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 not or will only very slowly be reached 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.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
