    Huh, steam burns from a boiler releasing all of its 180 degree water, got it! CBS news has really taken a turn for the worse for some reason!

    it wasn't 180, something happened causing the controls to runaway or it was actually a steam system, the water was superheated, when it returned to atmospheric pressure it flashed to steam and it likely had a faulty or missing relief valve(although under some circumstances just the relief valve opening could be pretty violent).

    they barely have the resources to report the story much less research the intricacies of boiler accidents. the only part i fault them for is that instead of saying nothing they used some sort of "ai" tool that gave them fictional information.

    at some point there will be an engineering report on what happened.

    hopefully it isn't like the repot on the block that blew up in flint that was essentially you aren't important enough to bring in the right experts to figure out exactly what gas thing failed.

    Later reports say it was a large hot water holding tank, not a boiler, that ruptured. From the extensive damage it does look like an overpressure event.

    Oddly, Googling "Maryland boiler explosion" also got me the link below to an actual boiler "explosion" that happened last fall in a Baltimore police station. It looks like the front of the boiler got blown off, maybe from gas leak/delayed ignition.

    Relief or safety valve rusted closed and or plugged with a pipe plug+ some control ran away.
