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

Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:BREATHING HIGH CONCENTRATIONS OF THIS
    PRODUCT CAN CAUSE LIGHT HEADEDNESS, GIDDINESS, SHORTNESS OF BREATH,
    POSSIBLE NARCOSIS, POSSIBLE CARDIAC IRREGULARITIES, UNCONSCIOUSNESS
    OR DEATH. LIQUID CONTACT C AN CAUSE FROSTBITE.
Effects of Overexposure:INHALATION: VAPOR IS HEAVIER THAN AIR AND CAN
    CAUSE SUFFOCATION BY REDUCING OXYGEN AVAILABLE FOR BREATHING.
Medical Cond Aggravated by Exposure:CARDIOVASCULAR DISEASE-OVEREXPOSURE
    CAN CAUSE CARDIAC IRREGULARITIES.

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

First Aid:INHALE: REMOVE TO FRESH AIR, CALL DR. NOT BREATHING, GIVE
    CPR, PREFERABLY MOUTH-TO-MOUTH. BREATHING DIFFICULT, GIVE OXYGEN.
    DO NOT GIVE EPINEPHRINE/SIMILAR DRUGS. EYE/SKIN: FLUSH W/WATER.
    CALL DR. TRE AT FOR FROSTBITE IF NECESSARY. BECAUSE OF A POSSIBLE
    RISK OF ELICITING CARDIAC DYSRYTHMIAS, CATECHOLAMINE DRUGS, SUCH AS
    EPINEPHRINE, SHOULD BE CONSIDERED LAST RESORT IN LIFE THREATENING
    EMERGENCIES.

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

Flash Point Method:TOC
Flash Point:NA
Autoignition Temp:Autoignition Temp Text:1170 F
Extinguishing Media:NONFLAMMABLE
Fire Fighting Procedures:OTHER BURNING MAT'L MAY CAUSE FREON 22 TO BURN
    WEAKLY. EXTINGUISHANT FOR OTHER BURNING MAT'L IN AREA IS SUFFICIENT
    TO STOP BURNING. SCBA MAY BE REQUIRED. IF
Unusual Fire/Explosion Hazard:CYLINDERS ARE EQUIPPED WITH PRESSURE AND
    TEMPERATURE RELIEF DEVICES BUT STILL 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. EVACUATE ALL
    PERSONNEL FROM AFFECTED AREA. IN CASE OF EMERGENCY, CALL CHEMTREC

Other Precautions:CYLINDERS RUPTURE OR CONTENTS ARE RELEASED UNDER FIRE
    CONDITIONS, FREON 22 CAN BE DECOMPOSED BY HIGH TEMPERATURE FORMING
    HYDROCHLORIC AND HYDROFLUORIC ACIDS AND POSSIBLE CARBONYL HALIDES.

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

Respiratory Protection:NORMAL VENTILATION FOR STANDARD MANUFACTURING
    PROCEDURES IS GENERALLY ADEQUATE. LOCAL EXHAUST SHOULD BE USED WHEN
    LARGE AMOUNTS ARE RELEASED. MECHANICAL VENTILATION SHOULD BE USED
    IN LOW PLACES.
Ventilation:POSITIVE PRESSURE AIR LINE WITH MASK OR SCBA SHOULD BE
    AVAILABLE FOR EMERGENCY USE. HOOD WITH FORCED VENTILATION.
Protective Gloves:LINED BUTYL GLOVES
Eye Protection:CHEMICAL SPLASH GOGGLES
