|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation and
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
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, kidneys and liver, when ingested.
The effects may be delayed.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
Animal tests show that this substance possibly causes toxic effects upon human reproduction.
