|OCCUPATIONAL EXPOSURE LIMITS
|TLV: 0.3 ppm as STEL
|The substance is very toxic to aquatic organisms.
|The occupational exposure limit value should not be exceeded during any part of the working exposure.
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 spray, by a doctor or a person authorized by him/her, should be considered.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
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.
