PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Water spray, powder.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE
AVOID ALL CONTACT!

•INHALATION
Ventilation (not if powder), local exhaust, or breathing protection.
Fresh air, rest.
•SKIN Redness.
Protective gloves. Protective clothing.
