Hazards

Routes of Entry: Inhalation:YES Skin:YES Ingestion:YES
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:SYMPTOMS OF ANOXIA OCCUR ONLY WHEN GAS
CONCENTRATIONS ARE WITHIN THE FLAMMABLE RANGE AND THE MIXTURE HAS
NOT IGNITED.
Explanation of Carcinogenicity:HYDROGEN IS NON TOXIC AND CLASSIFIED AS
A SIMPLE ASPHXIANT
Effects of Overexposure:CONTACT OF SKIN WITH LIQUID HYDROGEN OR COLD
GAS VAPORS CAN CAUSE CRYOGENIC (EXTREME LOW TEMPERATURE) BURNS
AND FREEZE TISSUES.

First Aid

First Aid:IF CRYOGENIC LIQUID OR COLD BOIL OFF GAS CONTACTS WORKER'S
SKIN OR EYES, FROZEN TISSUES SHOULD BE FLOODED OR SOAKED W/TEPID
WATER. DO NOT USE HOT WATER. DONOT USE BURN OINTMENTS/GREASY
MATRLS O N BURNS W/MORE THAN LOCALIZED REDDENING.PERSONS SUFFERING
FROM LACK OF OXYGEN SHOULD BE MOVED TO AREAS W/NORMAL AIR. IF
VICTIM IS NOT BREATHING GIVE ASSISTED RESPIRATION & SUPPLEMENTAL
OXYGEN.

Fire Fighting

Flash Point:NA
Autoignition Temp:Autoignition Temp Text:*****
Lower Limits:74.2
Upper Limits:1.0
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:POTENTIAL EXPLOSION HAZARD FROM
REIGNITION IF FIRE IS EXTINGUISHED W/O SHUTTING OFF HYDROGEN
SOURCE. HYDROGEN BURNS W/AN INVISIBLE FLAME OF LOW THERMAL RADIATN

Accidental Release

Spill Release Procedures:DONOT ENTER AREAS CONTAINING FLAMMABLE MIXTURE
OF HYDROGEN IN AIR. ELIMINATE ALL POTENIAL SOURCES OFIGNITION. MOVE
A LEAKING COMPRESSED GAS CYLINDER OUT OF DOORS IF LEAK IS SMALL.
CONSULT AIR PRODUCT FOR ADDITIONAL ASSISTANCE.

Handling

Handling and Storage Precautions:USE ONLY IN WELL VENTILATED AREAS.
SECURE CYLINDERWHEN IN USE. KEEP CYLINDER AWAY FROM HEAT.
