SECTION II 鈥? COMPOSITION/INFORMATION ON INGREDIENTS
Material CAS # %
1,1,1,2-Tetrafluoroethane 811-97-2 100%
SECTION III - HAZARDS IDENTIFICATION
Potential Health Effects:
Potential Health Effects 鈥? Inhalation of high concentrations of vapor is harmful and may cause irregular heart
beat unconsciousness or death. Intentional misuse or deliberate inhalation may cause death without warning.
Vapor reduces oxygen available for breathing and is heavier than air. Liquid contact can cause frostbite.
Human Health Effects 鈥? Overexposure by inhalation to very high concentrations may cause temporary alterations of
the heart鈥檚 electrical activity with irregular pulse, palpitations, or inadequate circulation. Skin contact may cause
frostbite.
Additional Health Effects 鈥? Increased susceptibility to the effects of this material may be observed in persons with
pre-existing disease of the: central nervous system, cardiovascular system.
Carcinogenicity Information 鈥? None of the components present in this material at concentrations equal to or greater
than 0.1% is listed by IARC, NTP, OSHA or ACGIH as a carcinogen.
SECTION IV - FIRST AID
Inhalation - If high concentrations are inhaled, immediately remove to fresh air. Keep person calm. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Call a physician.
Skin Contact 鈥? Promptly flush skin with water until all chemical is removed. If there is evidence of frostbite, bathe (do not
rub) with lukewarm (not hot) water. If water is not available, cover with a clean, soft cloth or similar covering. Get medical
attention if symptoms persist.
Eye Contact 鈥? Immediately flush eyes with large amounts of water for at least 15 minutes (in case of frostbit water should be
lukewarm, not hot) lifting eyelids occasionally to facilitate irrigation. Get medical attention if symptoms persist.
Ingestion - Ingestion is not considered a potential route of exposure.
Notes to Physicians - Because of possible disturbances of cardiac rhythm, catecholamine drugs, such as epinephrine,
should be used with special caution only in situations of emergency life support.

SECTION V - FIRE FIGHTING MEASURES Continued鈥︹??
Fire and Explosion Hazards: 鈥? Aerosol cans may erupt with force at temperatures above 49掳C (120掳F)
Decomposition may occur.
Note:
HFC-134a is not flammable in air temperatures up to 100掳C (212掳F) at atmospheric
pressure. However, mixtures of HFC-134a with high concentrations of air at elevated
pressure and/or temperature can become combustible in the presence of an ignition source.
HFC-134a can also become combustible in an oxygen enriched environment (oxygen
concentrations greater than that in air). Whether a mixture containing HFC-134a and air, or
HFC-134a in an oxygen enriched atmosphere become combustible depends on the inter-
relationship of : 1.The temperature 2. The pressure and 3. The proportion of oxygen in the
mixture. In general HFC-134a should not be allowed to exist with air above atmospheric
pressure or at high temperatures; or in an oxygen enriched environment. Experimental data
have also been reported which indicated combustibility of HFC-134a in the presence of
certain concentrations of chlorine.
Extinguishing Media - As appropriate for combustibles in area.
Hazardous Combustion Products - Smoke, fumes and oxides of carbon.
Special Fire Fighting Procedures - Cool aerosol cans with water spray. Self-contained breathing apparatus (SCBA)
may be required if aerosol cans rupture or release under fire conditions.
SECTION VI - ACCIDENTAL RELEASE MEASURES
Safeguards (Personnel) - NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL) sections before
proceeding with clean up. Use appropriate PERSONAL PROTECTIVE EQUIPMENT during clean up.
Ventilate area, especially low or enclosed places where heavy vapors might collect. Remove open flames. Use self-
contained breathing apparatus (SCBA) if large spill or leak occurs.
SECTION VII 鈥? HANDLING AND STORAGE
Handling (Personnel) - Use with sufficient ventilation to keep employee exposure below recommended limits.
Handling (Physical Aspects) - HFC-134a should not be mixed with air for leak testing or used for any other purpose above
atmospheric pressure. See Flammable Properties Section. Contact with chlorine or other strong oxidizing agents should also
be avoided.
Storage - Clean, dry area. Do not heat above 49掳C (120掳F).

SECTION IX 鈥? STABILITY AND REACTIVITY
Chemical Stability - Material is stable. However, avoid open flames and high temperatures.
Incompatibility with Other Materials - Incompatible with alkali or alkaline earth metal.
Decomposition - Decomposition products are hazardous. This material can be decomposed by high temperatures (open
flames, glowing metal surfaces, etc.) forming hydrofluoric acid and carbonyl fluoride.
Polymerization - Polymerization will not occur.
