Understanding Halide Leak Detectors

Explanation:

The statement is false. The halide leak detector is used to detect the presence of halogens, such as chlorine, bromine, or iodine, in a gas or liquid. It works by producing a blue or green flame when it comes into contact with halides. Phosgene gas, on the other hand, does not contain any halogens, so it would not produce a blue or green flame with a halide leak detector.

Therefore, it is important to note that the resulting blue or green flame from a halide leak detector does not indicate the presence of phosgene gas. It is crucial to use the detector in well-ventilated areas for safety measures, but not specifically to detect phosgene gas.
