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.
Fresh air, rest.
Rinse and then wash skin with water and soap.
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.
