  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Highly flammable when finely divided. Gives off irritating or toxic fumes (or gases) in a fire.  See Notes.  NO open flames, NO sparks and NO smoking. NO contact with water or any other substances.    Use dry sand, special powder. NO hydrous agents, carbon dioxide, other agents.   

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation See Notes.    Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion Burning sensation in the mouth and in the chest and stomach.  Do not eat, drink, or smoke during work.  Rinse mouth. Seek medical attention if you feel unwell. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Remove all ignition sources. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT wash away into sewer. Sweep spilled substance into covered dry containers. Carefully collect remainder. Then store and dispose of according to local regulations.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
SILVERY-WHITE METALLIC SOLID IN VARIOUS FORMS. 

Physical dangers
 

Chemical dangers
Reacts with water. This produces flammable/explosive gas (hydrogen - see ICSC 0001). This generates fire and explosion hazard. Contact with many other substances may cause dangerous reactions. Decomposes on heating. This produces toxic and irritating fumes.
