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

LD50 LC50 Mixture:4-HOUR LC-50 (RAT): 220,000 PPM
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 OF
    VAPOR IS HARMFUL & MAY CAUSE HEART IRREGULARITIES, UNCONSCIOUSNESS
    OR DEATH. INTENTIONAL MISUSE OR DELIBERATE INHALATION MAY CAUSE
    DEATH WITHOUT WARNING. VAPOR RED UCES OXYGEN AVAILABLE FOR
    BREATHING & IS HEAVIER THAN AIR. LIQUID CONTACT CAN CAUSE
    FROSTBITE.
Explanation of Carcinogenicity:NO INGREDIENT OF A CONCENTRATION OF 0.1%
    OR GREATER IS LISTED AS A CARCINOGEN OR SUSPECTED CARCINOGEN.
Effects of Overexposure:SKIN-FROSTBITE, DEFATTING, DRYNESS.
    EYES-IRRITATION, DISCOMFORT, TEARING, BLURRING OF VISION.
    INHALED-DIZZINESS, HEADACHE, CONFUSION, INCOORDINATION, LOSS OF
    CONSCIOUSNESS, IRREGULAR HEART BEAT.
Medical Cond Aggravated by Exposure:PRE-EXISTING DISEASES OF THE
    CANTRAL NERVOUS OR CARDIOVASCULAR SYSTEMS MAY HAVE INCREASED
    SUSCEPTIBILITY TO THE TOXICITY OF EXCESSIVE OVEREXPOSURES.

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

First Aid:SKIN-FLUSH WITH LUKEWARM (NOT HOT!) WATER. CALL A PHYSICIAN
    IF FROSTBITE HAS OCCURED. INHALED-IMMEDIATELY REMOVE TO FRESH AIR.
    KEEP PERSON CALM. GIVE ARTIFICIAL RESPIRATION IF NOT BREATHING.
    GIVE OXYG EN IF BREATHING DIFFICULT. CALL A PHYSICIAN.
    EYES-IMMEDIATELY FLUSH WITH WATER FOR 15 MINUTES. CALL A PHYSICIAN.
    INGESTION IS NOT CONSIDERED A POTENTIAL ROUTE OF EXPOSURE.

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

Flash Point:NONE
Autoignition Temp:Autoignition Temp Text:1170F
Extinguishing Media:AS APPROPRIATE FOR COMBUSTIBLES IN AREA.
    EXTINGUISHANT FOR OTHER BURNING MATERIAL IN AREA IS SUFFICIENT TO
    STOP BURNING.
Fire Fighting Procedures:WEAR SELF-CONTAINED BREATHING APPARATUS AND
    FULL FIRE FIGHTER'S PROTECTIVE GEAR. USE WATER TO COOL FIRE EXPOSED
    CONTAINERS.
Unusual Fire/Explosion Hazard:COMPRESSED GAS. CYLINDERS MAY EXPLODE IF
    EXPOSED TO FIRE. DECOMPOSITION MAY OCCUR.

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

Spill Release Procedures:USE APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT.
    VENTILATE AREA, ESPECIALLY LOW OR ENCLOSED AREAS.  REMOVE OPEN
    FLAMES. USE SCBA FOR LARGE SPILLS.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

======================	Handling and Storage  ======================

Handling and Storage Precautions:STORE IN COOL, DRY, WELL VENTILATED
    AREA. DO NOT HEAT ABOVE 125F (52C). USE WITH SUFFICIENT VENTILATION
    TO EXPOSURE BELOW RECOMMENDED LIMITS.
Other Precautions:PRODUCT SHOULD NOT BE USED OR ALLOWED TO BE PRESENT
    WITH HIGH CONENTRATIONS OF AIR ABOOVE ATMOSPHERIC PRESSURE. CONTACT
    W/CHLORINE OR OTHER STRONG OXIDIZING AGENTS SHOULD BE AVOIDED.
    LIQUIFIED GAS UND ER PRESSURE. CLOSE VALVE WHEN NOT IN USE

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:NONE NORMALLY REQUIRED. IF ENGINEERING CONTROLS
    FAIL OR NON-ROUTINE USE OR AN EMERGENCY OCCURS; WEAR AN MSHA/NIOSH
    APPROVED AIR-SUPPLIED RESPIRATOR OR SCBA, AS REQUIRED. USE IAW 29
    CFR 1910.134.
Ventilation:NORMAL VENTILATION IS GENERALLY ADEQUATE. LOCAL EXHAUST
    USED FOR LARGE RELEASES; MECHANICAL FOR LOW OR ENCLOSED AREAS.
Protective Gloves:IMPERVIOUS.
Eye Protection:CHEMICAL SPLASH GOGGLES.
Other Protective Equipment:NONE SPECIFIED BY MANUFACTURER.
Work Hygienic Practices:WASH HANDS BEFORE EATING, DRINKING, OR SMOKING.
