=====================  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:INHALATION-UPTAKE OF TRITIUM WATER
    (HTO) IS QUITE EFFICIENT, 99 PERCENT OF THAT INHALED IS TAKEN INTO
    THE BODY. INGESTION-TRITIUM WATER IS ALMOST COMPLETELY ABSORBED
    FROM THE GASTROINTESTINAL TRACT AN D APPEARS IN VENOUS BLOOD.
    SKIN-UPTAKE INTO SKIN IS ABOUT EQUAL TO THAT OF INHALATION.
Effects of Overexposure:CHRONIC- DURING CHRONIC EXPOSURE, THE RADIATION
    DOSE DUE TO TRITIUM INCORPORATED INTO THE CHROMOSOMES IS TRIVIAL IN
    COMPARISON TO THE DOSE DUE TO TRITIUM IN THE CELL NUCLEUS.	ACUTE-
    ACCIDENTAL RELEAS E OF 10 CURIES OF TRITIUM, UNDER CIRCUMSTANCES
    WHICH WOULD PERMIT INHALATION MAY BE CAPABLE OF PRODUCING DELERIUM.

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

First Aid:INHALATION- VENTILATE THE AREA IMMEDIATELY, MOVE LL PERSONNEL
    UPWIND.  SKIN- WASH ALL EXPOSED SURFACES AS SOON AS POSSIBLE. 
    INGESTION- DRINK COPIOUS QUANTITIES OF FLUIDS, ESPECIALLY WATER
    UNCONTAMINA TED WITH TRITIUM.  SEEK MEDICAL ATTENTION IMMEDIATELY. 
    NOTE: AS SOON AS PRACTICAL, COLLECT 20 ML URINE SAMPLES HOURLY, FOR
    LIQUID SCINTILLATION ANALYSIS BY A LICENSED RADIOLOGICAL
    LABORATORY.

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

Flash Point:FLAMMABLE GAS
Autoignition Temp:Autoignition Temp Text:752F
Extinguishing Media:ALTHOUGH CONTAINS FLAMMABLE GAS, IT MUST BE NOTED
    THT THE TOTAL GAS VOLUME IS <0.5 IN3, FIRE DANGER IS MINIMAL.
Fire Fighting Procedures:UNITS SHOULD NEVER BE ALLOWED TO BURN
    UNNECESSARILY BECUASE THE RELEASE OF RADIOACTIVE GAS MAY EXPOSE
    PERSONNEL DOWNWIND.

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

Spill Release Procedures:RADIOACTIVE TRITIUM IS A SUBSTANCE UNDER
    LICENSED CONTROL. ALL LIGHT SOURCE TRITIUM MUST BE ACCOUNTED FOR BY
