TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable.  NO contact with acids, alcohol, oxidizing agents or water.  Use dry sand, special powder. NO water. NO carbon dioxide, foam. 
EXPLOSION Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion on contact with acids, alcohol, oxidizing agents or water.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.   
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
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
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered dry containers.

IMPORTANT DATA
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. 

Occupational exposure limits
MAK (respirable fraction): 1.5 mg/m³; Pregnancy risk group: D; (DFG 2008).
MAK (inhalable fraction): 4 mg/m³; Pregnancy risk group: D; (DFG 2008). 

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

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

Effects of short-term exposure
 

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.
