NO open flames. Water spray, foam, powder, carbon dioxide. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. EXPOSURE  •INHALATION Ventilation. Fresh air, rest.  •SKIN Protective gloves. Rinse and then wash skin with water and soap.  •EYES Redness. Safety spectacles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. Rinse mouth. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: P2 filter respirator for harmful particles. Do NOT let this chemical enter the environment. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Store in an area without drain or sewer access.
