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 when dispersed.
Effects of Short-Term Exposure:
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the
lungs
, resulting in talc pneumoconiosis.
