|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Combustible under specific conditions. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames.||Use water spray, powder, alcohol-resistant foam, carbon dioxide.|
|EXPLOSION||Risk of fire and explosion if formulations contain flammable/explosive solvents.|
|EXPOSURE||PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!|
|Inhalation||Dizziness. Sweating. Laboured breathing. Unconciousness. Weakness. Pupillary constriction, muscle cramp, excessive salivation. See Ingestion.||Use ventilation (not if powder), local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Refer for medical attention. See Notes.|
|Skin||MAY BE ABSORBED! Further see Inhalation.||Protective gloves. Protective clothing.||Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . See Notes.|
|Eyes||Redness. Pain. Blurred vision.||Wear face shield or eye protection in combination with breathing protection if powder.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Abdominal cramps. Convulsions. Diarrhoea. Nausea. Vomiting. Muscle twitching. Further see Inhalation.||Do not eat, drink, or smoke during work. Wash hands before eating.||Rinse mouth. Give a slurry of activated charcoal in water to drink. Rest. Refer for medical attention .|
