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

LD50 LC50 Mixture:ORAL (RAT): >230 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 RE DUCES OXYGEN AVAILABLE FOR
    BREATHING & IS HEAVIER THAN AIR. LIQUID CONTACT CAN CAUSE
    FROSTBITE.
Explanation of Carcinogenicity:NONE OF THE COMPONENTS 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 THE VAPORS BY INHALATION MAY
    INCLUDE TEMPORARY NERVOUS SYSTEM DERPESSION WITH ANESTHETIC EFFECTS
    SUCH AS DIZZINESS, HEADACHE, CONFUSION, INCOORDINATION, & LOSS OF
    CONSCIOUSNESS. HIGHER  EXPOSURES TO THE VAPORS MAY CAUSE TEMPORARY
    ALTERATION OF THE HEART'S ELECTRICAL ACTIVITY WITH IRREGULAR PULSE,
    PALPITATIONS, OR INADEQUATE. LIQUID CONTACT CAN CAUSE FROSTBITE.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH PRE-EXISTING
    DISEASES OF THE CENTRAL NERVOUS OR CARDIOVASCULAR SYSTEM MAY HAVE
    INCREASED SUSCEPTIBILITY TO THE TOXICITY OF INCREASED EXPOSURES.

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

First Aid:INHALATION: IF INHALED, IMMEDIATELY REMOVE TO FRESH AIR. KEEP
    PERSON CALM, IF NOT BREATHING, GIVE ARTIFICIAL RESPIRATION. IF
    BREATHING IS DIFFICULT, GIVE OXYGEN. CALL A PHYSICIAN.  SKIN: FLUSH
    WITH LU KEWARM WATER. DO NOT USE HOT WATER. IF FROSTBITE HAS
    OCCURRED, CALL A PHYSICIAN. EYES: IMMEDIATELY FLUSH W/PLENTY OF
    WATER FOR 15 MINUTES. CALL A PHYSICIAN. INGESTION: NOT A PROBABLE
    ROUTE. HOWEVER, I N CASE OF ACCIDENTAL INGESTION, CALL A PHYSICIAN.

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

Flash Point Method:TOC
Flash Point:WILL NOT BURN
Extinguishing Media:AS APPROPRIATE FOR COMBUSTIBLES IN AREA.
Fire Fighting Procedures:KEEP CYLINDERS COOL WITH WATER SPRAY OR FOG.
    SCBA APPARATUS IS REQUIRED IF CYLINDERS RUPTURE AND CONTENTS ARE 
    RELEASED UNDER FIRE CONDITIONS. WATER RUNOFF SHOULD BE CONTAINED
    AND NEUTRALIZED PRIOR TO  RELEASE.
Unusual Fire/Explosion Hazard:CYLINDERS MAY RUPTURE UNDER FIRE
    CONDITIONS. DECOMPOSITION MAY OCCUR. CONTACT OF WELDING OR
    SOLDERING TORCH FLAME WITH HIGH CONCENTRATION OF REFRIGERANT CAN
    RESULT IN VISIBLE CHANGES IN THE SIZE & COL OR OF TORCH FLAMES.
    THIS FLAME EFFECT WILL ONLY OCCUR IN CONCENTRATIONS OF PRODUCT WELL
    ABOVE THE RECOMMENDED EXPOSURE

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

Spill Release Procedures:REMOVE OPEN FLAMES. USE SELF- CONTAINED
    BREATHING APPARATUS (SCBA) FOR LARGE SPILLS OR RELEASES.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

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

Handling and Storage Precautions:STORE IN A CLEAN, DRY PLACE. DO NOT
    HEAT ABOVE 52C (126F).
Other Precautions:AVOID BREATHING VAPORS OR MIST. AVOID LIQUID CONTACT
    WITH EYES OR SKIN. USE WITH SUFFCIENT VENTILATION TO KEEP EMPLOYEE
    EXPOSURE BELOW THE RECOMMENDED LIMITS. AVOID PROLONGED OR REPEATED
    EXPOSURE. WAS H THOROUGHLY AFTER HANDLING.

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

Respiratory Protection:UNDER NORMAL MANUFACTURING CONDITIONS, NO
    RESPIRATORY PROTECTION IS REQUIRED WHEN USING THIS PRODUCT.
    SELF-CONTAINED BREATHING APPARATUS IS REQUIRED IF LARGE RELEASE
    OCCURS.
Ventilation:LOCAL EXHAUST IF LARGE AMOUNTS ARE RELEASED. MECHANICAL
    VENTILATION SHOULD BE USED IN LOW/ENCLOSED PLACES.
Protective Gloves:IMPERVIOUS GLOVES SHOULD BE USED TO AVOID PROLONGED
    OR REPEATED CONTACT.
Eye Protection:CHEMICAL SPLASH GOGGLES.
Other Protective Equipment:NONE SPECIFIED BY MANUFACTURER.
Work Hygienic Practices:WASH CONTAMINATED CLOTHING BEFORE REUSE.
Supplemental Safety and Health
NOTE TO PHYSICIAN: THIS MATERIAL MAY MAKE THE HEART MORE SUSCEPTIBLE TO
    ARRHYTHMIAS. CATECHOLAMINES SUCH AS ADRENALINE, AND OTHER COMPOUNDS
