Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Finely dispersed particles form explosive mixtures in air. EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Shortness of breath. Sore throat. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Protective gloves. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Safety goggles, 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 take to a doctor.  •INGESTION Diarrhoea. Nausea. Vomiting. Do not eat, drink, or smoke during work. Rinse mouth. Give one or two glasses of water to drink. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: P1 filter respirator for inert particles. Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting.
