Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic and corrosive fumes including nitrogen oxides. Reacts with strong acids, strong bases and strong oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly. 

Effects of short-term exposure
The substance is mildly irritating to the eyes and skin. Ingestion could cause effects on the blood. This may result in formation of methaemoglobin. 

Effects of long-term or repeated exposure
