PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance OILY COLOURLESS-TO-YELLOW LIQUID WITH PUNGENT ODOUR. Physical dangers Chemical dangers Decomposes on heating. This produces phosgene. Decomposes on contact with water. This produces toxic and corrosive fumes including hydrogen chloride (see ICSC 0163). Attacks many metals in the presence of water or moist air.	Formula: C₈H₇ClO₂ Molecular mass: 170.6 Decomposes at >100°C Melting point: 0°C Relative density (water = 1): 1.20 Solubility in water: reaction Vapour pressure, kPa at 85-87°C: 0.009 Relative vapour density (air = 1): 1 Flash point: 80.0°C c.c.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion. Effects of short-term exposure Lachrymation. The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the aerosol may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated.	Inhalation risk A harmful concentration of airborne particles can be reached quickly on spraying. Effects of long-term or repeated exposure

EXPOSURE & HEALTH EFFECTS

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

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly on spraying.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT

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.
