Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Water spray, foam, dry powder, carbon dioxide. EXPLOSION EXPOSURE  •INHALATION Local exhaust or breathing protection. Fresh air, rest.  •SKIN Redness. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Safety goggles. 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. Wash hands before eating. Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: P2 filter respirator for harmful particles.
