Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:INHALATION: ASPHYXIANT. IT SHOULD BE
    NOTED THAT BEFORE SUFFOCATION COULD OCCUR, THE LOWER FLAMMABILITY
    LIMIT OF HYDROGEN IN AIR WOULD BE EXCEEDED POSS CAUSING BOTH AN
    OXYGEN-DEFICIENT & EXPLO ATM. EXP OS TO MODERATE CONCS MAY CAUSE
    DIZZINESS, HEADACHE, NAUSEA, VOMITING, EXCESS SALIVATION,
    DIMINISHED (EFTS OF OVEREXP)
Explanation of Carcinogenicity:NOT RELEVANT
Effects of Overexposure:HLTH HAZ: MENTAL ALERTNESS & UNCONSCIOUSNESS.
    EXPOSURE TO ATMS CONTAINING 8-10% OR LESS OXYGEN WILL QUICKLY BRING
    ABOUT UNCONSCIOUSNESS WITHOUT WARNING LEAVING INDIVIDUALS UNABLE TO

    . SKIN: FLUSH W/COPIOUS AMOUNTS OF WATER. CALL MD . INHAL: PE RSONS
    SUFFERING FROM LACK OF OXYGEN SHOULD BE REMOVED TO FRESH AIR. IF
    NOT BREATHING, ADMINISTER ARTIFICIAL RESPIRATION. IF BREATHING IS
    DIFFICULT, ADMINISTER OXYGEN. OBTAIN PROMPT MEDICAL ATTENTION.

==================  Accidental Release Measures  ==================

Spill Release Procedures:EVACUATE IMMED AREA. ELIM ANY POSS SOURCES OF
    IGNIT & PROVIDE MAX EXPLOS-PROOF VENT. SHUT OFF SOURCE OF HYDROGEN,
    IF POSS. IF LEAKING FROM CYL OR VALVE, CALL MFR'S EMER NUMBER.
    PRESENCE OF HYDROGEN FL AME CAN BE DETECTED BY APPROACHING (ING2)
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

======================	Handling and Storage  ======================

    CYL STORAGE LOCATIONS SHOULD BE WELL-PROT, WELL-VENT, DRY &
    SEPARATED FROM COMBUST MATLS. CYLS SHOULD (ING 4)
Other Precautions:DO NOT "OPEN" HYDROGEN CYL VALVE BEFORE CONNECTING IT
    SINCE SELF-IGNIT MAY OCCUR. HYDROGEN IS LIGHTEST GAS KNOWN & MAY
    COLLECT IN TOP OF BLDGS W/OUT PROPER VENT. IT MAY LEAK OUT OF SYS
    WHICH IS GAS-TI GHT FOR AIR/OTHER GASES. LEAK (ING 11)

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:GENERAL USE: NONE. EMERGENCY USE: NIOSH/MSHA
    APPROVED AIR SUPPLIED RESPIRATORS ARE REQUIRED IN OXYGEN-DEFICIENT
    ATMOSPHERES. BEFORE ENTERING AREA CHECK FOR FLAMMABLE OR
    OXYGEN-DEFICIENT ATMOSPHERES.
Ventilation:PROVIDE NATURAL OR EXPLOSION-PROOF VENT ADEQUATE TO ENSURE
    HYDROGEN DOES NOT REACH ITS LOWER EXPLOSIVE LIMIT OF 4%.
Protective Gloves:WORK GLOVES.
Eye Protection:ANSI APPRVD CHEM WORKERS GOGGLES .
Other Protective Equipment:SAFETY SHOES ARE RECOMMENDED WHEN HANDLING
    CYLINDERS.
Work Hygienic Practices:NONE SPECIFIED BY MANUFACTURER.
Supplemental Safety and Health
FIRE FIGHT PROC: EXTING FLAMES. IF FLAMES ARE ACCIDENTALLY EXTING,
    EXPLO RE-IGNIT MAY OCCUR. STOP FLOW OF GAS IF W/OUT RISK WHILE
    CONTINUING COOLING WATER SPRAY. EXPLO HAZ: SECTIONS OF ENCLSD
    SPACES.  PRESS IN CNTNR CAN BUILD UP DUE TO HEAT& IT MAY RUPTURE IF
    PRESS RELIEF DEVICES SHOULD FAIL TO FUNCTION.
