Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Water spray, foam, powder, carbon dioxide EXPLOSION EXPOSURE AVOID ALL CONTACT!  •INHALATION Local exhaust. Fresh air, rest.  •SKIN Protective gloves. Protective clothing. Rinse and then wash skin with water and soap.  •EYES Redness. Safety goggles. First rinse with plenty of water (remove contact lenses if easily possible).  •INGESTION Do not eat, drink, or smoke during work. Rinse mouth. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: P2 filter respirator for harmful particles. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Separated from oxidants, food and feedstuffs. Ventilation along the floor.
