Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic fumes. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Carcinogen category: 2; (DFG 2003). 

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

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

Effects of short-term exposure
The substance may cause effects on the blood. This may result in formation of methaemoglobin. Medical observation is indicated. The effects may be delayed. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA

NOTES
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
Similar substances cause bladder tumours in humans.
