|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Combustible.||NO open flames.||Use water spray, powder, foam, carbon dioxide.|
|EXPLOSION||Finely dispersed particles form explosive mixtures in air.||Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.|
|EXPOSURE||PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!|
|Inhalation||Cough. Laboured breathing.||Use local exhaust or breathing protection.||Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.|
|Skin||Redness.||Protective gloves. Protective clothing.||Remove contaminated clothes. Rinse and then wash skin with water and soap.|
|Eyes||Redness. Pain. Blurred vision.||Wear safety goggles.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Dizziness. Headache. Nausea. Shortness of breath. Convulsions. Vomiting. Ringing in the ears.||Do not eat, drink, or smoke during work. Wash hands before eating.||Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .|
