|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Highly flammable.||NO open flames, NO sparks and NO smoking.||Use foam, powder, carbon dioxide.|
|EXPLOSION||Vapour/air mixtures are explosive.||Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.||In case of fire: keep drums, etc., cool by spraying with water.|
|Inhalation||Cough. Sore throat.||Use ventilation, 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 spectacles.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Burning sensation.||Do not eat, drink, or smoke during work.||Rinse mouth. Rest.|
|PACKAGING & LABELLING|
|Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment.
