INGREDIENT NAME WEIGHT% CAS NUMBER

1,1,1,2-Tetrafluoroethane 100 811-97-2

Trace impurities and additional material names not listed above may also appear in section 15 toward the end of the MSDS these materials may be lised for local”right-to-know”compliance and for other reasons.


3HAZARDS IDENTIFICATION

Emergency overview: Colorless, volatile liquid with ethereal and faint sweetish odor. Non-flammable material. Overexposure may cause dizziness and loss of concentration. At higher levels, CNS depression and cardiac arrhythmia may result from exposure. Vapors displace air and can cause asphyxiation in confined spaces. at higher temperatures,(>250℃),decomposition product may include hydrofluoric acid(HF) and carbonyl halides.

POTENTIAL HEALTH HAZARDS


SKIN : Irritation would result from a defeating action on tissue, liquid with contact could cause frostbite

EYES : Liquid contact can cause severe irritation and frostbite ,mist may irritate.

INHALATION:R-134a is low in acute toxicity in animals. When oxygen levels in air are reduced ot 12-14%by displacement, symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper respiration will occur at high levels, cardiac arrhythmia may occur

INGESTION: Ingestion is unlikely because of the low boiling point of the material. Should it occur, discomfort in the gastrointestinal tract from rapid evaporation of the material and consequent evolution of gas would result some effect of inhalation and skin exposure would be expected.

Delayed effects : None known

Ingredients name: No ingredients listed in this section.


4 FIRST AID MEASURES:

SKIN: 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.


Eyes: Immediately flush eyes with large amounts of water for at least 15minute (in case of frostbite, water should be lukewarm, not hot) lifting eyelids occasionally to facilitate irrigation. get medical attention if symptoms persist.

Inhalation: Immediately remove to fresh air. if breathing has stopped, give artificial respiration. Use oxygen as required .provided a qualified operator is available. get medical attention immediately, do not give epinephrine (adrenaline).

Ingestion: ingestion unlikely because of the physical properties and is not expected to be hazardous, do not induce vomiting unless instructed to do so by a physician.

Advice to physician: because of the possible disturbances of cardiac rhythm, catechlolamine drugs, such as epinephrine, should be used with special caution and only in situations of emergency life support treatment of overexposure should be directed at the control of symptoms and the clinical

5 FIRE FIGHTING MEASURES:

FLAMMABLE PROPERTIES


Flash point: gas, not applicable per DOT regulations

Flash point method: not applicable

Auto ignition temperature: >750℃

Upper flame limit (volume % in air): None

Lower flame limit (volume % in air): None base on ASHRAE standard 34 with match ignition

Flame Propagation rate (solids): not applicable

OSHA Flammability class: Not applicable

Extinguishing media:

Use any standard agent- choose the one most appropriate for type of surrounding fire(material itself is not flammable)


Unusual fire and explosion hazards:

R134a is not flammable at ambient temperatures and atmospheric pressure, however, this material will become combustible when mixed with air under pressure and exposed to strong to ignition sources.

Contact with certain reactive metals may result in formation or exothermic reactions under specific conditions (e.g. very high temperatures and / or appropriate pressures).


6ACCIDENTAL RELEASE MEASURE

In case of spill or other release :(always wear recommended personal protective equipment)

Evacuate unprotected personnel. Protected personnel should remove ignition sources and shut off leak ,if without risk and provide ventilation unprotected personnel should not returm until air has been tested and determined safe including low-lying areas.
