Combustible. May ignite spontaneously on contact with air. Finely dispersed particles form explosive mixtures in air.
NO open flames, NO sparks and NO smoking. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.
Use dry powder, dry sand, special powder. NO carbon dioxide, foam, water. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.
PREVENT DISPERSION OF DUST!
Avoid inhalation of dust.
Fresh air, rest.
Remove contaminated clothes. 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.
CLASSIFICATION & LABELLING
Remove all ignition sources. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Cover the spilled material with dry inert absorbent. Vacuum spilled material with specialist equipment. Then store and dispose of according to local regulations.
According to UN GHS Criteria
