EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of long-term or repeated exposure
The substance may have effects on the liver. This may result in tissue lesions. This substance is possibly carcinogenic to humans. 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
