1,1,1,2-TETRAFLUOROETHANE

CAS: 811-97-2

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: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.

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.

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 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.

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.
