Not combustible. Finely dispersed particles form explosive mixtures in air.
If powder: NO open flames, NO sparks, and NO smoking. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.
In case of fire in the surroundings, use appropriate extinguishing media.
PREVENT DISPERSION OF DUST!
Cough. Shortness of breath. Sore throat.
Use local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Wear safety spectacles or eye protection in combination with breathing protection if powder.
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. Wash hands before eating.
CLASSIFICATION & LABELLING
Remove all ignition sources. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
According to UN GHS Criteria
Transportation UN Classification
