TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, powder, alcohol-resistant foam, carbon dioxide. 
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   Use ventilation.  Fresh air, rest. 
Skin Redness.  Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting.   
EC Classification
 
UN Classification
 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
  Separated from acids, strong oxidants and halogens. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-WHITE POWDER WITH CHARACTERISTIC ODOUR. 

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

Chemical dangers
Decomposes on burning. This produces toxic fumes including nitrogen oxides. The solution in water is a weak base. Reacts with acids, strong oxidants and halogens. 

Occupational exposure limits
TLV: 5mg/m³ as TWA; (ACGIH 2005). 

Routes of exposure
The substance can be absorbed into the body by ingestion. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is mildly irritating to the eyes and skin. 

Effects of long-term or repeated exposure
