  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Finely dispersed particles form explosive mixtures in air.  NO open flames.  Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.  Use water spray, powder, foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety spectacles, face shield or eye protection in combination with breathing protection if powder.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain.  Do not eat, drink, or smoke during work.  Rinse mouth. Rest. Refer for medical attention .

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
WHITE CRYSTALS OR FLAKES. 

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

Chemical dangers
Decomposes on heating. Decomposes under the influence of strong oxidants. This produces acrid, toxic fume. 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
The substance is mildly irritating to the skin and respiratory tract. 

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 contact with skin may cause dermatitis under the influence of UV light. 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment.
