ABSTRACT:
Provided is a method of monitoring a device to ascertain leakage of the gas there from. An area in the vicinity of the gas is illuminated with ultraviolet light, thereby causing the gas or its residue to fluoresce. A gas sensor is exposed to the gas whereby it generates the gas detection input signal, which is then processed to produce at least one output signal in response thereto.
