|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Combustible.||NO open flames.||Use water spray, powder, foam, carbon dioxide.|
|EXPLOSION||Above 80°C explosive vapour/air mixtures may be formed. 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!|
|Inhalation||Headache. Weakness. Nausea. Vomiting. Sweating. Confusion. Jaundice. Dark urine.||Use ventilation (not if powder), local exhaust or breathing protection.||Fresh air, rest. Refer for medical attention.|
|Skin||MAY BE ABSORBED! Further see Inhalation.||Protective gloves.||Rinse skin with plenty of water or shower.|
|Eyes||Wear safety spectacles.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Abdominal pain. Diarrhoea. Convulsions. Unconsciousness. Further see Inhalation.||Do not eat, drink, or smoke during work. Wash hands before eating.||Rest. Refer for medical attention .|
