|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Combustible. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames.||Use powder, AFFF, foam, carbon dioxide.|
|EXPLOSION||Above 74°C explosive vapour/air mixtures may be formed.||Above 74°C use a closed system and ventilation.||In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. Combat fire from a sheltered position.|
|EXPOSURE||AVOID ALL CONTACT!||IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Convulsions. Cough. Dizziness. Headache. Laboured breathing. Nausea. Shortness of breath. Unconciousness. Vomiting. Irregular heartbeat. Chest tightness.||Use closed system or ventilation.||Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.|
|Skin||MAY BE ABSORBED! Redness. Pain. See Inhalation.||Protective gloves. Protective clothing.||Rinse and then wash skin with water and soap. Refer for medical attention .|
|Eyes||Redness. Pain.||Wear face shield 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||Abdominal cramps. Burning sensation. Convulsions. Unconsciousness. See Notes. See Inhalation.||Do not eat, drink, or smoke during work.||Rinse mouth. Refer for medical attention .|
