|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Flammable. Gives off irritating or toxic fumes (or gases) in a fire. Above 31°C explosive vapour/air mixtures may be formed. See Notes.||NO open flames, NO sparks and NO smoking. Above 31°C use a closed system, ventilation and explosion-proof electrical equipment.||Use dry powder. Use foam. Use carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.|
|Inhalation||Dizziness. Drowsiness. Headache. Nausea. Vomiting. Weakness. Unconsciousness.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Refer for medical attention.|
|Skin||Redness. Pain.||Protective clothing. Protective gloves.||Remove contaminated clothes. Rinse and then wash skin with water and soap.|
|Eyes||Redness. Pain.||Wear safety goggles 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||Nausea. Vomiting.||Do not eat, drink, or smoke during work.||Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Rest.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
