IMPORTANT DATA

Physical State; Appearance
WHITE TO REDDISH FLAKES, WITH CHARACTERISTIC ODOUR. TURNS RED ON EXPOSURE TO AIR.

Chemical dangers
The substance decomposes on burning producing toxic and corrosive fumes.

Occupational exposure limits
TLV: A1 (ACGIH 2003).
MAK: Carcinogen category: 1; H; (DFG 2002).

Routes of exposure
The substance can be absorbed into the body by inhalation and 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, resulting in the formation of methaemoglobin. The substance may cause effects on the bladder, resulting in inflammation and blood in 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.
