Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NOOSHA:NO
Health Hazards Acute and Chronic:THIS PRODUCT IS A SIMPLE ASPHYXIANT.
    IN HIGHT CONCENTRATION IT WILL DISPLACE OXYGEN FROM THE BREATHING
    ATMOSPHERE, PARTICULARLY IN CONFINED SPACES. SIGNS OF ASPHYXIATION
    IN SEVERAL STAGES.ON EYE OR SKIN CONTACT, NOT IRRITATING.
    HOWEVER, CONTACT WITH PRESSURIZED VAPOR MAY CAUSE FROSTBITE, FREEZE
    BURNS, AND PERMANENT EYE DAMAGE.
Explanation of Carcinogenicity:NONE LISTED.
Effects of Overexposure:A "CHILLY" FEELING, AND VOMITING HAVE BEEN
    REPORTED FROM ACCIDENTAL EXPOSURE TO HIGH CONCENTRATIONS. SYMPTOMS
    OF ASPHYXIATION MAY INCLUDE RAPID BREATHING AND PULSE RATE,
    HEADACHE, DIZZINESS, VISUAL DI STURBANCES, MENTAL CONFUSION,
    INCOORDINATION, MOOD CHANGES, MUSCULAR WEAKNESS, TREMORS, CYANOSIS,
    NARCOSIS AND NUMBNESS OF THE EXTREMITIES.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH PRE-EXISTING
    CONDITIONS OF THE HEART, LUNGS, AND BLOOD MAY HAVE INCREASED
    SUSCEPTIBILITY TO SYMPTOMS OF ASPHYXIA.
*  First Aid Measures  *
First Aid:EYE: IN CASE OF FREEZE BURN COVER EYES TO PROTECT FROM LIGHT.
    SEEK MEDICAL HELP. SKIN: IN CASE OF FROSTBITE OR FREEZE BURNS SEEK
    MEDICAL HELP. INGEST: UNLIKELY. INHALE: REMOVE PERSON TO FRESH AIR.
    IFPERSON IS NOT BREATHING, PROVIDE ARTIFICIAL RESPIRATION. IF
    NECESSARY, PROVIDE ADDITIONAL OXYGEN ONCE BREATHING IS RESTORED IF
    TRAINED TO DO SO. SEEK MEDICAL HELP.
*  Fire Fighting Measures  *
Flash Point:FLAMMABLE GAS
Lower Limits:3.8-6.5%
Extinguishing Media:DRY CHEMICAL, CARBON DIOXIDE, HALON OR WATER.
    HOWEVER, FIRE SHOULD NOT BE EXTINGUISHED UNLESS FLOW OF GAS CAN BE
    IMMERDIATELY STOPPED.
Fire Fighting Procedures:GAS FIRES SHOULD NOT BE EXTINGUISHED UNLESS
    FLOW OF GAS CAN BE IMMEDIATELY STOPPED. SHUT OFF GAS SOURCE AND
    ALLOW GAS TO BURN OUT. IF SPILL OR LEAK HAS NOT IGNITED, DETERMINE
    IF WATER SPRAY MAY ASSIST  IN DISPERSING GS OR VAPOR TO PROTECT
    PERSONNEL ATTEMPTING TO STOP LEAK.
Unusual Fire/Explosion Hazard:NATURAL GS IS LIGHTER THAN AIR AND MAY
    TRAVEL LONG DISTANCES TO A POINT OF IGNITION AND FLASH
    BACK.CONTAINERS MAY EXPLODE IN HEAT OR FIRE.
*  Accidental Release Measures  *
Spill Release Procedures:EVACUATE NONESSENTIAL PERSONNEL AND SECURE ALL
    IGNITION SOURCES. NO ROAD FLARES, SMOKING OR FLAMES IN HAZARD AREA.
    STAY UPWIND IF POSSIBLE. STOP SOURCE OF THE RELEASE IF SAFE TO DO
    SO. CONSIDER THE US E OF WATER SPRAY TO DISPERSE VAPORS. ISOLATE
    THE AREA UNTIL GAS HAS DISPERSED. VENTILATE AND GAS TEST AREA
    BEFORE ENTERING.
*Handling and Storage  *
Handling and Storage Precautions:KEEP AWAY FROM FLAMES, SPARKS AND
    EXCESSIVE TEMPERATURES. STORE ONLY IN APPROVED CONTAINERS. BOND AND
    GROUND CONTAINERS. USE ONLY IN WELL VENTILATED AREAS.
