NO open flames. Water in large amounts, water spray, foam. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE!  •INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Redness. Pain. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Blurred vision. Safety spectacles, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Burning sensation. Do not eat, drink, or smoke during work. Rinse mouth. Give plenty of water to drink. Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. (Extra personal protection: P2 filter respirator for harmful particles). Well closed.
