TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF (PREGNANT) WOMEN!   
Inhalation   Use local exhaust or breathing protection.  Refer for medical attention. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes   Wear face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

IMPORTANT DATA
Physical State; Appearance
WHITE-TO-PALE-GREEN CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces toxic and irritating fumes including nitrogen oxides and sulfur oxides. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Carcinogen category: 3B; (DFG 2004). 

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

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

Effects of short-term exposure
 

Effects of long-term or repeated exposure
The substance may have effects on the thyroid and liver. This may result in impaired functions. Animal tests show that this substance possibly causes malformations in human babies.
