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.
Chemical Dangers:
Reacts
violently with
strong oxidants
causing fire and explosion hazard.
Attacks many plastics and resins.
Occupational Exposure Limits:
TLV not established.
MAK not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.
Effects of Short-Term Exposure:
The substance
irritates
the eyes and
the respiratory tract.
Effects of Long-Term or Repeated Exposure:
|
|
