=====================  Hazards Identification  =====================

Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:HYDROGEN IS A SIMPLE ASPHYXIANT WHICH
    WILL DISPLACE THE OXYGEN IN AIR NECESSARY FOR LIFE. OXYGEN
    CONCENTRATION LESS THAN 19.5% MUST BE AVOIDED. MIXTURES OF HYDROGEN
    IN AIR ARE LIMITED TO LESS THAN 2 M OLE-% HYDROGEN, AND THEREFORE
    CONTAIN SUFFICIENT OXYGEN TO PREVENT SYMPTOMS OF ASPHYXIA.
Effects of Overexposure:SEE HEALTH HAZARDS ACUTE AND CHRONIC .

=======================  First Aid Measures  =======================

First Aid:INHALATION: REMOVE PERSON TO UNCONTAMINATED AREA. IF
    BREATHING IS LABORED, ADMINISTER PURE OXYGEN. IF BREATHING HAS
    STOPPED, START ARTIFICAL RESPIRATION. GET IMMEDIATE MEDICAL
    ATTENTION FOR SERIOUS EX POSURE.

=====================  Fire Fighting Measures  =====================

    APPARATUS AND FULL PROTECTIVE EQUIPMENT . USE WATER SPRAY TO KEEP
    CYLINDERS COOL WHEN EXPOSED TO FIRE.
Unusual Fire/Explosion Hazard:GAS CYLINDERS MAY RUPTURE VIOLENTLY WHEN
    EXPOSED TO FIRE. CYLINDER VALVE IS EQUIPPED WITH A PRESSURE RELIEF
    DEVICE TO SAFETY VENT THE CYLINDER IF IT IS EXPOSED TO ELEVATED
    PRESSURE IN A FIRE. ALUMINUM  CYLINDERS EXPOSED TO FIRE MUST BE
    REMOVED FROM SERVICE, SAFELY VENTED, AND RETURNED TO THE OWNER FOR

    EXHAUST VENTILATION TO AVOID HAZARDOUS CONDITIONS.
Protective Gloves:IMPERVIOUS GLOVES .
Eye Protection:ANSI APPROVED CHEMICAL SAFETY GLASSES .
Other Protective Equipment:SAFETY SHOES SHOULD BE WORN WHEN HANDLING
    HIGH PRESSURE CYLINDERS.
