|OCCUPATIONAL EXPOSURE LIMITS|
|TLV: 2 ppm as TWA; 5 ppm as STEL|
|The compound decomposes in the body to hydrogen fluoride, see ICSC 0283 Hydrogen fluoride.
Depending on the degree of exposure, periodic medical examination is suggested.
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.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
