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. Prevent build-up of electrostatic charges (e.g., by grounding).
Use water spray, powder, foam, carbon dioxide.
Fresh air, rest.
Wear safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
