    OK, there was mention of the street mains. Maybe he meant that the hookup lines for gas are now being done with that orange plastic, which obviously is not a ground, and the change would have un-grounded the facility pipes. That would make sense, and fits what you said. That would be if your lines are like that. Not all are (yet). If they are still steel, they would be grounded, albeit not very well, simply by being in the dirt.

    A "proper ground" can have up to 25 ohms resistance (or whatever two rods give), which is only a little under a 5A current at 120V, not near enough to pop a breaker.

    reggie_obe I already read that! I'm a bit uncertain how well grounded my panel is, unlike another property that actually has stakes into the slab. But happily, it sounds like the the risk is greatest in gas lines in the attic, and both of mine are well below that.

    Edit: so apparently the steel gas distribution system needs to be bonded, not the stainless flex (AKA CSST, Corrugated Stainless Steel Tubing). Seems an issue because street mains are now PE and not providing a ground.

    (B) Not Permitted for Use as Grounding Electrodes.
    The following systems and materials shall not be used as
    grounding electrodes:
    (1) Metal underground gas piping systems

    There IS a requirement IF the gas piping is likely to become energized, that it be "bonded to" a legitimate grounding electrode. That is a slight but important difference from being THE actual PE, and seems to allow bonding the internal piping, with no requirement for pipes outside.

    (B) Other Metal Piping. If installed in, or attached to, a
    building or structure, a metal piping system(s), including
    gas piping, that is likely to become energized shall be
    bonded to any· of the following:
    (1) Equipment grounding conductor for the circuit that is
    likely to energize the piping system
    (2) Serviceequipinent enclosure
    (3) Grounded conductor at the service
    (4) Grounding electrode conductor, if of sufficient size
    (5) One or more grounding electrodes used

    Well, it's over, and not anything like I feared. But it's good to fear sometimes and rethink your sh*t. I think the rarely used flammables will stay in the well ventilated garage, and some not touched in decades like the gallon of linseed oil need to go. I put a couple dozen decades untouched rattle cans in a bag and that will go to the waste disposal plant.

    Dude was nice, admired the shop and said he used to be an automotive machinist. Was interested in the boiler, electric panels, hallways, fire escape and roof. At the end I kinda pumped him what red flags he looks for, and the non-obvious one was yellow jacketed flex gas line. He said they're not properly grounded and lightning strikes have lit places up! Good thing he didn't see the gas riser repair done years ago with the yellow flex line. I gotta look into that.
    Glad you passed, Good for you.

    I always buy the "old guy" at the bar a shot,
    just because he is there. Keeps me on the
    good side of the local gentry.

    I like my bourbon too much to consider the investment grade stuff! There's some quite good bottles to be had for under $50, some of them wheaters like Pappy. Even Rebel Yell is a wheater. My current 'top shelf bottle' is a Woodford Reserve Double Oaked. Fantastic stuff and only like $40. We visited the distillery last year on a 'bourbon and BBQ' tour of Kentucky.

    Some years back a (very good) friend gave me a bottle of Pappy van Winkle bourbon. I've never had anything like it. Not in my budget, though, it was around $120 fifteen years ago.

    Pass on the hookers but I'll tip some Old Crow in your honor later. You'd have to have really blown my mind to get the good stuff!

    Without getting all political, this is exactly what's playing out now in the 'mask wars' across this country. One person's common sense is another's 'loss of freedom'.

    In my interpretation of that, he's telling me to live by my own code that I cited above, 'don't be idiot, don't be an asshole'. If I'm going to break the rules, do it smart and as safe as possible. Fair enough IMO. I did not interpret that as 'shut down your shop'.
