Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Chemical Dangers:
The substance can form explosive peroxides.
Reacts
with
strong oxidants
causing fire and explosion hazard.

|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation and through the skin,
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
central nervous system
,
blood
,
kidneys
and
liver
.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
