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 powder, alcohol-resistant foam, water spray, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   AVOID ALL CONTACT!   
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes   Wear face shield or eye protection in combination with breathing protection if powder.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: chemical protection suit including self-contained breathing apparatus. Sweep spilled substance into sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

IMPORTANT DATA
Physical State; Appearance
ODOURLESS COLOURLESS CRYSTALS. PELLETS OR WHITE GRANULAR POWDER. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating. This produces toxic fumes including nitrogen oxides. Reacts with strong oxidants, strong acids and strong bases. 

Occupational exposure limits
TLV not established.
MAK: Carcinogen category: 2; Germ cell mutagen group: 3A; Skin absorption (H); (DFG 2009). 

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

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

Effects of short-term exposure
The substance may cause effects on the nervous system. Exposure could cause lowering of consciousness. 

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