Gives off irritating or toxic fumes (or gases) in a fire. Heating will cause rise in pressure with risk of bursting. NO open flames. Powder, alcohol-resistant foam, water spray, carbon dioxide. Explosion In case of fire: keep drums, etc., cool by spraying with water. Exposure PREVENT DISPERSION OF DUST! PREVENT GENERATION OF MISTS!  •Inhalation Blue skin. Blue lips or finger nails. Dizziness. Headache. Nausea. Shortness of breath. Confusion. Convulsions. Unconsciousness. Local exhaust or breathing protection. Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.  •Skin MAY BE ABSORBED! (Further see Inhalation). Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •Eyes Redness. Pain. Safety goggles , or face shield . First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •Ingestion Abdominal pain. (Further see Inhalation). Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Give plenty of water to drink. Refer for medical attention. Spillage Disposal Storage Packaging & Labelling Remove all ignition sources. Do NOT wash away into sewer. Sweep spilled substance into containers. Collect leaking liquid in sealable containers.
