  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable.  Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion on contact with acids, alcohol, oxidizing agents or water.  NO contact with acids, alcohol, oxidizing agents or water.  Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.  Use dry sand, special powder. NO water. NO carbon dioxide, foam.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes   Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
SILVERY-WHITE-TO-GREY POWDER. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Reacts with water and alcohols. Reacts violently with oxidants, strong acids, strong bases and chlorinated hydrocarbons. This generates fire and explosion hazard.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
 

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

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of dust particles may cause effects on the lungs. The substance may have effects on the nervous system. This may result in impaired functions. 


Occupational exposure limits
TLV: 1 mg/m3, - ppm, as TWA; A4 (not classifiable as a human carcinogen).
