Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Above 67°C explosive vapour/air mixtures may be formed. Above 67°C use a closed system, ventilation. EXPOSURE STRICT HYGIENE! PREVENT GENERATION OF MISTS! PREVENT DISPERSION OF DUST!  •INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Pain. Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •EYES Redness. Pain. Severe deep burns. 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 Abdominal pain. Burning sensation. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: A/P2 filter respirator for organic vapour and harmful dust.) Separated from strong oxidants, strong acids.
