FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use coarse water spray, 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 Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap.
