|EC Number: 231-104-6
|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire. May ignite spontaneously on contact with air. Finely dispersed particles form explosive mixtures in air.||NO open flames, NO sparks and NO smoking. NO contact with moisture or any other substances. PREVENT DISPERSION OF DUST. Closed system, dust explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding).||Use dry sand, special powder. NO water. NO other agents. See Notes.|
|Inhalation||Cough. Sore throat. Shortness of breath.||Use local exhaust or breathing protection.||Fresh air, rest.|
|Skin||Redness.||Protective gloves.||Remove contaminated clothes. Rinse skin with plenty of water or shower.|
