Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces toxic and irritating fumes including hydrogen chloride. Reacts with strong oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (not established):. 

Routes of exposure
The substance can be absorbed into the body through the skin and by ingestion. 

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed. 

Effects of short-term exposure
The substance may cause effects on the nervous system and optic nerve. This may result in cardiac disorders, respiratory failure and blindness. The effects may be delayed up to 48 hours. Medical observation is indicated. 

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 nervous system and optic nerve. This may result in tissue lesions and blindness. May cause toxicity to human reproduction or development.
