|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 AFFF, alcohol-resistant foam, powder, carbon dioxide.|
|EXPLOSION||Above 77°C explosive vapour/air mixtures may be formed.||Above 77°C use a closed system and ventilation.||In case of fire: keep drums, etc., cool by spraying with water.|
|EXPOSURE||AVOID ALL CONTACT!|
|Inhalation||Cough. Burning sensation. Shortness of breath. Laboured breathing.||Use ventilation (not if powder), local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Refer for medical attention.|
|Skin||Redness. Skin burns. Pain. Blisters.||Protective clothing.||First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.|
|Eyes||Redness. Pain. Loss of vision. Severe deep burns.||Wear face shield.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Abdominal cramps. Abdominal pain. Burning sensation. Weakness.||Do not eat, drink, or smoke during work. Wash hands before eating.||Rinse mouth. Rest. Refer for medical attention .|
|PACKAGING & LABELLING|

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.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
