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 powder, water spray, foam, carbon dioxide. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Prevent deposition of dust. Closed system, dust explosion-proof electrical equipment and lighting.   
 
EXPOSURE      
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety spectacles.  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. Give one or two glasses of water to drink. Seek medical attention if you feel unwell. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
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. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-YELLOW FLAKES OR WHITE-TO-YELLOW CRYSTALLINE POWDER. 

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

Chemical dangers
On combustion, forms nitrogen oxides. The solution in water is a weak acid. Reacts with oxidants. This generates fire hazard. 

Occupational exposure limits
TLV not established.
MAK (not established):. 

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

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

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

Effects of long-term or repeated exposure
