One of the videos they showed during my arc flash training was a documentary of a guy who accidentally used a voltmeter on a live 2300V cabinet. The arc flash blew his clothes off and set him on fire. He stumbled blindly through the factory before finally collapsing.
You can do that, won't even hurt. A car battery is capable of providing a lot of amps, but you can't push current, you can only pull it, and a car battery is only around 14 volts.
I wouldn't do it across your chest though, unless you're sure your heart is healthy, and maybe not even then. Even low current can fuck with your heart.
Except in this case it’s not the electric shock that kills you. An arc flash is literally an explosion, creating a blast wave of molten copper and temperatures comparable to the surface of the sun.
I used to do meter work for the Power Company. I was taught that an arc flash would reach 40,000 degrees (F or C doesn't matter, don't ask), and could instantly vaporize tool-steel.
I have a melted pair of pliers to prove it. Luckily, I was probably the only worker who actually used my PPE and was fine.
I guess folks in this thread are talking about different voltages, because I don’t understand how proper PPE can protect you from something that will vaporize your clothes and set you on fire.
Not remotely an expert. While the numbers are crazy big, the time tends to be short. The ppe doesn't have to survive thousands of degrees for more than a fraction of a second. Also it has to route the charge through itself rather than you. Finally, for certain death scenarios successfully working ppe doesn't mean unscathed, it means still alive with reasonable recovery chances.
they're saying people like to crowd around looking at the panel, and that an arc flash will kill everyone there in a microsecond without the proper precautions

Okay, I know this is super dangerous and I shouldn't, but I do want an instant nudity button

I like how they maintained realism by not having the mask explode off of whomever this guy is.

Its both taking a piss and a nod to the comics, where the character would often fight shirtless but with the mask on in that era of the comic.

Yes, almost exactly

Ok. Next time you meet a genie wish for "immunity to all electric shocks."
Defibrillators probably wouldn't work on you. But in turn you can pull off an instant nudity button!

Yeah, and that has the side benefit of fulfilling my lifelong dream to have have my nipples clamped up to a car battery!

You have some wild ass interests, I like it, please report back

In this case it changes so little

English language gets a lotta hate, for great reasons, but on the other hand, it's just so...flexible 😉

Let’s work out that set-you-on-fire bug first though.

Take up acting and get some tear away clothes. Much less painful if you get the crotch seam right.

Did he become a super villain?
CommissarVulpin@lemmy.world · 13 pts · 119d
No…he died.
musubibreakfast@lemmy.world · 7 pts · 119d
But he awoke in an isekai world as a mage and his knowledge electricity gave him an unfair edge
