Physical dangers
 

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

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
The substance may have effects on the liver. This may result in liver impairment.
