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

LD50 LC50 Mixture:IHL-RAT LC50 IS 25PPH/4HOURS
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 AND MAY CAUSE HEART IRREGULARITIES,
    UNCONSCIOUSNESS OR DEATH. INTENTIONAL MISUSE OR DELIBERATE
    INHALATION MAY CAUSE DEATH WITHOUT WARNING. VAPOR R EDUCES OXYGEN
    AVAILABLE FOR BREATHING AND IS HEAVIER THAN AIR. LIQUID CONTACT CAN
    CAUSE FROSTBITE.
Effects of Overexposure:NERVOUS SYSTEM DEPRESSION, DIZZINESS, HEADACHE,
    CONFUSION, INCOORDINATION, AND LOSS OF CONSCIOUSNESS. HIGHER
    EXPOSURES MAY CAUSE ALTERATION OF THE HEART'S ELECTRICAL ACTIVITY
    WITH IRREGULAR PULSE, PAL PITATIONS, OR INADEQUATE CIRCULATION; OR
    FATALITY FROM GROSS OVEREXPOSURE. SKIN CONTACT WITH LIQUID MAY
    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 EXCESSIVE EXPOSURES.

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

First Aid:EYES: FLUSH WITH LARGE AMOUNTS OF WATER. GET MEDICAL
    ATTENTION. SKIN: FLUSH AREA WITH LARGE AMOUNTS OF WATER. TREAT FOR
    FROSTBITE IF NECESSARY BY GENTLY WARMING AFFECTED AREA. INHALATION:
    MOVE TO FRES H AIR. IF NOT BREATHING GIVE CPR. IF BREATHING
    DIFFICULT GIVE OXYGEN. GET MEDICAL ATTENTION. INGESTION: NOT
    CONSIDERED A POTENTIAL ROUTE OF EXPOSURE. HOWEVER, IF SWALLOWED GET
    MEDICAL ATTENTION.

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

Flash Point Method:TOC
Flash Point:NONE
Lower Limits:NONE
Upper Limits:NONE
Extinguishing Media:AS APPROPRIATE FOR COMBUSTABLES IN AREA. OTHER
    BURNING MATERIAL MAY CAUSE PRODUCT TO BURN WEAKLY.
Fire Fighting Procedures:USE WATER SPRAY OR FOG TO COOL CONTAINERS.
    SELF-CONTAINED BREATHING APPARATUS IS REQUIRED IF CYLINDERS RUPTURE
    OR CONTENTS ARE RELEASED UNDER FIRE CONDITIONS.
Unusual Fire/Explosion Hazard:CYLINDERS ARE EQUIPPED WITH PRESSURE AND
    TEMPERATURE RELIEF DEVICES BUT MAY RUPTURE UNDER FIRE CONDITIONS.
    DECOMPOSITION MAY OCCUR.

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

Spill Release Procedures:VENTILATE AREA-ESPECIALLY LOW PLACES WHERE
    HEAVY VAPORS MIGHT COLLECT. REMOVE OPEN FLAMES. USE PERSONAL
    PROTECTIVE EQUIPMENT DURING CLEAN UP. USE SELF-CONTAINED BREATHING
    APPARATUS FOR LARGE SPILLS.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

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

Handling and Storage Precautions:STORE CONTAINERS IN CLEAN, COOL, DRY,
    WELL VENTILATED AREA. DO NOT HEAT ABOVE 125F. PROTECT CONTAINER AND
    ITS FITTINGS FROM PHYSICAL DAMAGE.
Other Precautions:STORAGE IN SUBSURFACE LOCATIONS SHOULD BE AVOIDED.

=============  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 A LARGE RELEASE
    OCCURS.
Ventilation:NORMAL VENTILATION IS GENERALLY ADEQUATE. USE LOCAL EXHAUST
    FOR LARGE RELEASES AND MECHANICAL VENTILATION IN LOW PLACES.
Protective Gloves:IMPERVIOUS GLOVES WHEN HANDLING LIQUIDS.
Eye Protection:SPLASH GOGGLES WHEN HANDLING LIQUIDS.
Other Protective Equipment:NONE SPECIFIED BY MANUFACTURER.
Work Hygienic Practices:WASH AFTER HANDLING AND BEFORE EATING,
    DRINKING, OR SMOKING. LAUNDER CONTAMINATED CLOTHING BEFORE REUSE.
Supplemental Safety and Health
EXCESSIVE VAPORIZATION CAN DEPLETE/REPLACE OXYGEN NEEDED FOR BREATHING.
    THIS IS A MAJOR HAZARD IN CONFINED/ENCLOSED SPACES AND AREAS WITH
    LITTLE VENTILATION. FREON 22 SHOULD NOT BE MIXED WITH AIR FOR  LEAK
    TESTING. IT SHOULD NOT BE USED OR ALLOWED TO BE PRESENT WITH HIGH
    CONCENTRATIONS OF AIR ABOVE ATMOSPHERIC PRESSURE.
