WHITE-TO-REDDISH FLAKES WITH CHARACTERISTIC ODOUR. TURNS RED ON EXPOSURE TO AIR. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic and corrosive fumes. 

Occupational exposure limits
TLV: A1 (confirmed human carcinogen); (ACGIH 2003).
MAK: Carcinogen category: 1; Skin absorption (H); (DFG 2002). 

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

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

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

Effects of long-term or repeated exposure
This substance is carcinogenic to humans.
