Delta Echo posted:Compared to the author using the wrong shoes or shuffling their feet, no. The scenario I imagine is novice runner wearing Pumas at 24 hour fitness. You know, the casual line of Pumas. It depends on the treadmill but you'd be lucky to get two years out of one at a reasonably popular gym before the brushes need replacing. My dad runs a fitness equipment repair business and a lot of his calls are about either treadmill belts or the antistatic brushes. There was an office that bought a mid-range treadmill designed for home use and they blew though the brushes in less than six months. I can totally believe that a poorly maintained gym at a military facility has treadmills that are all worn out. The solution? If no one's going to actually fix it, us an antistatic wristband to the metal hand rails. There's also an antistatic spray you can use on the belt but it's not very effective.

The arm of that excavator is hyper extended backward, and when it was traveling it was leaning almost horizontally forward. It didn't cut through the overpass as much as it poked through it.

Pretty old, thread regular. Never did find out what was in that container, though.

I worked at a steel mill during college in a continuous caster. It's a like 5 story building were the pour steel down some things that might can be likened to waterslides. My office was on the top floor, because thats the only place the offices for the caster were at. It was rad to come in at 7am while they were pouring a ladle or getting the ladle in position because the glow on ~3000F molten steel is something that you can only see in certain places. Anyway, the ladle is the thing from that gif. Brought back memories.

A steel plant in Hamilton had all their pipes insulated at the ceiling and clad with aluminum jacketing. One observant engineer noted the melting point of aluminum and what the temps were of pouring liquid steel directly below them. Basically, if there was ever an incident, it would rain liquid aluminium balls from the ceiling as the cladding melts off. They paid a company to come in and switch that out for galvanized steel.

So what exactly happened there? I'm guessing there was a tiny drop of water in the mold and it caused a miniature steam explosion?

They may grab a magnet for the crane and clean up the scrap that got blown out and may interfere with them running again but usually things keep rolling right along. The longer that furnace sits, the colder it gets and the more electric and money its gonna take to get it up over 3000F. gently caress me. Industry is loving crazy. Let's leave this to robots and all get white collar jobs.

KoRMaK posted:I heard a story about a guy who fell into the ladel as it was being poured. He would have floated on top of the much, much more dense molten metal. This is also what happens when you fall onto molten lava: you sink into it like an inch or two at most, because humans are only a little more dense than water, and molten lava (or steel) is a hell of a lot more dense than that. I mean, I'm sure he died very quickly and burned like a fireball as all his bodily water steamed off and his body fat flashed to vapor etc. etc, it would not have been pretty if you could see through all the smoke, but I expect most of him could have been just scraped off the surface of the metal the same way you'd scrape off slag.

You can also do this with mercury without instantly bursting into flames and dying (you'll die later on from heavy metal poisoning).

Maybe it was just designed to random try and burn down large parts of what ever steel work it was installed. If so it was working perfectly!
