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

Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:PERSONNEL, INCLUDING RESCUE WORKERS,
    SHOULD NOT ENTER AREAS WHERE THE OXYGEN    CONCENTRATION IS BELOW
    19%, UNLESS PROVIDED W/SELFCONTAINED BREATHING APPARATUS OR AIRLINE
    RESPIRATOR.
Explanation of Carcinogenicity:HELIUM IS A SIMPLE ASPHYXIANT AND HAS NO
    TLV
Effects of Overexposure:EXPOSURE TO OXYGEN DEFICIENT ATMOSPHERES MAY
    PRODUCE DIZZINESS,NAUSEA,VOMITING, LOSS OF CONSCIOUSNESS, AND
    DEATH. EXTENSIVE TISSUE DAMAGE OR BURNS CAN RESULT	 FROM EXPOSURE
    TO LIQUID HELIUM OR COLD H ELIUM VAPORS.

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

First Aid:PERSONS SUFFERING FROM LACK OF OXYGEN SHOULD BE MOVED TO
    AREAS WITH NORMAL ATMOSPHERES. ASSISTED RESPIRATION & SUPPLEMENTAL
    OXYGEN SHOULD BE GIVEN IF VICTIM IS NOT BREATHING. IF CRYOGENIC
    LIQUID OR CO LD BOIL OFF GAS CONTACTS WORKER'S SKINOR EYES, FROZEN
    TISSUES SHOULD BE FLOODED/SOAKED W/TEPID WATER(105-115F;41-46C) DO
    NOT USE HOT WATER!! SHOULD SEEK MEDICAL ATTENTION IMMEDIATELY.

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

Spill Release Procedures:AVOID CONTACT OF SKIN W/LIQUID HELIUM OR ITS
    COLD BOIL OFF GAS. FLUSH LIQ SPILL W/WTR TO DISPERSE.  VENTILATE
    ENCLOSED AREAS TO PREVENT FORMATION OF  OXYGEN DEFICIENT
    ATMOSPHERES CAUSED BY EVAPORATION OF LIQUID HELIUM OR THE RELEASE
    OF GASEOUS HELIUM.

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

Handling and Storage Precautions:PREVENT CONTACT OF LIQ HELIUM/COLD
    BOILOFF GAS W/ SKIN.USE A SUITABLE HANDTRUCK.STORE LIQ CONTNR & 
    CYLINDER IN WELL VENTL AREA.KEEP FROM SOURCES HEAT
Other Precautions:STORAGE SHOULD NOT BE A HEAVY TRAFFICKED AREA.
    SEGREGATE FULL & EMPTY CYLINDERS.AVOID EXPOSURE TO AREAS WHERE SALT
    OR CORROSIVE CHEMICAL ARE PRESENT. STORAGE	 SHOULD BE FREE OF
    COMBUSTIBLE MATERIAL.A VOID ROLLING,DRAGGING,OR SLIDING CYLNDR.

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

Respiratory Protection:SELFCONTAINED BREATHING APPARATUS IN OXYGEN
    DEFICIENT ATMOSPHERES. CAUTION!!	RESPIRATORS WILL NOT FUNCTION.
    USE MAY RESULT IN ASPHYXIATION.
Ventilation:NATURAL OR MECHANICAL WHERE GAS IS PRESENT. VENTS SHOULD BE
    SITUATED TO AVOID HIGHER THAN NORML CONCENTRATION OF HELIUM
Protective Gloves:LOOSE FITTING OF IMPERMEABLE AS LEATHER

====================  Disposal Considerations  ====================

Waste Disposal Methods:ALLOW LIQUID HELIUM TO EVAPORATE IN A WELL      
     VENTILATED LOCATION REMOTE FROM WORK AREAS. DO NOTATTEMPT TO
    DISPOSE RESIDUAL HELIUM IN COMPRESSED  GAS CYLINDERS. VENT HELIUM
    GAS SLOWLY TO A WELL    VENTL OUTDOORS LOCATION REMOTE FROM WORK
    AREAS.
