|FIRE & EXPLOSION||Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire. Vapour/air mixtures are explosive.||NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.||NO water. Use AFFF, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.|
|STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!|
|SYMPTOMS||ACUTE HAZARDS||FIRST AID|
|Inhalation||Cough. Sore throat. Burning sensation. Laboured breathing. Shortness of breath. Symptoms may be delayed. See Notes.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. See Notes.|
|Skin||Redness. Pain. Blisters. Skin burns.||Protective gloves. Protective clothing.||Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .|

|Reacts violently with fire extinguishing agents such as water.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
