IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-LIGHT-YELLOW CRYSTALS. 

Physical dangers
 

Chemical dangers
On combustion, forms toxic fumes including carbon monoxide. 

Occupational exposure limits
TLV: 5mg/m³ (ceiling value); (ACGIH 2004). 

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

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 is irritating to the eyes and respiratory tract. 

Effects of long-term or repeated exposure
