Combustible. Finely dispersed particles form explosive mixtures in air.
NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.
Use water spray, foam, powder, carbon dioxide.
PREVENT DISPERSION OF DUST!
Cough. Sore throat.
Use local exhaust or breathing protection.
Fresh air, rest.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
Wear safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink.
