|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Combustible. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames.||Use water spray, foam, powder, carbon dioxide.|
|EXPLOSION||Finely dispersed particles form explosive mixtures in air.||Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.||In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.|
|EXPOSURE||PREVENT DISPERSION OF DUST! STRICT HYGIENE!||IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Burning sensation. Headache. Blue lips, fingernails and skin. Weakness. Dizziness. Laboured breathing. Nausea. Drowsiness.||Use local exhaust or breathing protection.||Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.|
|Skin||MAY BE ABSORBED! Further see Inhalation.||Protective gloves. Protective clothing.||Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .|
|Eyes||Redness. Pain.||Wear face shield or eye protection in combination with breathing protection.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||See Inhalation.||Do not eat, drink, or smoke during work. Wash hands before eating.||Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give a slurry of activated charcoal in water to drink. Refer for medical attention .|
