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 AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!  •INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Safety goggles or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Do not eat, drink, or smoke during work. Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention.
