  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion. Explosive.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT expose to friction or shock.  In case of fire in the surroundings, use appropriate extinguishing media.  Combat fire from a sheltered position. 

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation See Ingestion.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. 
Skin MAY BE ABSORBED! Redness.  Protective gloves. Protective clothing.  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 Confusion. Drowsiness. Convulsions. Unconsciousness.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS CRYSTALS. 

Physical dangers
As a result of flow, agitation, etc., electrostatic charges can be generated. Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Heating may cause violent combustion or explosion. May decompose explosively on shock, friction or concussion. Decomposes on heating. This produces toxic gases including nitrogen oxides. Reacts violently with acids and bases.
