EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion. Effects of short-term exposure The substance is irritating to the skin and eyes. Ingestion could cause effects on the blood. This may result in the formation of methaemoglobin. Medical observation is indicated. The effects may be delayed.	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.
