  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.    NO open flames.    Use powder, water spray, foam, carbon dioxide.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation   Avoid inhalation of dust.  Fresh air, rest. 
Skin Severe itching. Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention if skin irritation occurs.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
YELLOW CRYSTALS. TURNS DARK GREEN ON EXPOSURE TO LIGHT. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating and on contact with strong acids. This produces toxic and irritating fumes including nitrogen oxides and sulfur oxides. Reacts violently with strong oxidants. This generates fire hazard.
