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

LD50 LC50 Mixture:NONE SPECIFIED BY MANUFACTURER.
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:PER MSDS: CARCINOGENICITY: NONE OF
    COMPONENTS PRESENT IN MATERIAL AT CONCENTRATIONS EQUAL TO/>0.1%
    LISTED BY IARC/NTP/OSHA/ACGIH AS CARCINOGEN.
Effects of Overexposure:OVEREXPOSURE TO VAPORS BY INHALATION MAY
    INCLUDE TEMPORARY NERVOUS SYSTEM DEPRESSION WITH ANESTHETIC EFFECTS
    SUCH AS DIZZINESS, HEADACHE, CONFUSION, INCOORDINATION & LOSS OF
    CONSCIOUSNESS. HIGHER EXPO SURES TO VAPORS MAY CAUSE TEMPORARY
    ALTERATION OF HEART'S ELECTRICAL ACTIVITY WITH IRREGULAR PULSE,
    PALPITATIONS OR INADEQUATE CIRCULATION; FATALITY FROM GROSS
    OVEREXPOSURE. CONTACT WITH LIQUID MAY CA USE FROSTBITE.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH PREEXISTING
    DISEASES OF THE CENTRAL NERVOUS OR CARDIOVASCULAR SYSTEM MAY HAVE
    INCREASED SUSCEPTIBILITY TO THE TOXICITY OF INCREASED EXPOSURES.

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

First Aid:INHALATION: IMMEDIATELY REMOVE TO FRESH AIR. KEEP PERSON
    CALM. IF NOT BREATHING GIVE ARTIFICIAL RESPIRATION. IF BREATHING IS
    DIFFICULT GIVE OXYGEN. CALL PHYSICIAN. SKIN: FLUSH WITH LUKEWARM
    WATER. DO  NOT USE HOT WATER. IF FROSTBITE HAS OCCURRED CALL
    PHSYICIAN. EYE:IMMEDIATELY FLUSH WITH PLENTY OF WATER FOR AT LEAST
    15MINS. CALL PHYSICIAN. INGESTION: NOT PROBABLE ROUTE, HOWEVER IN
    CASE OF ACCIDENTA L INGESTION CALL PHYSICIAN. NOTE TO PHYSICIAN:
    CATECHOLAMINES SUCH AS ADRENALINE & OTHER COMPOUNDS HAVING SIMILAR
    EFFECTS SHOULD BE RESERVED FOR EMERGENCIES & THEN ONLY USED WITH
    SPECIAL CAUTION.

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

Flash Point:WILL NOT BURN
Autoignition Temp:Autoignition Temp Text:UNK
Extinguishing Media:AS APPROPRIATE FOR COMBUSTIBLES IN AREA.
Fire Fighting Procedures:COOL CYLINDER WITH WATER SPRAY OR FOG.
    SELF-CONTAINED BREATHING APPRATUS (SCBA) IS REQUIRED IF CYLINDERS
    RUPTURE & CONTENTS ARE RELEASED UNDER FIRE CONDITIONS. WATER RUNOFF
    SHOULD BE CONTAINED & NEUTR ALIZED PRIOR TO RELEASE.
Unusual Fire/Explosion Hazard:NOT FLAMMABLE UP TO 212F & ATMOSPHERIC
    PRESSURE. BUT MIXTURES IN HIGH CONCENTRATIONS OF AIR AT ELEVATED
    TEMPERATURE CAN BECOME COMBUSTIBLE AT AMBIENT TEMPERATURE. AS
    TEMPERATURE IS INCREASED, LOWER PR ESSURE (STILL > ATMOSPHERIC) CAN
    CREATE SAME EFFECT. THEREFORE PRODUCT SHOULD NOT BE MIXED WITH AIR
    UNDER PRESSURE.

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

Spill Release Procedures:REVIEW FIREFIGHTING MEASURES &
    HANDLING/STORAGE SECTIONS BEFORE CLEANUP. USE APPROPRIATE PPE
    DURING CLEANUP. VENTILATE AREA WITH FORCED VENTILATION, ESPECIALLY
    IN LOW OR ENCLOSED AREAS WHERE VAPORS CA N COLLECT. 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:AVOID BREATHING VAPOR. AVOID LIQUID
    CONTACT WITH EYES & SKIN. USE WITH SUFFICIENT VENTILATION. CONTACT
    WITH CHLORINE OR OTHER STRONG OXIDIZERS SHOULD BE AVOIDED. STORE IN
    CLEAN, DRY AREA. DO NOT HEAT  ABOVE 52C (125F).
Other Precautions:CONTACT OF WELDING OR SOLDERING TORCH FLAMES WITH
    HIGH CONCENTRATION OF REFRIGERANT CAN RESULT IN VISIBLE CHANGES IN
    SIZE & COLOR OF TORCH FLAMES. THIS EFFECT WILL ONLY OCCUR IN
    CONCENTRATIONS WELL AB OVE RECOMMENDED EXPOSURE LIMIT. THEREFORE
    STOP ALL WORK & VENTILATE TO DISPERSE VAPORS BEFORE USING  OPEN
    FLAMES.

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

Respiratory Protection:UNDER NORMAL MANUFACTURING CONDITONS NO
    RESPIRATORY PROTECTION IS REQUIRED WHEN USING PRODUCT.
    SELF-CONTAINED BREATHING APPARATUS REQUIRED IF LARGE RELEASES
    OCCURS.
Ventilation:LOCAL EXHAUST SHOULD BE USED IF LARGE AMOUNTS ARE RELEASED.
    MECHANICAL VENTILATION SHOULD BE USED IN LOW OR ENCLOSED PLACES.
Protective Gloves:IMPERVIOUS GLOVES.
Eye Protection:CHEM SPLASH GOGGLES.
Other Protective Equipment:NONE SPECIFIED BY MANUFACTURER.
Work Hygienic Practices:NONE SPECIFIED BY MANUFACTURER.
