International Chemical Safety Cards TRIFLUOROCHLOROETHYLENE ICSC: 0685 Chlorotrifluoroethylene Trifluorovinyl chloride C2ClF3 Molecular mass: 116.47 (cylinder) ICSC #    0685 CAS #     79-38-9 RTECS # KV0525000 UN #        1082 March 04, 2002 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Flammable. NO open flames, NO sparks, and NO smoking. Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out; in other cases extinguish with water spray,alcohol-resistant foam,dry powder,carbon dioxide. EXPLOSION Gas/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. EXPOSURE  •INHALATION Dizziness. Nausea. Ventilation, local exhaust, or breathing protection. Fresh air, rest.  •SKIN ON CONTACT WITH LIQUID: FROSTBITE. Cold-insulating gloves. ON FROSTBITE: rinse with plenty of water, do NOT remove clothes.  •EYES Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Ventilation. Remove all ignition sources. Remove vapour with fine water spray. Personal protection: self-contained breathing apparatus. Fireproof. Cool.

International Chemical Safety Cards TRIFLUOROCHLOROETHYLENE ICSC: 0685 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS , ODOURLESS GAS PHYSICAL DANGERS: The gas mixes well with air, explosive mixtures are formed easily. CHEMICAL DANGERS: On combustion, forms toxic and corrosive gasesincludinghydrogen chloride (ICSC0163)andhydrogen fluoride (ICSC0283). OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: On loss of containment, a harmful concentration of this gas in the air will be reached very quickly. EFFECTS OF SHORT-TERM EXPOSURE: The liquid may cause frostbite. The substance may cause effects on the kidneys. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: -28°C Melting point: -158°C Relative density (water = 1): 1.3 Vapour pressure, kPa at 25°C: 612 Relative vapour density (air = 1): 4.02 Flash point: -27.8°C Explosive limits, vol% in air: 24-40.3 ENVIRONMENTAL DATA This substance may be hazardous in the environment; special attention should be given to its impact on the ozone layer. N O T E S An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Card has been partly updated in April 2005. See flash point.
