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

Health Hazards Acute and Chronic:INHALATION OF HIGH CONCENTRATIONS OF
    VAPOR IS HARMFUL AND MAY CAUES HEART IRREGULARITIES,
    UNCONSCIOUSNESS, OR DEATH. INTENTIONAL MISUSE OR DELIBERATE
    INHALATION CAN CAUSE DEATH WITHOUT WARNING. VAPOR  REDUCES OXYGEN
    AVAILABLE FOR BREATHING AND IS HEAVIER THAN AIR. LIQUID CONTACT CAN
    CAUSE FROSTBIGHT.
Explanation of Carcinogenicity:NONE OF THE COMPONENETS PRESENT IN THIS
    MATERIAL AT CONCENTRATIONS EQUAL TO OR GREATER THAN 0.1% ARE LISTED
    BY IARC, NTP, OSHA OR ACGIH AS A CARCINOGEN.
Effects of Overexposure:OVEREXPOSURE TO VAPORS BY INHALATION MAY ICLUDE
    TEMPORARY NERVOUS SYSTEM DEPRESSION WITH ANAESTHETIC EFFECTS SUCH
    AS DIZZINESS, HEADACHE, CONFUSION, INCOORDINATION, AND LOSS OF
    CONSCIOUSNESS. HIGHER I NHALATION EXPOSURES TO THE VAPORS MAY CAUSE
    TEMPORARY ALTERATION OF THE HEART'S ELECTRICAL ACTIVITY WITH
    IFREGULAR PULSE, PALPITATIONS, OR INADEQUATE CIRCULATION. FATALITY
    FROM GROSS OVEREXPOSURE MAY  OCCUR. SKIN CONTACT WITH THE LIQUID
    MAY CAUSE FROSTBIGHT.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH PREEXISTING
    DISEASES OF THE CENTRAL NERVOIUS SYSTEM, CARDIOVASCULAR SYSTEM,
    LUNGS OR KIDNEYS MAY HAVE INCREASED SUSCEPTIBILITY TO THE TOXICITY
    TO EXCESSIVE EXPOSURES.

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

First Aid:INHALATION: IF LARGE AMOUNTS ARE INHALED, IMMEDIATELY REMOVE
    TO FRESH AIR. KEEP PERSONS CALM. IF NOT BREATHING, GIVE ARTIFICIAL
    RESPIRATION. IF BREATHING IS DIFFICULT, GIVE OXYGEN AND CALL
    PHYSICIAN.	SKIN CONTACT; IN CASE OF SKI CONTACT, FLUSH WITH WATER
    FOR 15 MINUTES. TREAT FOR FROST BIGHT IF NECESSARY.BY GENTLY
    WARMING AFFECTED AREA. EYE CONTACT: I CASE OF EYE CONTACT,
    IMMEDIATELY FLUSH EYES WI TH PLENTY OF WATER FOR 15 INUTES. CALL A
    PHYSICIAN. INGESTION; INGETTION IS NOT CONCIDERED A POTENTIAL ROUE
    OF EXPOSURE.

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

Fire Fighting Procedures:KEEP CONTAINER COOL WITH WATER SPRAY. SCBA IS
    REQUIRED IF CYLINDERS RUPTURE OR RELEASE UNDER FIRE CONDITIONS.
Unusual Fire/Explosion Hazard:CYLINDERS ARE EQUIPPED WITH TEMPERATURE
    AND PRESSURE RELIEF DEVICES BUT STILL MAY RUPTURE UNDER FIRE
    CONDITIONS. DECOMPOSITION MAY OCCUR.

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

Spill Release Procedures:NOTE: REVIEW FIREFIGHTING MEASURES AND
    HANDLING (PERSONELL) SECTIONS BEFORE PRECEEDIG WITH CLEANUP. USE
    APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT DURING CLEANUP.
    ACCIDENTAL RELEASE MEASURES; VENTELATE  AREA-ESPECIALLLY LOW 
    PLACES WHERE HEABVY VAPORS MIGHT COLLECT. REMOVE OPEN FLAMES. USE
    SCBA FOR LARGE SPILLS. COMPLY WITH FEDERAL, STATE, AND LOCAL
    REGULATIONS FOR REPORTING RELEASES.

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

Handling and Storage Precautions:HANDLING (PERSONELL) AVOID BREATHING
    VAPORS. AVOID LIQUID CONTACT WITH SKIN OR EYES. USE WITH SUFFICIENT
    VENTELATION TO KEEP EMPLOYEE EXPOSURE BELOW RECCOMENDED LIMITS.
    STORAGE: CLEAN, DRY AREA. DO NO T HEAT ABOVE 50 DEGREES CELSEUS
    (125F)
Other Precautions:*NOTE TO PHYSICIAN: BECAUSE OF POSSIBLE DISTERBANCE
    OF CARDIAC RHYTHEM, CATEHOLAMINE DRUGS, SUCH AS EPINEPHRINE, SHOULD
    BE USED WITH SPECIAL CAUTION ONLY IN SITUATIONS OF EMERGENCY LIFE
    SUPPORT.

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

Respiratory Protection:NO RESPIRATORY PROTECTION IS REQUIRED WHEN USING
    THIS PRODUCT. SCBA IS REQUIRED IF A SPILL OR RELEASE OCCURS.
Ventilation:USE WITH SUFFICIENT VENTELATION TO KEEP EMPLOYEE EXPOSURE
    BELOW FRCCOMENDED EXPOSURE LIMITS. LOCAL EXHAUST SHOULD BE USED
    WHEN LARGE ABOUNTS ARE RELEASED.
Protective Gloves:IMPRERVIOUS GLOVE
Eye Protection:CHEMICAL SPLASH GOGGLES
Supplemental Safety and Health
