Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic fumes of of nitrogen oxides. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Carcinogen category: 2; Skin absorption (H); Sensitization of skin (SH); (DFG 2005). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol or vapour, 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, skin and respiratory tract. The hot liquid may cause severe skin burns. The substance may cause effects on the liver and blood. This may result in liver damage and formation of methaemoglobin. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. This substance is possibly carcinogenic to humans. May cause genetic damage in humans.
