Routes of Exposure:
The substance can be absorbed into the body
by inhalation,
through the skin
and
by ingestion.
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
is irritating to
the eyes
and
the respiratory tract
.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the testes.
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
