Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NOOSHA:NO
Health Hazards Acute and Chronic:HELIUM IS NONTOXIC BUT THE LIBERATION
    OF A LARGE AMOUNT IN A CONFINED AREA COULD DISPLACE THE AMOUNT OF
    OXYGEN IN AIR NECESSARY TO SUPPORT LIFE.
Explanation of Carcinogenicity:NONE
Effects of Overexposure:HEADACHE, DIZZINESS, LABORED BREATHING, AND
    EVENTUAL UNCONSCIOUSNESS. BREATHING MIXTURES OF HELIUM WITH
    ADEQUATE OXYGEN TO SUPPORT LIFE MODIFIES THE VOICE SOUND SO THAT IT
    IS HIGHER "PITCHED".

First Aid:INHALATION: MOVE TO FRESH AIR. IF NOT BREATHING GIVE CPR. IF
    BREATHING DIFFICULT GIVE OXYGEN. GET MEDICAL ATTENTION. PROMPT
    MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO
    HELIUM. RESCU E PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED
    BREATHING APPARATUS.
