IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. The substance can be absorbed into the body by inhalation and
by ingestion.
Physical dangers
Inhalation risk
The vapour is heavier than air. As a result of flow, agitation, etc.,
electrostatic charges can be generated. A harmful contamination of the air can be reached rather quickly
on evaporation of this substance at 20/C.
Chemical dangers
Effects of short-term exposure
On contact with hot surfaces or flames this substance
decomposes forming toxic and corrosive fumes (phosgene, The substance is irritating to the eyes and the skin. Swallowing
hydrogen chloride). The substance decomposes on contact with the liquid may cause aspiration into the lungs with the risk of
strong alkali producing dichloroacetylene, which increases fire chemical pneumonitis. The substance may cause effects on the

decomposed by light in presence of moisture, with formation of
corrosive hydrochloric acid. Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis.
Occupational exposure limits The substance may have effects on the central nervous system,

PHYSICAL PROPERTIES
Boiling point: 87/C Relative vapour density (air = 1): 4.5
Melting point: -73/C Relative density of the vapour/air-mixture at 20/C (air = 1): 1.3
Relative density (water = 1): 1.5 Auto-ignition temperature: 410/C
Solubility in water, g/100 ml at 20/C: 0.1 Explosive limits, vol% in air: 8-10.5
Vapour pressure, kPa at 20/C: 7.8 Octanol/water partition coefficient as log Pow: 2.42
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms. The substance may cause long-term effects in the aquatic environment.
NOTES
Combustible vapour/air mixtures difficult to ignite, may be developed under certain conditions.
Use of alcoholic beverages enhances the harmful effect.
Depending on the degree of exposure, periodic medical examination is suggested.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency
Response.
