International Chemical Safety Cards CARBON TETRABROMIDE ICSC: 0474 Tetrabromomethane CBr4 Molecular mass: 331.6 ICSC #    0474 CAS #     558-13-4 RTECS # FG4725000 UN #        2516 March 26, 1999 Peer reviewed 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: all extinguishing agents allowed. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE!  •INHALATION Cough. Drowsiness. Dullness. Laboured breathing. Shortness of breath. Sore throat. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Pain. Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.  •EYES Redness. Pain. Blurred vision. Severe deep burns. Face shield, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Diarrhoea. Dullness. Sore throat. (See Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: P2 filter respirator for harmful particles, dust). Well closed. Do not transport with food and feedstuffs. Marine pollutant. R: S: UN Hazard Class: 6.1 UN Packing Group: III SEE IMPORTANT INFORMATION ON BACK ICSC: 0474 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994.

International Chemical Safety Cards CARBON TETRABROMIDE ICSC: 0474 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS CRYSTALS PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic and corrosive fumes. Reacts withalkali metals causing explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.1 ppm (as TWA); 0.3 ppm (as STEL) (ACGIH 1998). OSHA PEL: none NIOSH REL: TWA 0.1 ppm (1.4 mg/m3) ST 0.3 ppm (4 mg/m3) NIOSH IDLH: No data ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and by ingestion. INHALATION RISK: A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: Tear drawing. The substance is corrosive to the eyes and irritates the skin and the respiratory tract. The substance may cause effects on the lungs, liver, and kidneys. Exposure to high concentrations may result in unconsciousness. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the liver. PHYSICAL PROPERTIES Boiling point: 190°C Melting point: 90°C Relative density (water = 1): 3.42 Solubility in water: none Vapour pressure, kPa at 96°C: 5.33 Relative vapour density (air = 1): 11.4 ENVIRONMENTAL DATA N O T E S Do NOT take working clothes home. Do NOT use in the vicinity of a fire or a hot surface, or during welding. Transport Emergency Card: TEC (R)-61G11c ADDITIONAL INFORMATION ICSC: 0474 CARBON TETRABROMIDE (C) IPCS, CEC, 1994
