International Chemical Safety Cards TRICHLOROFLUOROMETHANE ICSC: 0047 Trichloromonofluoromethane Fluorotrichloromethane CFC 11 R 11 CCl3F Molecular mass: 137.4 ICSC #    0047 CAS #     75-69-4 RTECS # PB6125000 March 07, 2002 Peer reviewe TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: use appropriate extinguishing media. EXPLOSION In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE  •INHALATION Cardiac arrhythmia. Confusion. Drowsiness. Unconsciousness. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.  •SKIN ON CONTACT WITH LIQUID: FROSTBITE. Dry skin. Cold-insulating gloves. ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.  •EYES Redness. Pain. 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. Separated from incompatible materials . See Chemical Dangers. Cool. R: S: SEE IMPORTANT INFORMATION ON BACK ICSC: 0047 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards TRICHLOROFLUOROMETHANE ICSC: 0047 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS GAS OR HIGHLY VOLATILE LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The gas is heavier than air. The vapour is heavier than air and may accumulate in low ceiling spaces causing deficiency of oxygen. CHEMICAL DANGERS: On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive gases(hydrogen chloride ICSC 0163,phosgene ICSC 0007,hydrogen fluoride ICSC 0283,carbonyl fluoride ICSC 0633). Reacts with powders of aluminium, zinc, magnesium and lithium shavings; granular barium. OCCUPATIONAL EXPOSURE LIMITS: TLV: 1000 ppm (Ceiling value); A4; (ACGIH 2004). MAK: 1000 ppm; 5700 mg/m³; Peak limitation category: II(2); Pregnancy risk group: C; (DFG 2004). OSHA PEL: TWA 1000 ppm (5600 mg/m3) NIOSH REL: C 1000 ppm (5600 mg/m3) NIOSH IDLH: 2000 ppm ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: On loss of containment this liquid evaporates very quickly displacing the air and causing a serious risk of suffocation when in confined areas. EFFECTS OF SHORT-TERM EXPOSURE: The liquid may cause frostbite. The substance may cause effects on the cardiovascular system and central nervous system , resulting in cardiac disorders and central nervous system depression. Exposure could cause lowering of consciousness. See Notes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin. PHYSICAL PROPERTIES Boiling point: 24°C Melting point: -111°C Relative density (water = 1): 1.49 Solubility in water, g/100 ml at 20°C: 0.1 Vapour pressure, kPa at 20°C: 89.0 Relative vapour density (air = 1): 4.7 Relative density of the vapour/air-mixture at 20°C (air = 1): 4.4 Octanol/water partition coefficient as log Pow: 2.53 ENVIRONMENTAL DATA This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer. N O T E S High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area. The occupational exposure limit value should not be exceeded during any part of the working exposure. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT use in the vicinity of a fire or a hot surface, or during welding. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state. Freon 11, Frigen 11, Halon 11 are trade names. Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
