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. Prevent build-up of electrostatic charges (e.g., by grounding).   
 
EXPOSURE      
Inhalation Cough.  Avoid inhalation of dust.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. 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.   

SPILLAGE DISPOSAL
PACKAGING & LABELLING

UN Classification
 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
NFPA Code: H0; F2; R0.  Separated from strong oxidants and strong acids. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-WHITE SOLID IN VARIOUS FORMS. 

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

Chemical dangers
Decomposes on heating and on burning. This produces toxic fumes. Reacts with oxidants and strong acids. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
