=============  Composition/Information on Ingredients  =============

Ingred Name:1,1,1,2-TETRAFLUOROETHANE
CAS:811-97-2
= Wt:100.
Other REC Limits:1000 PPM (WEEL)

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

LD50 LC50 Mixture:LC50 RAT (4-HR): >500,000 PPM
Health Hazards Acute and Chronic:EYE EFFECTS: RAPID VOLATILIZATION OF
    LIQUID MAY CAUSE FROSTBITE IF LIQUID IS APPLIED TO THE EYES. SKIN
    EFFECTS: SLIGHT IRRITANT, CONTACT WITH LIQUID MAY CAUSE FROSTBITE.
    INHALATION: NORMALLY IS PRACTI CALLY NON-TOXIC IF INHALED. HOWEVER,
    EXPOSURE TO HIGH CONCENTRATIONS MAY AFFECT THE NERVOUS SYSTEM &
    PRODUCE A RAPID ANESTHETIC EFFECT. VAPOR IS HEAVIER IN AIR &
    DISPLACES AIR IN CONFINED SPACES THERE FORE REDUCING OXYGEN
    AVAILABLE FOR BREATHING. INHALATION MAY ALSO CAUSE AN INCREASE IN
    HEART SENSITIVITY TO ADRENILINE WHAICH MAY PRODUCE IRREGULAR
    HEARTBEATS (CARDIAC ARRYTHMIAS), RAPID HEARTBEAT (TA CHYCARDIA) AND
    REDUCED HEART FUNCTION.
Explanation of Carcinogenicity:NOT PROVIDED BY MANUFACTURER
Effects of Overexposure:INHALATION (OXYGEN DEFICIENCY): HEADACHE,
    DIZZINESS, DROWSINESS, CYANOSIS, LACK OF MUSCLE CONTROL FOLLOWED BY
    COLLAPSE. PROLONGED EXPOSURE TO OXYGEN DEFICIENT ATMOSPHERE MAY BE
    FATAL.
Medical Cond Aggravated by Exposure:WORKERS WITH HEART DISEASE OR
    COMPROMISED HEART FUNCTION SHOULD ONLY HAVE LIMITED EXPOSURE TO
    THIS MATERIAL.

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

First Aid:INGESTION: N/A-PRODUCT IS A GAS AT AMBIENT CONDITIONS. EYE:
    IF IN EYES, IMMEDIATELY FLUSH WITH PLENTY OF WATER FOR AT LEAST 15
    MINUTES. GET MEDICAL ATTENTION. DERMAL: FLUSH EXPOSED SKIN WITH
    LUKEWARM  WATER (NOT HOT)-OR USE OTHER MEANS TO WARM SKIN SLOWLY.
    GET MEDICAL ATTENTION IF FROSTBITTEN BY LIQUID OR IF IRRITATION
    OCCURS. INHALATION: IF INHALED, REMOVE TO FRESH AIR. IF NOT
    BREATHING, GIVE ARTI FICIAL RESPIRATION. IF BREATHING IS DIFFICULT
    GIVE OXYGEN. GET MEDICAL ATTENTION. DO NOT GIVE ADRENALINE,
    EPINEPHRINE OR SIMILAR DRUGS FOLLOWING EXPOSURE TO THIS PRODUCT.

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

Lower Limits:NA
Upper Limits:NA
Extinguishing Media:USE EXTINGUISHING MEDIA APPROPRIATE TO SURROUNDING
    FIRE CONDITIONS.
Fire Fighting Procedures:WEAR SELF-CONTAINED BREATHING APPARATUS IF
    FIGHTING FIRES NEAR THIS PRODUCT DUE TO TOXICITY OF THERMAL
    DECOMPOSITION PRODUCTS. KEEP CONTAINERS COOL.
Unusual Fire/Explosion Hazard:HFC 134A IS NOT FLAMMABLE AT AMBIENT
    TEMPERATURES  & ATMOSPHERIC PRESSURE. HOWEVER, THIS MATERIAL WILL
    BECOME COMBUSTIBLE WHEN MIXED WITH AIR UNDER PRESSURE & EXPOSED TO
    STRONG IGNITION SOURCES. LIQUI D & GAS UNDER PRESSURE, OVERHEATING
    OR OVERPRESSURIZING MAY CAUSE GAS RELEASE OR VIOLENT CYLINDER
    BURSTING.

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

Spill Release Procedures:REMOVE OR EXTINGUISH IGNITION OR COMBUSTION
    SOURCES. EVACUATE ENCLOSED SPACES UNTIL GAS IS DISPERSED. KEEP
    UPWIND. STOP LEAK IF POSSIBLE WITHOUT RISK. DISPERSE GAS WITH
    FLOOR-LEVEL FORCED-AIR VENTILAT ION. EXHAUST VAPORS OUTDOORS.
    REMOVE ALL FLAMES, HEATING ELEMENTS AND GAS ENGINES. WASH
    CONTAIMINATED CLOTHES BEFORE USE. DESTROY CONTAMINATED SHOES.
Neutralizing Agent:NOT PROVIDED BY MANUFACTURER

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

Handling and Storage Precautions:DO NOT GET IN EYES, ON SKIN OR
    CLOTHING. DO NOT BREATHE VAPOR, MIST OR GAS. KEEP CONTAINER CLOSED.
    KEEP AWAY FROM HEAT, SPARKS AND FLAMES. STORE IN TIGHTLY CLOSED
    CONTAINER.
Other Precautions:EMPTY CONTAINER MAY CONTAIN HAZARDOUS RESIDUE. DO NOT
    DROP, REUSE OR REFILL CONTAINER. DO NOT SMOKE. READ LABEL BEFORE
    USE. DO NOT CUT, GRIND OR WELD ON OR NEAR CONTAINER DUE TO POSSIBLE
    TOXIC FUME GE NERATION. HFC 134A SHOULD NOT BE MIXED WITH AIR ABOVE
    ATMOSPHERIC PRESSURE FOR LEAK TESTING OR ANY O THER PURPOSE.

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

Respiratory Protection:USE NIOSH/MSHA APPROVED FULL FACE (TC-19C)
    SUPPLIED AIR RESPIRATOR OR SELF CONTAINED BREATHING APPARATUS WHERE
    AIRBORNE EXPOSURE IS LIKELY. IF USED, FULL FACEPIECE REPLACES NEED
    FOR CHEMICAL GOGGLES & /OR FACESHIELD, IF EXPOSURES CANNOT BE KEPT
    AT MINIMUM WITH ENGINEERING CONTROLS, USE NIOSH/MSHA APPROVED
    RESPRIRATORY EQUIPMENT AS NOTED.
Ventilation:INVESTIGATE ENGINEERING TECHNIQUES TO REDUCE EXPOSURES
    BELOW AIRBORNE EXPOSURE LIMITS. PROVIDE VENTILATION IF NECESSARY TO
    CONTROL EXPOSURE LEVELS BELOW
Protective Gloves:USE SYNTHETIC RUBBER GLOVES SUCH AS NEOPRENE.
Eye Protection:WEAR CHEMICAL GOGGLE
Other Protective Equipment:LINED GLOVES ARE RECOMMENDED FOR PROTECTION
    FROM COLD. HAVE EYE FLUSHING EQUIPMENT IMMEDIATELY AVAILABLE. WEAR
    APPROPRIATE CHEMICAL RESISTANT PROTECTIVE CLOTHING TO PREVENT SKIN
    CONTACT.
Work Hygienic Practices:AVOID BREATHING VAPOR, MIST, OR FUME
Supplemental Safety and Health
REPIRATORY PROTCTION CONTINUED: OBSERVE RESPIRATOR USE LIMITATIONS
    SPECIFIED BY NIOS/MSHA OR RESPIRATOR MANUFACTURER. FOR EMERGENCY &
    OTHER CONDITIONS WHERE THERE MAY BE A POTENTIAL FOR SIGNIFIGANT EX
    POSURE USE AN APPROVED FULL FACE POSITIVE PRESSURE AIRLINE WITH
    AUXILARY SELF-CONTAINED AIR SUPPLY.
