|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
and
through the skin.
Inhalation Risk:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
irritates
the eyes
and
the respiratory tract.
The substance may cause effects on the kidneys and central nervous system
, resulting in renal failure and brain injury.
Exposure could cause lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the central nervous system
, resulting in abnormal eye movements (nystagmus).
