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, especially if powdered.
Effects of Short-Term Exposure:
The substance may cause effects on the
blood
, resulting in
the formation of methaemoglobin.
Medical observation is indicated.
The effects may be delayed.
Effects of Long-Term or Repeated Exposure:
|
|
Physical
Properties
|
