In case of fire in the surroundings: use appropriate extinguishing media. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  •INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Redness. Protective gloves. Protective clothing. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Safety goggles. First rinse with plenty of water (remove contact lenses if easily possible).  •INGESTION Burning sensation. Do not eat, drink, or smoke during work. Rinse mouth. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: P3 filter respirator for toxic particles. Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting, then remove to safe place. Separated from strong reducing agents , food and feedstuffs . Do not transport with food and feedstuffs. Signal: Danger Flam circle-Health haz May intensify fire; oxidizer Causes damage to the nose through prolonged or repeated exposure if inhaled May cause cancer SEE IMPORTANT INFORMATION ON BACK ICSC: 1607 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994.
