Physical dangers
 

Chemical dangers
 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

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
Tumours have been detected in experimental animals but may not be relevant to humans.
