|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 by an authorized person, should be considered.
Do NOT spray water on a leaking cylinder (to prevent corrosion of the cylinder).
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
