Have..... many a time. Still here. Apparently you don’t have a clue about the old school leak detectors which were a simple propane bottle with a specialized adapter and hose. Still have that tool and use it from time to time.

Phosgene gas was a particularly nasty weapon used by the Germans in WW1 and has absolutely nothing to do with R-12 which, by the way, is the best and safest refrigerant ever developed.

And don’t even bother to throw that ozone layer BS at me.

Ever ask yourself why the propane leak detection system is old school? Here’s why: “Halide Leak Detector A halide leak detector typically uses acetylene or propane gas. After ignition, the flame from this gas heats a copper disc. Attached to this bottle of gas is a hose that is used as a sniffer to check for leaks. As the hose is moved, air is drawn through it and into the burner of the detector. When a leak is detected, the flame will change to a greenish color. A halide leak detector is dangerous to use in confined spaces or flammable areas. Never use a halide device to check a system that contains a highly flammable refrigerant because an explosion could occur. Certain refrigerants will break down when exposed to the flame and cause phosgene gas, which is poisonous.”

You apparently haven’t blown yourself up yet but I do detect some possible nerve damage.
