A harmful concentration of this gas in the air will be reached very quickly on loss of containment. The substance is corrosive to the eyes, the skin, the respiratory tract. Rapid evaporation of the liquid may cause frostbite. Exposure to high level may result in death. The effects may be delayed.
Medical observation is indicated.
The substance may have effects on the lungs , resulting in fibrosis, impaired functions. 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 is therefore essential. The odour warning when the exposure limit value is exceeded is insufficient. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
