Nemty... rare is the Egyptian god that I never ever heard before of.
Incidentally, are there Aztec gods in Danmachi?
None in Canon. Frankly speaking, I would love it if Alivaril fixed that.
That sounds like a Darwin Award candidate story.
That's like anti-safety, there's a OSHA checklist somewhere of things that should never be done, and somebody went down it in order to get to that situation.
Wouldn't surprise me if it was. And anyone can buy a powersaw. Well, maybe not children, I imagine the cashier would probably stop them and ask some pointed questions. But you get my point. You can have one set up in your home. And people will do really dumb shit when they're working in their garage/personal workshop. Professionals would probably be wearing a face mask, since sawdust is a known carcinogen. Honestly, a lot of particulates are, if they're anything that can linger in the lungs for a long period of time. But never underestimate the stupidity of amateurs.
Honestly, though, the scariest ignition source for dust explosions is probably electrostatic discharge. Mostly because so many things can build up a static charge. Notably, a poorly installed conveyor belt is indistinguishable in effect from a Van de Graff generator.
Just anything that burns exothermally will make a dust explosion. And magnesium is notorious for its flammability. Doesn't need anything special to figure this stuff out.
True. But uh...magnesium powder explosions have been tested experimentally, practically, and accidentally, unfortunately.
Flour can also cause dust explosion (although it's harder to set on fire). So don't smoke in the kitchen either. Just don't smoke, period.
Corn starch and sugar, too. And also enough pollen, apparently. I don't think the density threshold required is anywhere low near enough to happen accidentally, outside of a maybe greenhouse-
*pauses, uses Google.*
Um. Or if you knock down a pine tree in the middle of pollen season, and there's a source of ignition.
Apparently. And they got it on video, no less. I'd link, but I'd need to spoiler it, I'm lazy, and you have Google. Edit: Wait, no, that's just the tree releasing pollen. Lame. Still, I imagine that would do the trick if you had an ignition source.
