SULPHURYL CHLORIDE

ICSC: 0198

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS-TO-YELLOW LIQUID WITH PUNGENT ODOUR. TURNS YELLOW ON EXPOSURE TO AIR OR LIGHT. Physical dangers The vapour is heavier than air. Chemical dangers Decomposes under the influence of moist air. This produces chlorine, sulfur oxide, sulfuric acid and hydrogen chloride. Reacts violently with water. Attacks many metals in the presence of water.	Formula: SO₂Cl₂ Molecular mass: 134.96 Boiling point: 69.1°C Melting point: -54.1°C Relative density (water = 1): 1.67 Solubility in water: reaction Vapour pressure, kPa at 20°C: 14.8 Relative vapour density (air = 1): 4.65 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.5

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour. Effects of short-term exposure The substance is corrosive to the eyes, skin and respiratory tract. Inhalation of the vapour may cause lung oedema. See Notes. The substance may cause effects on the respiratory tract. Exposure could cause death. The effects may be delayed. Medical observation is indicated.	Inhalation risk A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour.

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

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
This substance may be hazardous to the environment. Special attention should be given to water quality.

NOTES
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. Do NOT take working clothes home. Do NOT use in the vicinity of a fire or a hot surface, or during welding.
