International Chemical Safety Cards ANTIMONY TRICHLORIDE ICSC: 1224 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS HYGROSCOPIC CRYSTALS , WITH PUNGENT ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumesincludingchlorineand antimony oxides. Reacts withwaterto produce heat, hydrogen chloride (see ICSC0163) and antimony oxychloride. Attacks many metals in the presence of water. Aluminium burns in antimony trichloride vapour. OCCUPATIONAL EXPOSURE LIMITS: TLV: (as Sb) 0.5 mg/m³ as TWA (ACGIH 2004). MAK: (as Sb) 0.5 mg/m³ (DFG 2003). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of the substance may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the cardiovascular system. PHYSICAL PROPERTIES Boiling point: 223.5°C Melting point: 73°C Density: 3.14 g/cm3 Solubility in water, g/100 ml at 25°C: 10 Vapour pressure, Pa at 49°C: 133 ENVIRONMENTAL DATA The substance is toxic to aquatic organisms. N O T E S C.I. 77056 is an alternative name. Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
