*  Exposure Controls/Personal Protection  *
Respiratory Protection:USE SELF-CONTAINED BREATHING APPARATUS IN
    OXYGEN-DEFICIENT ATMOSPHERES. CAUTION-AIR PURIFYING RESPIRATORS
    WILL NOT FUNCTION. THEIR USE MAY RESULT IN ASPHYXIATION.
Ventilation:NATURAL OR MECHANICAL WHERE GAS IS PRESENT.
Other Protective Equipment:NONE
Supplemental Safety and Health
EYE-SAFETY GLASSES ARE RECOMMENDED WHEN HANDLING HIGH-PRESSURE
    GLASSES WHEN HANDLING LIQUID. VENTILATION-VENTS SHOULD BE SITUATED
    TO AVOID  HIGHER THAN NATURAL CONCENTRATION OF HELIUM IN WORK
    AREAS.
*  Product Identification  *
Product ID:HELIUM
*  Composition/Information on Ingredients  *
*  Hazards Identification  *
Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Reports of Carcinogenicity:NTP:NO    IARC:NOOSHA:NO
Health Hazards Acute and Chronic:HELIUM IS ODORLESS AND NONTOXIC BUT
    MAY PRODUCE SUFFOCATION BY DILUTING THE CONCENTRATION OF OXYGEN IN
    AIR BELOW LEVELS NECESSARY TO SUPPORT LIFE. EXTENSIVE TISSUE DAMAGE
    OR BURNS CAN RESULT FROM EXPO SURE TO LIQUID HELIUM OR COLD HELIUM
    VAPORS.
Explanation of Carcinogenicity:HELIUM IS A SIMPLE ASPHYXIANT AND HAS NO
    TRESHOLD LIMIT VALUE (TLV). HELIUM NOT LISTED AS CARCINOGEN BY
    NTP/IARC/OSHA.
Effects of Overexposure:DIZZINESS/NAUSEA/VOMITING/LOSS OF
    CONSCIOUSNESS. DEATH MAY RESULT FROM ERRORS IN JUDGEMENT,
    CONFUSION, OR LOSS OF CONSCIOUSNESS WHICH PREVENTS SELF-RESCUE. AT
    LOW OXYGEN CONCENTRATIONS UNCONSCIOUSNESS  AND DEATH MAY OCCUR IN
    SECONDS WITHOUTWARNING.
*  First Aid Measures  *
First Aid:ASSISTED RESPIRATION AND SUPPLEMNETAL OXYGEN SHOULD BE GIVEN
    IF THE VICTIM IS NOT BREATHING. IF CRYOGENIC LIQUID OR COLD
    BOIL-OFF GAS CONTACTS A WORKERS SKIN OR EYES, FROZEN TISSUES SHOULD
    USE HOT WATER. CRYOGENIC BURNS WHICH RESULTS IN BLISTERING OR
    DEEPER TISSUE FREEZING SHOULD BE SEEN PROMPTLY BY A PHYSICIAN.
*  Fire Fighting Measures  *
Flash Point:NONE LISTED
Lower Limits:NONE LISTED
Upper Limits:NONE LISTED
*  Accidental Release Measures  *
Spill Release Procedures:AVOID CONTACT OF SKIN WITH LIQUID HELIUM OR
    ITS COLD BOIL-OFF GAS. FLUSH LIQUID SPILL WITH WATER TO DISPERSE.
    VENTILATE ENCLOSED AREAS TO PREVENT FORMATION OF OXYGEN-DEFICIENT
    ATMOSPHERES CAUSED BY EV APORAT OR LIQ HELIUM OR RELEASE OF GASEOUS
    HELIUM.
*Handling and Storage  *
Handling and Storage Precautions:PREVENT ENTRAPMENT OF LIQUID IN CLOSED
    SYSTEMS. USE IN WELL VENTED AREAS. AVOID EXPOSURE TO AREAS WHERE
    SALT OR CORROSIVE CHEMICALS ARE PRESENT.
Other Precautions:LIQUID HELIUM IN EXPOSED PIPING CAN CAUSE AIR TO
    CONDENSE AND LIQUIFY. UTILIZE OXYGEN-COMPATIBLE INSULATING
    MATERIALS AND MINIMIZE EXPOSED PIPING AREAS. AVOID USE OF CARBON
    STEEL AND OTHER METAL WHICH  BECOME BRITTLE AT LOW TEMPERATURES.
*  Physical/Chemical Properties  *
Appearance and Odor:HELIUM IS COLORLESS AND ODORLESS IN BOTH GASEOUS
    AND LIQUID STATES.
*  Stability and Reactivity Data  *
Stability Indicator/Materials to Avoid:YES
NONE
Stability Condition to Avoid:NONE
Hazardous Decomposition Products:NONE
*  Disposal Considerations  *
Waste Disposal Methods:ALLOW LIQUID HELIUM TO EVAP IN A WELL-VENT
    LOCATION REMOTE FROM WORK AREAS. VENT HELIUM GAS SLOWLY TO A
    WELL-VENT OUTDOOR LOCATION REMOTE FROM WORK AREA. DO NOT ATTEMPT TO
    DISPOSE OF RESIDUAL HELIUM I N COMPRESSED GAS CYLINDERS.
