Health Hazards Acute and Chronic:TARGET ORGANS AFFECTED BY EXPOSURE TO
    THIS MATERIAL ARE: EYES, SKIN, CENTRAL NERVOUS SYSTEM, RESPIRATORY
    SYSTEM, HEART. EYE: IRRITANT. VAPOR IS IRRITATING TO EYES. LIQUID
    IS IRRITATING TO EYES & MAY C AUSE TISSUES TO FREEZE. SKIN:
    IRRITANT. CONTACT WITH LIQUID MAY CAUSE TISSUES TO FREEZE (FROST
    BITE). CHEMICAL ITSELF IS NOT IRRITATING.
Explanation of Carcinogenicity:THIS PRODUCT DOES NOT CONTAIN ANY
    COMPONENTS LISTED BY NTP OR IARC OR REGULATED BY OSHA ASA
    CARCINOGENS.
Effects of Overexposure:IRRITATION, REDNESS AND PAIN FROM FROSTBITES.
Medical Cond Aggravated by Exposure:PERSONS WITH PREEXISTING HEART
    DISEASE MAY BE AT INCREASED RISK FROM EXPOSURE.

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

First Aid:INGESTION: N/A-PRODUCT IS A GAS AT AMBIENT CONDITIONS.
    DERMAL: FLUSH EXPOSED SKIN WITH LUKEWARM WATER (NOT HOT) - OR USE
    OTHER MEANS TO WARM SKIN SLOWLY. GET MEDICAL ATTENTION IF
    FROSTBITTEN BY LIQUID  OR IF IRRITATION OCCURS. EYE: IF IN EYES,
    IMMEDIATELY FLUSH WITH PLENTY OF WATER. GET MEDICAL ATTENTION IF
    IRRITATION PERSISTS. INHALATION: IF INHALED, REMOVE TO FRESH AIR.
    IF NOT BREATHING, GIVE ART IFICIAL RESPIRATION. IF BREATHING IS
    DIFFICULT GIVE OXYGEN. GET MEDICAL ATTENTION.

Autoignition Temp:=632.C, 1169.6F
Lower Limits:NA
Upper Limits:NA
Extinguishing Media:USE EXTINGUISHING  MEDIA APPROPRIATE FOR
    SURROUNDING FIRE CONDITIONS.
Fire Fighting Procedures:FIREFIGHTERS & OTHERS WHO MAY BE EXPOSED TO
    PRODUCTS OF COMBUSTION SHOULD WEAR FULL FIRE FIGHTING TURN OUT GEAR
    (FULL BUNKER GEAR) & SELF CONTAINED BREATHING APPARATUS (PRESSURE
    DEMAND MSAH/NIOSH APPR OVED OR EQUIVALENT). FIRE FIGHTING EQUIPMENT
    SHOULD BE THOROUGHLY DECONTAMINATED AFTER USE.
Unusual Fire/Explosion Hazard:MAY DECOMPOSE DURING CONTACT WITH FLAMES,
    HEATING ELEMENTS, OR IN COMBUSTION ENGINES RELEASING IRRITATING,
    TOXIC, & CORROSIVE GASES. CONTAINER MAY EXPLODE IF HEATED DUE TO
    RESULTING PRESSURE RISE. SOM E MIXTURES OF HCFCS &/OR HFCS, & AIR
    OR OXYGEN MAY BE COMBUSTIBLE IF PRESSURIZED & EXPOSED TO EXTREME
    HEAT OR FLAME

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

Spill Release Procedures:REMOVE OR EXTINGUISH IGNITION OR COMBUSTION
    SOURCES. EVACUATE ENCLOSED SPACES UNTIL GAS IS DISPERSED. KEEP
    UPWIND. STOP LEAK IF POSSIBLE WITHOUT RISK. DISPERSE GAS WITH
    FLOOR-LEVEL FORCED-AIR VENTILAT ION. EXHAUST VAPORS OUTDOORS.
    REMOVE ALL FLAMES, HEATING ELEMENTS & GAS ENGINES. WASH
    CONTAMINATED CLOTHES BEFORE USE. DESTROY CONTAMINATED SHOES.
