LOL! I'm very paranoid about gas leaks, mostly because of having lived in New York for many years, where gas leaks abound. With faulty gas plumbing done by fly-by-night unlicensed handymen or supers, careless construction or demolition and old pipes (not to mention poorly capped gas lighting fixtures left in old apartments), it's a wonder there aren't more explosions.
There was a catastrophic collapse of most of one side of a housing project high-rise in London due to a fly-by-night installation of a gas stove . . . guy cracked the fitting by overtightening. Lady got up one morning, turned on the stove, and POW.
Ronan Point disaster report. The collapse was exacerbated by poor design and construction of "prefab" units - there was no support redundancy, and necessary linkage hardware was not installed or installed improperly, and lazy contractors left voids filled with rubbish instead of the required rebar and cement.
