Hazards

Routes of Entry: Inhalation:NO Skin:YES Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:FIRST DEGREE BURNS(REDDENING ONLY,AS
SUNBURN)OR SECOND DEGREE BURNS(BLISTERING) WHICH ARE THE RESULT OF
FIRE EXPOSURE & ARE LOCALIZED TO A PORTION OF AN EXTREM ITY OR
SMALL AREA OF BODY MAYBE IMMERSED IN COOL WTR FOR 10-20MINS.
RELIEVE PAINDO NOT IMMERSE THE WHOLE BODY IN A COLD BATH.COVER BURN
AREA W/CLEANEST MATERIAL
Explanation of Carcinogenicity:HYDROGEN IS SIMPLE ASPHYXIANT & HAS NO
TLV.
Effects of Overexposure:CONTACT OF SKIN WITH LIQUID HYDROGEN OR COLD
GAS VAPORS CAN CAUSE CRYOGENIC (EXTREME LOW TEMP) BURNS &
FREEZE TISSUES. SYMPTOMS OF ANOXIA OCCUR ONLY WHEN GAS
CONCENTRATIONS ARE WITHING THE FLAMM ABLE RANGE & THE MIXTURE HAS
NOT IGNITEDDONOT ENTER AREAS WITHIN FLAMMABLE RANGE DUE TO
IMMEDIATE FIRE/EXPLOSION HAZARD.

First Aid

First Aid:CONTACT OF SKIN & EYES FROZEN TISSUES SHOULD BE FLOODED OR
SOAKED W/TEPID WATER (105-115F/41-46C). DO NOT USE HOT WATER!! DO
NOT USE BURN OINTMENTS OR GREASY MATERIALS ON BURNS WHICH SHOW
MORE THAN LOCALIZED REDDENING. PERSONS SUFFERINGFROM LACK OF
OXYGEN SHOULD BE MOVED TO AREAS W/NORMAL ATMOSPHERE. ASSISTED
RESPIRATION & SUPPLEMENTAL OXYGEN SHOULD BE GIVEN IF THE VICTIM IS
NOT BREATHING.

Fire Fighting

Flash Point:NA
Autoignition Temp:Autoignition Temp Text:***
Lower Limits:74.2
Upper Limits:4.0
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:HYDROGEN CAN BURN W/ALMOST INVISIBLE
FLAME. EASILY IGNITED; POTENTIAL EXPLOSION HAZARD FROM REIGNITION
IF FIRE IS EXTINGUISHED W/O SHUTTING OFF HYDROGEN SOURCE.

Accidental Release

Spill Release Procedures:DONOT ENTER AREAS CONTAINING FLAMMABLE
MIXTURES OFHYDROGEN IN AIR. ELIMINATE ALL SOURCES OF IGNITIONMOVE A
LEAKING COMPRESSED GAS CYLINDER OUT OF DOORIF LEAK IS
SMALL.VENTILATE ENCLSD AREAS TO PREVENT FORMATION OF FLAMMABLE OR
OXYGEN DEFICIENT ATMOSPH

Handling

Handling and Storage Precautions:SECURE CYLINDERS WHEN IN USE.STORE IN
WELL VENTILATED AREAS.KEEP CYLINDERS AWAY FROM SOURCES OF
HEATSEGREGATE FULL/EMPTY CYLINDERS.
Other Precautions:AVOID EXPOSURE TO AREAS WHERE SALT OR CORROSIVE
CHEMICALS ARE PRESENT. AVOID HEAVY TRAFFIC AREAS TO PREVENT
DAMAGE.AVOID DRAGGING,ROLLING,& SLIDING CYLINDERSON FLOOR.SEGREGATE
FROM OXIDIZERS SUCH A S OXYGEN,FLUORINE,ETC.

Exposure Controls

Respiratory Protection:OXYGEN DEFICIENT ATMOSPHERS ARE IN THE FLAMMABLE
RANGE. DO NOT ENTER!!!
Ventilation:NATURAL OR MECHANICAL WHERE GAS OR VAPOR IS PRESENT
Protective Gloves:LOOSE FITTING IMPERMEABLE MATL.(LEATHER)
Eye Protection:SAFETY GLASSES/GOGGLES
Other Protective Equipment:NONE
