Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air.
Chemical Dangers:
Reacts with strong oxidants.
Occupational Exposure Limits:
TLV not established.
MAK: IIb (not established but data is available) (DFG 2008).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation.
Inhalation Risk:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C
; on spraying or dispersing, however, much faster
.
Effects of Short-Term Exposure:
The substance
irritates
the eyes,
the skin and
the respiratory tract.
Effects of Long-Term or Repeated Exposure:
