EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and through the skin. Effects of short-term exposure The substance is severely irritating to the eyes, skin and respiratory tract. The substance may cause effects on the skin. This may result in depigmentation.	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 Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the liver, spleen, thyroid and nervous system. This may result in impaired functions.
