!!DO NOT USE BURN OINTMENTS OR
GREASY MATE RIALS ON BURNS WHICH SHOW MORE THANLOCALIZED REDDENING.
PERSONS SUFFERING FROM LACK OF OXYGEN SHOULD BE MOVED TO AREAS
W/NORMAL ATMOSPHERE.RESPIRATION/OXYGEN SHOULD BE GIVEN IF NOT
BREATHING.

Extinguishing Media:DRY CHEMICAL, CARBON DIOXIDE, OR HALON
Fire Fighting Procedures:SHUT OFF SOURCE OF HYDROGEN. WHEN POSSIBLE
ALLOW FIRE TO BURN ITSELF OUT. SPRAY WATER ON ADJOINING EQUIPMENT
TO KEEP IT COOL
Unusual Fire/Explosion Hazard:HYDROGEN CAN BURN W/ALMOST AN INVISIBLE
FLAME OF LOW THERMAL RADIATION.POTENTIALEXPLOSION HAZARD FROM
REIGNITION IF FIRE IS EXTINGUISHED W/O SHUTTING OFF SOURCE

Spill Release Procedures:ELIMINATE ALL POTENTIAL SOURCES OF IGNITION.
MOVE LEAKING COMPRESSED GAS CYLINDER OUT OF DOORS IF LEAK IS
SMALL. DO NOT ENTER AREAS CONTAINING FLAMMABLE MIXTURES OF
HYDROGEN IN AIR. CONSULT BROWN INDUSTRIES FOR ADDITIONAL
ASSISTANCE.

Handling and Storage Precautions:USE ONLY IN WELL VENTL AREA.SECURE
CYLINDERS W/USESEGREGATE FULL/EMPTY CYLINDERS. STORAGE AREAS
SHOULD BE FREE OF COMBUSTIBLE MATL.
Other Precautions:NEVER USE DIRECT FLAME TO HEAT A COMPRESSED GAS
CYLINDER. USE ONLY METALS & MATERIALS COMPATIBLE W/EXTREMELY
LOW TEMPERATURES. AVOID EXPOSURE TO AREAS WHERESALT OR CORROSIVE
CHEMICALS ARE PRESENT. AVOID DRAGGING,ROLLING,SLIDING CYLINDER
