First Aid/
Fire Fighting
|
|
FIRE
|
Highly flammable.
Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames, NO sparks, and NO smoking.
|
Powder, AFFF, foam, carbon dioxide.
|
|
Explosion
|
Vapour/air mixtures are explosive.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting.
Prevent build-up of electrostatic charges (e.g., by grounding).
Do NOT use compressed air for filling, discharging, or handling.
|
In case of fire: keep drums, etc., cool by spraying with water.

Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH PUNGENT ODOUR.
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
As a result of flow, agitation, etc., electrostatic charges can be generated.
Chemical Dangers:
The substance decomposes
on heating or
on burning
producing toxic and corrosive fumes including hydrogen chloride and phosgene.
Reacts slowly with water forming hydrochloric acid.
Reacts violently with oxidants and powdered metals
causing fire and explosion hazard.
Attacks aluminium and many plastics.
Occupational Exposure Limits:
TLV not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour and
by ingestion.
Inhalation Risk:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
irritates
the eyes,
the skin and
the respiratory tract.
The substance may cause effects on the nervous system.
Effects of Long-Term or Repeated Exposure:
