Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces nitrogen oxides. Reacts with strong oxidants. Attacks some forms of plastic and rubber. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes. The substance may cause effects on the liver. This may result in liver impairment. 

Effects of long-term or repeated exposure
