=====================  Hazards Identification  =====================

Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:INHALATION OF HIGH CONCENTRATIONS IS
    HARMFUL & MAY CAUSE HEART IRREGULARITIES, UNCONSCIOUSNESS, DEATH.
    INTENTIONAL MISUSE MAY CAUSE DEATH W/O WARNING. VAPORS REDUCE
    OXYGEN CONTENT OF THE AIR (ASPHYXIA TION). LIQUID CONTENT MAY CAUSE
    FROSTBITE.
Explanation of Carcinogenicity:NONE OF THE INGREGREDIENTS PRESENT AT
    0.1% OR GREATER ARE LISTED BY IARC, NTP, OSHA OR ACGIH AS
    CARCINOGENS.
Effects of Overexposure:LIQUID CONTACT:FROSTBITE. INHALATION:HIGH
    CONCENTRATIONS; COUGH, DIFFICULTY BREATHING, SHORTNESS OF BREATH,
    IRREGULAR PULSE, PALPITATIONS, INADEQUATE CIRCULATION, ABNORMAL
    KIDNEY FUNCTION.
Medical Cond Aggravated by Exposure:INDIVIDUALS W/PRE-EXISTING DISEASES
    OF CNS, CARDIOVASCULAR SYTEM, LUNGS OR KIDNEYS MAY HAVE INCREASED
    SUSCEPTIBILITY TO TOXICITY OF EXCESSIVE EXPOSURES.

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

First Aid:IF IRRITATION PERSISTS OR IS SEVERE, GET MEDICAL ATTENTION.
    EYE:FLUSH W/WATER FOR 15 MIN. SKIN:FLUSH AFFECTED AREA W/WATER.
    TREAT FOR FROSTBITE BY GENTLY WARMING AFFECTED AREA. INHALED:
    REMOVE FROM EX POSURE. KEEP VICTIM CALM. AID OR RESTORE BREATHING
    AS NEEDED. INGESTED:NOT CONSIDERED A POTENTIAL ROUTE OF EXPOSURE.

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