What the gently caress. Is this something randomly discovered in a regular home with an amazingly bad install of something? How would that ever happen in the first place? It surely isn't something intentionally built.

I assumed that was intentionally fabricated for some sort of test or report purpose, because I couldn't even imagine it occurring in the wild.

I'm trying to imagine how I'd phrase myself in the call to the emergency services. Electrical short circuit, glowing red hot gas line, imminent water heater explosion and death of everyone in the house shrapnel radius. Where would you even start?

I feel like I would be more looney toons style ran away zoom lines and my 911 call would involve equal parts screaming and the words minimum safe distance. I know it's "stable" in that without air it won't ignite, but so is old crystallized tnt so long as it never experiences a shock.

The third tweet down gives the picture source, it's from the homeowner before she called emergency services. ENERGIZED NEUTRAL EFFECTS ON CORRUGATED GAS SUPPLY LINES Apparently her home got the neutral energized.

That includes her first noting a "shower of sparks" raining down from her service line. Forget the main breaker, I repeat my statement about looney toons zoom lines.

You know, I'm still ok with Norway's weird "two or three live phases to the wall, no neutral, provide your own ground" system. When you know both phases are live you avoid that entire class of "but that's not supposed to happen" problems ... or at least you notice the problem early. And of course, all phases have breakers. (The downside is that there is no easy way to get 400V out of it; the highest you can cobble together is the normal 230V phase/phase. I'm not an electrician, and I don't know how they provide higher voltages to people that require them.) We also don't have piped gas, which seems sort of comforting given the only time we hear about it is when something explodes. I assume that's mostly reporting bias - nobody talks about how exciting it is that most water heaters and furnaces didn't vaporise the surrounding house(s) today.

Ok, I'm dumb. Neutral gets energized and completes the circuit with ground if you shut off the main breaker since neither of those would be protected?

Pole hot to pole neutral to you panel neutral bar to panel ground hopefully to actual ground. Due to the other stuff that has other paths to ground and the basically unlimited power all of your stuff gains potential.

Sounds like an unaffiliated party, such as a fifth grader doing a science fair project, ought to look into this.

You say that like we want/need dryers that blow air hot enough to sterilize. That wouldn't end well. Edit: Oops, wrong quote button.

If I remember right, a fifth grader who noticed a lot of complaints from her classmates about the hand dryers being painfully loud did do a study on her own to see how loud they were. Turns out, most hand dryers are well above the maximum decibel level permitted! And the companies don't test them in conditions similar to where they'll be used; they get tested in soundproof rooms.

I'm thinking about that energized gas line and it occurs to me that shutting off the main gas to the house could make the situation more dangerous. With a loss of pressure, air could enter the gas line from the end of an appliance unless there's some kind of backflow prevention? Obviously the gas, however hot, can't ignite until there's oxygen available, so keeping the line full of pure gas with no oxygen is paramount. Also, if that hot water heater's burner is on, that keeps a flow of cooler gas running through the red hot energized section of corrugated piping, which should actually cool it a little? It's one of those cases I think you'd have to study in lab conditions to be certain which action is less dangerous.

There are no real conclusion to be drawn on what the "correct" move would be in the wild. You've correctly identified that the gas, while contained in the line is way below it's UEL even though it's also way above its ignition temperature. Flowing gas may have a cooling effect, but that probably doesn't matter and you can't control if it's flowing or not with any safe and reliable means. What really matters is how long it's going to be contained. And for that, every different hose, length of hose, exact temperature, the number of times it's been bent, how much it's been bent, etc, etc, etc, etc are going to matter more than anything else. Basically un-knowable details of the particular material and its installation. So you just shut off the gas. And if possible, vent from another port or appliance. Hell, that's emergent enough to justify doing some real damage outside (cutting outside-accessible piping with something like a hydraulic tool) in order to get gas out of the lines inside.

Natural gas flow rates are Not High. The pressure required for domestic appliances is measured in fractions of a PSI.
