Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:EYE/SKIN:NONE KNOWN. INGEST:NONE
    KNOWN. INGEST IS UNLIKELY AS PROD IS GAS AT ROOM TEMP. INHAL:PROD
    IS NON-TOX SIMPLE ASPHY. HIGH CONCS MAY EXCLUDE ADEQ SUPPLY OF OXYG
    TO LUNGS. EFTS OF OXYG DEFICIENCY  RSLTG FROM SIMPLE ASPHYS MAY
    INCL:RAPID BRTHG, DIMINISHED MENTAL ALERTNESS, IMPAIRED MUSCULAR
    COORD, (EFTS OF OVEREXP)
Explanation of Carcinogenicity:NOT RELEVANT
Effects of Overexposure:HLTH HAZ:FAULTY JUDGEMENT, DEPRESS OF ALL
    SENSATIONS, EMOTIONAL INSTABILITY & FATG. AS ASPHY PROGRESSES,
    NAUS, VOMIT, PROSTRATION & LOSS OF CONSCIOUSNESS MAY RSLT,
    EVENTUALLY LEADING TO CONVLS, COMA &  DEATH. OXYG DEFICIENCY DURING
    PREGNANCY HAS PRDCD DEVEL ABNORMS IN HUMANS & EXPTL ANIMALS.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.

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

First Aid:PROMPT MED ATTN IS MANDATORY IN ALL CASES OF OVEREXP. RESCUE
    PERS SHOULD BE EQUIPPED W/NIOSH/MSHA APPRVD SCBA. INGEST:CALL MD

    EQUIP SHOULD BE NON SPARKING & EXPLO PROOF.
Other Precautions:SIMPLE ASPHY-THIS PROD DOES NOT CNTN OXYG & MAY CAUSE
    ASPHYXIA IF RELS IN CONFINED AREA. MAINTAIN OXYG LEVELS >19.5%.
    FLAMM. THIS GAS MIXT IS NONCORR. HOWEVER, HYDROGEN CAN INTERACT
    W/SOME METALS (HAR DENED STEELS) TO CAUSE EMBRITTLEMENT. USE ONLY
    IN WELL-VENTED AREAS. VALVE PROT CAPS MUST REMAIN IN  PLACE  (SUP
    DAT)
