ANTIMONY TRICHLORIDE

ICSC: 1224

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS HYGROSCOPIC CRYSTALS WITH PUNGENT ODOUR. Physical dangers Chemical dangers Decomposes on heating. This produces toxic fumes including chlorine and antimony oxides. Reacts with water. This produces heat, hydrogen chloride (see ICSC 0163) and antimony oxychloride. Attacks many metals in the presence of water. Aluminium burns in antimony trichloride vapour.	Formula: SbCl₃ Molecular mass: 228.1 Boiling point: 223.5°C Melting point: 73°C Density: 3.14 g/cm³ Solubility in water, g/100ml at 25°C: 10 Vapour pressure, Pa at 49°C: 133

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion. Effects of short-term exposure The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated.	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 long-term or repeated exposure The substance may have effects on the cardiovascular system.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion.

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated.

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 long-term or repeated exposure
The substance may have effects on the cardiovascular system.

OCCUPATIONAL EXPOSURE LIMITS
TLV: (as Sb): 0.5 mg/m³, as TWA. MAK: carcinogen category: 2; germ cell mutagen group: 3A

ENVIRONMENT
The substance is toxic to aquatic organisms.

NOTES
Depending on the degree of exposure, periodic medical examination is suggested. 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 by an authorized person, should be considered.
