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.
|
Foam,
alcohol-resistant foam,
powder,
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 mixes well with air, explosive mixtures are easily formed.
As a result of flow, agitation, etc., electrostatic charges can be generated.
Chemical Dangers:
The substance decomposes
on heating or
on burning
producing
irritating fumes
.
Reacts violently with strong oxidants.
Occupational Exposure Limits:
TLV not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
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 vapour
is strongly irritating to
the eyes
and
the respiratory tract
.
The substance
is irritating to
the skin
.
The substance may cause effects on the central nervous system.
Exposure at high level may result in unconsciousness.
Effects of Long-Term or Repeated Exposure:
