If your house was so full of gas that a doorbell would set off an explosion, I doubt you’d have been conscious enough to answer a knock at the door.
OT, six of the most beautiful Canadian geese just landed outside my window. I’d say that’s a nice start for the week.
Not true. The lower explosive limit for natural gas (methane) is only 5.1% at ~68 degrees, a common thermostat setting. Methane is NON-toxic at those levels and that is also nowhere near a suffocating % of the atmosphere.
Natural gas is tainted with a mercaptan (the sulfur/skunk/cabbage smell) so you can detect a gas leak, AND CALL THE GAS COMPANY.
The trouble is the mercaptan tends to populate the smell receptors in your nose, and after a while, you can’t tell the leak has gotten worse/ more concentrated.
Without being an alarmist, when you smell gas (the mercaptan) CALL THE GAS COMPANY. They really don’t mind.
