EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
The substance and the aerosol are irritating to the eyes and respiratory tract. The substance may cause effects on the central nervous system, digestive tract and circulatory system. This may result in severe haemorrhage, loss of fluids and electrolytes, collapse, shock and death. Exposure far above the OEL could cause death. 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 with skin may cause dermatitis. The substance may have effects on the peripheral nervous system, skin, mucous membranes and liver. This may result in neuropathy, pigmentation disorders, perforation of the nasal septum and cirrhosis. This substance is carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
