Prevention
|
First Aid/
Fire Fighting
|
|
FIRE
|
Highly flammable.
|
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 CHARACTERISTIC 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 can form explosive peroxides.
The substance, as a liquid or vapour, can readily polymerize.
Reacts violently with oxidants and acids
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour.
Inhalation Risk:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance may cause effects on the central nervous system
, resulting in unconsciousness.
Effects of Long-Term or Repeated Exposure:
