Health Hazards Acute and Chronic:SKIN-IRRITATION WOULD RESULT FROM A
DEFATTING ACTION ON SKIN. EYES-LIQUID CONTACT CAN CAUSE IRRITATION,
WHICH MAY BE SEVERE. MIST MAY IRRITATE. INHALATION-GENETRON 134A IS
A LOW ORDER ACUTE TOXICITY I N ANIMALS. WHEN OXYGEN LEVELS IN AIR
AREREDUCED TO 12-14% BY DISPLACEMENT SYMPTOMS OF ASPHYXIATION.,
LOSS OF COORDINATION, INCREASED PULSE RATE AND DEEPER RESPIRATION
WILL OCCUR. INGESTION-ALTHOUGH IN GESTION IS UNLIKELY, DISCOMFORT
IN THE GASTROINTESTINAL TRACT WOULD RESULT FROMRAPID EVAPORATION OF
THE MATERIAL AND CONSEQUENT ELEVATION OF GAS.
Explanation of Carcinogenicity:NONE.
Effects of Overexposure:INHALATION-AT HIGH LEVELS, CARDIAC ARRYTHMIA
MAY OCCUR. INGESTION-NECROSIS FROM FREEZING OF TISSUE COULD OCCUR.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MFG.

First Aid:SKIN-PROMPTLY FLUSH SKIN WITH WATER UNTIL ALL CHEMICAL IS
REMOVED. IF FROSTBITE, BATHE WITH LUKEWARM WATER. COVER WITH CLEAN,
SOFT CLOTH OR SIMILIAR COVERING. CALL A PHYSICIAN. EYE-FLUSH EYES
WITH LAR GE AMOUNTS OF WATER FOR 15 MIN, LIFTINGEYELIDS
OCCASIONALLY TO FACILITATE IRRIGATION. GET MEDICAL ATTENTION.
INHALE-REMOVE TO FRESH AIR. IF BREATHING SYOPS, GIVE ARTIFICIAL
RESPIRATION. USE OXYGEN AS REQUIRED, PROVIDED A QUALIFIED OPERATOR
IS AVAILABLE. CALL PHYSICIAN. DON'T GIVE EPINEPHRINE(ADRENALINE).
INGESTION-INGESTION IS UNLIKELY. DO NOT INDUCE VOMITING, UNLESS
INSTRUCTED TO DO SO BY A PHYSI CIAN.

Flash Point:NONE
Autoignition Temp:Autoignition Temp Text:>750C
Extinguishing Media:USE ANY STANDARD AGENT---CHOOSE THE ONE MOST
APPROPRIATE FOR TYPE OF SURROUNDING FIRE (MATERIAL ITSELF IS NOT
FLAMMABLE)
Fire Fighting Procedures:WEAR NIOSH-APPROVED SCBA FOR PROTECTION
AGAINST POSSBILE TOXIC DECOMPOSITION PRODUCTS.PROPER EYE/SKIN
PROTECTION. USE H2O SPRAY TO COOL CNTRS & SUPRRESS VAPORS.
Unusual Fire/Explosion Hazard:CONTACT W/CERTAIN REACTIVE METALS MAY
RESULT IN EXPLOSION OR EXOTHERMIC REACTIONS UNDER SPECIFIC
CONDITIONS(EG VERY HI TEMP &/OR APPROPRIATE PRESSURE).

Spill Release Procedures:EVACUATE UNPROTECTED PERSONNEL. PROTECTED
PERSONNEL SHOULD REMOVE FLAMES & SHUT OFF LEAK IF W/O RISK. PROVIDE
VENTILATION. UNPROTECTED PERSONNEL SHOULD NOT RETURN UNTIL AIR HAS
BEEN TESTED & DETERMINE D SAFE, PARTULARLY IN LOW-LYING AREAS.
Neutralizing Agent:NOT APPLICABLE.

Handling and Storage Precautions:STORE IN COOL, WELL-VENTILATED AREA OF
LOW FIRE RISK. PROTECT CYLINDER & FITTINGS FROM PHYSICAL DAMAGE.
STORAGE IN SUBSURFACE LOCATIONS SHOULD BE AVOIDED.
Other Precautions:CLOSE VALVE TIGHTLY AFT USE & WHEN EMPTY. AVOID
BREATH VAPORS & LIQUID CONTACT W/EYES/SKIN/CLOTH. DON'T PUNCTURE OR
DROP CYLINDER OR EXPOSE THEM TO OPEN FLAME OR EXCESSIVE HEAT. USE
AUTHORIZED CYLINDE R ONLY. FOLLOW STD SAFETY PRECAUT FOR HANDL/USE
CYL.

Respiratory Protection:NONE GENERALLY REQUIRED FOR ADEQUATELY
VENTILATED WORK SITUATIONS.FOR ACCIDENTAL OR NON-VENTILATED
SITUATIONS FROM ESTIMATED TLV TO 5000PPM USE NIOSH SCBA OR SUPPLIED
AIR RESP.FOR ESCAPE USE FORMER OR NIOSH GAS MASK W/ORG VAPOR
CANISTER.
Ventilation:PROVIDE LOCAL EXHAUST @ FILLING ZONES & AREAS WHERE LEAKAGE
IS PROBABLE. MECHANICAL (GENERAL) VENTILATION MAY BE ADEQUATE FOR
OTHERS.
Protective Gloves:IMPERVIOUS WITH PVA OUTER LAYER; NEOPRENE.
Eye Protection:SAFETY GLASSES, CHEMICAL SAFETY GOGGLES.
Other Protective Equipment:IMPERVIOUS SHOES/CLOTH WHERE LEAKAGE IS
PROBABLE & SHOULD BE THERMALLY INSULATED TO PREVENT FREEZING. NO
CONTACT LENSES.
Work Hygienic Practices:DON'T WEAR CNTCT LENSES.EYEWASH STATIONS,SAFETY
SHOWERS.OBSERVE ALL LABELED PRECAUTIONS. FORMAL ENTRY PROCEDURES
FOR TANK
Supplemental Safety and Health
TESTS SHOW THAT AN AIR-RICH MIXTURE W/ GENETRON 134A @ SLIGHTLY OVER
ATM PRESSURE IS COMBUSTIBLE WHEN EXPOSED TO AN EXPLODING COPPER
WIRE. NONEXPLOSIVE CONDITIONS MAY YIELD TOXIC &/OR CORROSIVE DECOMP
OSITION PRODUCTS.FIRST AID INGEST:UNLIKELY DUE TO PHYSICAL
PROPERTIES.INDUCE VOMITING ONLY UNDER MEDICAL SUPERVISION.
