Only if a leakage is confirmed. I have a good nose, regularly spot leaks
outside and report them. Most recently I smelled a leak from our local
pressure regulator station.

I once worked for a company that had a vessel containing 15 tons of
liquified natural gas, used for fueling gas turbine or gas engined
industrial compressors on test.

When it was needed, liquid was fed to a small boiler that heated it and
the chemical smell was added.

They once suffered a leak in the chemical dosing system, releasing the
undiluted chemical into the atmosphere. People from offices and housing
all around the area were phoning reports of a massive gas leak in

or too many onions ....

Not quite the same though - I have also commissioned the controls on an
odour control system at a curry factory and the smell when opening the
inspection covers on the semi-closed cycle, spraymist absorption vessel
is pretty well 100% onion.
