Not combustible. Finely dispersed particles form explosive mixtures in air.
In case of fire in the surroundings, use appropriate extinguishing media.
PREVENT DISPERSION OF DUST!
Use local exhaust or breathing protection.
Fresh air, rest.
Rinse skin with plenty of water or shower.
Wear safety goggles.
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.
