|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.|
|Eyes||Redness. Pain.||Wear safety goggles.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Burning sensation in the mouth.||Do not eat, drink, or smoke during work.||Rinse mouth.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Remove all ignition sources. Consult an expert! Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered dry containers. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT wash away into sewer.||
