EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol. Effects of short-term exposure Inhalation of high concentrations of dust may cause irritation of the eyes and respiratory tract.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. Effects of long-term or repeated exposure The substance may have effects on the central nervous system.
