Liquid formulations containing organic solvents may be flammable. NO open flames. Powder, AFFF, foam, carbon dioxide. EXPLOSION In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Ventilation, local exhaust, or breathing protection. Fresh air, rest.  •SKIN Redness. Burning sensation. Protective gloves. 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. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Do NOT wash away into sewer. Do NOT let this chemical enter the environment. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: A/P2 filter respirator for organic vapour and harmful dust. Provision to contain effluent from fire extinguishing.
