Vintage Everyday has posted a collection of photos of railway locomotives which had suffered boiler explosions.

Fourth one from the last..... OH MY SAINTS IN HEAVEN! Shocked
Would it be too much to hope that no one was killed (or even maimed) in that?

Wow, I never knew what was inside the biolers. I guess it is like most technology and infrastructure, in that until it fails, you never think about how it works.

Explosions in spaghetti factories!

Al those steam boilers have tubes - just think of cleaning all the tubes on a destroyer or battleship!!

I fear it would be too much.

Some of those explosions would seem to have been caused by crownsheet rupture, but not all. Many seem to be the result of structural weaknesses in the boiler shell itself, or in those spectacular blowouts where the boiler tubes are blown out through the smokebox, perhaps failure of the (usually rivetted) joint between the boiler shell and the front tubeplate.

 Whatever - certainly sobering. When a locomotive type boiler ruptures, the internal pressure, anything from 100 to 300 lbs per square inch (or nowadays, the equivalent in kilopascals) instantly drops to atmospheric pressure and all the water in the boiler instantly flashes into steam; with the explosive force equivalent to a good sized bomb. The chances of survival of anyone standing close by would be close to zero, I would guess.

IIRC most of time, fatalities caused by boiler explosions were (with the possible exception of locomotive crews) caused by shrapnel, or other debris being flung out rather than the force exerted. In the case of failure at the smokebox the crews would have probably survived, as would anyone else not directly in front of the loco.

Shrapnel certainly, i.e great whirling chunks of rivetted steel plate, but also a rapidly expanding cloud of very, very hot steam. Nasty altogether.
