    Sad. Wonder if it was something in the house or a main.

    I wonder if plastic gas lines are as safe as steel gas lines. They seem to be prolific in my neck of the woods.

    Plastic gas lines?

    It seems I have heard of far more csst incidents than from polyethylene distribution.

    Locally, we had a house lifted off it's foundation when an HVAC tech lit his acetylene torch in its crawlspace last week. There was a natural gas leak repair where the polyethylene connected with the main a couple weeks earlier. According to the local news, the torch kit involved was missing. The gas company says without being able to inspect the missing torch kit, they won't assume responsibility. The tech was injured. I have to find that story.

    Here it is...My memory of details isn't great

    This was in a rowhouse neighborhood that is said to have been built around 1960. It's a few miles from my house.

    As of now, search-and-rescue teams are still working. It'll be a while before we know what went wrong.

    The missing torch would get the gas company off from responsibility.....perhaps...????

    If that was an acetylene explosion wouldn't the tech be more than just injured?

    The article doesnt discuss extent of injuries but I have a hard time believing a leaky torch could lift a house "6 inches" into the air. He didnt look very hurt running away in video.

    Acetylene has a little more kick than NG.

    Actually, it has a lot more kick.

    Aside from that I have no idea.

    Latest news reports confirm the gas mains in that neighborhood were installed in the 1960s . So they are probably not the original cast-iron with doubled lead-and-oakum joints.

    I'm guessing that whatever went wrong, happened inside one of the houses.

    If it is 1960's the services are still black iron that has been buried for 60 or so years, but plenty of other things that could have gone wrong as well.
