Caster locks are to keep poo poo from rolling away on level ground. That should have been strapped.

armchairyoda posted:Lol, let me tell you some stories of farmers just “digging for new fence posts”... Couple of years back I got a call on our Highways customer line and when I picked it up could barely hear the caller over an awful howling noise. I could tell she was incandescent about a gas line but the details were getting lost so eventually I managed to work out where she was calling from and sent a supervisor out to find out what the gently caress. When he got out there she was an elderly farmer out in the sticks without a main gasline so she had a tank on site with a connecting port out on the borderline of our verge and her property. One of our dipshit contractors who do the rural verges had mowed right over the capped connection with one of these and the howling sound was gas erupting from the site under pressure:  The gas company ended recapping it quickly and our contractor had to pay out, but I had a sketchy hour or so hoping one of our teams hadn't just turned half a mile of countryside into a bombsite.

Jet Jaguar posted:We had to have our sewer line replaced and at one point they had five guys just standing around, staring into one of the trenches. "Well this can't be good," I said. I still remember the morning they went to dig up the street next to the shop where I worked at the time and with literally the first touch of the drill they hit a gas main. It was fun watching the realisation of the scale of the fuckup develop - we wisely self-evacuated to the next corner as soon as we saw the mirage of what was obviously a *lot* of gas escaping from the small hole in the street, and watched as a confab of police, fire brigade and blokes in all the colours of the high-viz rainbow came to stare at the little hole and shrug (for added fun the street was right next to the police station) before the police moved us back to the next corner, evacuating all of the other shops as they went. Then the only panicked-looking fireman I've ever seen came running down the street shouting MOVE BACK NOW! and we were evacuated a full 500 metres away (coincidentally to right outside a pub where we spent the rest of the day fielding calls from the owner of the shop asking us why we couldn't sneak back through the cordon to grab stuff to sell). Anyway it turns out that they'd hit an undocumented, blocked-off spur of the 3-foot high-pressure main that supplied a big chunk of gas to West London, and the company that were just supposed to be fixing a damaged drain *had* done a survey of where they were supposed to be digging, on the other side of the street, but the crew had gone to the wrong side of the street, seen that there were no marks indicating they couldn't drill, and, welp. e: While trying to find some news reports about it (probably a fool's errand as it happened in the mid-90s so as far as the internet's concerned might as well have been in the Byzantine Empire) I did come across this: quote:The defendants were found to be joint tort feasors in Brooke v.

I have always thought piped gas sounds like a safety hazard right out of dystopian steampunk. I don't know if that's the selection bias from only hearing about it when it goes wrong, or if you all are just too familiar with it to notice.

My parents' neighbor a Comcast contractor come out to do some trenching work when I was a kid and they managed to hit the main gas main supplying the neighborhood -- made obvious by a deafening roaring sound you could hear well up the street and chunks of earth pushed up in several neighbors' yards across the street as the gas worked its way out of ground. The contractors were standing around looking confused, some were smoking, so after 20 or so minutes of inaction I called the fire department. Very quickly thereafter the whole block was evacuated and someone got the gas company out to shut off the main and work the repair. Interestingly, the gas company folks weren't concerned about anyone or anything until after the shutoff -- something to do with the fuel-air mixture I suppose. To this day I'm not sure what size line they hit but it must have been a doozy.

"The gas line going into my house is working like it's supposed to. None of my poo poo has exploded or caught fire, and my family is healthy and safe." Is not a story anyone, even me, gives a poo poo about. Food for thought; Touching the gas with your bare hands won't instantly kill you. The same cannot be said for the electricity being piped into your home.

On one hand, true. On the other hand, a slow electricity leak into my basement doesn't turn my house into a bomb, and accidentally digging into electrical mains does not carry an overhanging risk of levelling the entire city block. (Also, brushing your hand over 230V may be both risky and unpleasant, but I've done it enough times to confirm that it won't instagib you either.)

There are exceptions to this. there are some buried high voltage cables where if you puncture the containment, you let out the dielectric cooling oil, and you're going to have a very bad day.

That's fair. Punching through something like a long distance HVDC cable would be better experienced as a youtube documentary a year or two after the crater calms down. I'm just saying that if we had never had piped gas outside industrial settings before, we would have looked at it with some distrust if it were suggested today.

Gas stations are kind of nuts, yeah - let's just keep huge tanks of volatile and highly flammable chemicals around and let random members of the public come and pump as much as they want/can afford. Not really a huge source of major accidents, somehow.

Not really a huge source of major accidents, somehow. If gasoline/diesel wasn't the literal backbone of the world economy, there is no way that it would be approved for use by the public with how carcinogenic and straight up unsafe it is. It's only via collective societal experience and normalization that we (generally) safely handle it so much at all.

Which is also the point I was trying to make about piped gas - except that it has not really been a thing here, so I never got used to the idea in the first place.

Not really a huge source of major accidents, somehow. Volatile, flammable and corrosive. If the stuff hadn't basically been grandfathered into our society pre-OSHA you'd need hazmat training just to pump gasoline and diesel into your car.
