Physical State; Appearance
WHITE POWDER. 

Physical dangers
No data. 

Chemical dangers
No data. 

Occupational exposure limits
 

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. 

Effects of short-term exposure
Inhalation of high concentrations of dust may cause irritation of the eyes and respiratory tract. 

Effects of long-term or repeated exposure
The substance may have effects on the central nervous system.
