SAFETY DATA SHEET R134a 1. CHEMICAL PRODUCT AND COMPANY IDENTIFICATION Product name R134a Synonyms HFC 134a; 1,1,1,2-tetrafluoroethane Chemical Formula CH2 –F-CH3 CAS No 811-97-2 Use of Substance Industrial uses as refrigerant, blowing agent, propellant and solvent. Manufacturer Juhua Group Corporation No.
. HAZARDS IDENTIFICATION Labeling Chemical Name CAS No. R134a 811-97-2 Classification Code H-code Signal Word Press. Gas H 280 Warning Hazard Pictogram Classification of the substance Press. Gas : Gases under pressure (Liquefied gas) Hazard Statement H 280 : Contains gas under pressure; may explode if heated. Precautionary Statement OSHA H01 - : May displace oxygen and cause rapid suffocation. CGA HG01 – : May cause frostbite.
52 oC (125oF). Other Hazards CGA-PG05 : Use a back flow preventive device in the piping. CGA-PG06 : Close valve after each use and when empty. CGA-PG27 : Read and follow the Safety Data Sheet (SDS) before use. OSHAPG01 : DO NOT REMOVE THIS PRODUCT LABEL (or equivalent wording). Contact with liquid or cold vapor can cause frostbite. Low acute toxicity. High exposures may cause an abnormal heart rhythm and prove suddenly fatal. Very high concentrations may cause anesthetic affects and asphyxiation.
. FIRST AID MEASURES Eye Contact Contact with liquid or cold vapor can cause frostbite. Immediately flush with water for at least 15 minutes, opening eyelids to ensure flushing. Get medical attention if symptoms occur. Inhalation Victims should be assisted to an uncontaminated area is most important. Move exposed person to fresh air. If not breathing, provide artificial respiration or oxygen by trained personnel. In the event of cardiac arrest apply external cardiac massage.
Most important symptoms and effects, both acute and delayed High concentrations may cause asphyxiation. Symptoms may include loss of mobility/ consciousness. Victim may not be aware of asphyxiation. As asphyxiation progresses, nausea, vomiting, prostration, and loss of consciousness may result, eventually leading to convulsions, coma, and death. 5. FIRE FIGHTING MEASURES Suitable extinguishing media Use an extinguishing agent suitable for the surrounding fire.
. ACCIDENTAL RELEASE MEASURES Personal precautions Ensure suitable personal protection (including respiratory protection) during removal of spillages. Evacuate surrounding areas. Keep unnecessary and unprotected personnel from entering. Environmental precautions If safe to do so: isolate the source of the leak. Large spillages: Ventilate area. Contain spillages with sand, earth or any suitable adsorbant material. Try to stop release.
. HANDLING AND STORAGE Precaution for safe handling Avoid inhalation of high concentrations of vapors. Atmospheric level should be controlled in compliance with the occupational exposure limit. Atmospheric concentrations well below the occupational exposure limit can be achieved by good occupational hygiene practice. The vapor is heavier than air, high concentrations may be produced at low levels where general ventilation is poor.
. EXPOSURE CONTROLS/PERSONAL PROTECTION Control parameters Exposure Limit: OSHA-PEL Chemical Name R134a (1,1,1,2Tetrafluoroethane) Appropriate controls engineering Personal protection equipment Eight-hour time-weighted airborne concentration ppm - average mg/m3 - Use local exhaust and general ventilation systems. Engineering control measures are preferred to reduce oxygen depleted atmospheres. General methods include force-draught ventilation, separate from other exhaust ventilation systems.
. PHYSICAL AND CHEMICAL PROPERTIES Appearance : Colorless, Liquefied gas Odour : Slightly ethereal. . Odour threshold : Odour threshold is subjective and inadequate to warn for over exposure. pH : Not applicable Melting point / Freezing point : -101 oC Boiling point : -26.5 oC Flash point : Not applicable Evaporation rate : Not available Flammability : Not available .
. STABILITY AND REACTIVITY Reactivity No reactivity hazard other than the effects described in subsections below. Chemical Stability Stable. . Possibility of hazardous reactions Certain mixtures of HFCs and chlorine may be flammable or reactive under certain conditions. Can react violently if in contact with alkali metals and alkaline earth metals - sodium, potassium, barium. Condition to avoid Keep away from heat/sparks/open flames/hot surfaces – No smoking.
