Routes of Exposure:
The substance can be absorbed into the body
by inhalation
.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.
Effects of Short-Term Exposure:
Effects of Long-Term or Repeated Exposure:
Lungs may be affected by repeated or prolonged exposure to dust particles.
The substance may have effects on the
nervous system
, resulting in
impaired functions
.
