EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by ingestion, through the skin and by inhalation of its aerosol. Effects of short-term exposure The substance may cause effects on the blood. This may result in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. Effects of long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization.
