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, foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE      
Inhalation   Use ventilation.   
Skin   Protective gloves.   
Eyes Redness. Pain.  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
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.

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic fumes including nitrogen oxides and sulfur oxides. Reacts violently with acids, bases and strong oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
 

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

Effects of short-term exposure
May cause mechanical irritation to the to the eyes. 

Effects of long-term or repeated exposure
