Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour.
Inhalation Risk:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
irritates the eyes, the skin and the respiratory tract.
The substance may cause effects on the central nervous system.
Exposure could cause lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
