Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
Chemical Dangers:
The substance can presumably form explosive peroxides.
The substance decomposes
on burning
producing
toxic gases
and
irritating fumes
.
Occupational Exposure Limits:
TLV not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation.
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
.
Exposure at high levels could cause lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
