|
Routes of Exposure:
The substance can be absorbed into the body in hazardous amounts
by inhalation,
through the skin
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air will be reached slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.
Effects of Short-Term Exposure:
Exposure at high levels could cause lowering of consciousness.
Exposure at high levels may result in the formation of methaemoglobin.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the
blood
, resulting in
anaemia
.
The substance may have effects on the
kidneys
and
liver
.
This substance is possibly carcinogenic to humans.
