PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, alcohol-resistant foam, water spray, 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
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!

•INHALATION

Fresh air, rest. Refer for medical attention.
•SKIN Redness.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water.
