TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible.  If powder: NO open flames, NO sparks, and NO smoking.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.   
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough. Shortness of breath. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety spectacles 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 Nausea. Vomiting.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Remove all ignition sources. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

EMERGENCY RESPONSE SAFE STORAGE
  Separated from food and feedstuffs, strong oxidants, strong acids and incompatible materials. See Chemical Dangers. Well closed. 

IMPORTANT DATA
Physical State; Appearance
SILVER-WHITE METAL OR BLACK POWDER. 

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

Chemical dangers
Reacts with strong acids, strong oxidants and sulfur. This generates fire and explosion hazard. 

Occupational exposure limits
TLV: 0.1mg/m³ as TWA; (ACGIH 2000). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and 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 is irritating to the eyes and respiratory tract. 

Effects of long-term or repeated exposure
The substance may have effects on the kidneys. This may result in kidney impairment.
