Three-Phase posted:At work we have circuit breakers rated for 5kV to around 40kV that have contacts inside of vacuum bottles. It's not an absolutely perfect vacuum but on the lower end voltages like 4160V they can interrupt like 20,000A of current (nominal flow of 1200A). They are simple and extremely reliable. (I am proposing to retrofit/replace older breakers with newer and even more mechanically simple systems like the ABB AMVAC and ADVAC roll-in retrofits.) Essentially turning them into CRTs?

Pro wrestler with a daredevil gimmick is living the dreamquote:Paul Lloyd Jr., 36, who works here as P.J. Black (Justin Gabriel in WWE), suffered a terrible injury base jumping this past week. He suffered a broken leg, a broken hand and lost a finger. He’s has to cancel all of his upcoming indie dates. He had suffered two broken ankles in October from an earlier base jumping accident while in South Africa

Three-Phase posted:At that voltage level and resultant current flow he was literally cooked. We're talking about massive internal damage that even if surprised could be extremely hard to treat. When you see his body emitting smoke and then bursting into flames the guy is way past any hope. Also he was probably in excruciating pain the whole time until he lost consciousness at some point probably in part due to respiratory paralysis and fibrillation. Thank you for your response! My initial reaction was "oh man why didn't anyone help??" but my gut feeling was "dude was hosed already and they knew it"

Gorilla Salad posted:Just watched this on youtube and it's the first of his videos I really took issue with. Maybe it's because I've done a fair bit of archaeological fieldwork, but this is the first of his videos that made me actually anxious. Incredibly narrow hole deeper than a metre, no proper shoring, spoil discarded close to the edge, no hard hats, no ladders, people loving about standing on the edge of the section, and all while digging in sand. People get maimed and die horribly from making lesser mistakes, these guys don't know how lucky they are.

Built in a less butt-clenching way that would be a pretty rad beach hut to be fair. You could not pay me to go down in that one though.

dis astranagant posted:A followup to that mri video earlier has them quench it (it's being retired anyway) and it all comes out a big fat chimney in a huge butt over quite a bit of time. I saw a magnet quench once at my undergrad university, from the outside (found out what it was well after the event), and it was a big shrieking blast out of a pipe on the roof of the lab. I figured it was a powerful steam vent of some kind -- same kind of noise and appearance.

Three-Phase posted:Yeah rule #1 of rescuing someone is don't become a victim yourself. When I did swim rescue lessons, one of the biggest risks is the person in trouble just going ape poo poo on you and trying to use you as a floatie. You have to warn them before you approach to not to grab you and stay right where they are and not swim towards you. If they start swimming towards you, you need to dive under and swim a bit away so they cant track you and attempt to catch up which would burn out their stamina. This is rescue without a ring I think I have to add. With a ring , it's a lot easier.

The terrifying thing about that is that he doesn't have the integration know-how to design and build proper controls, so he's still using a loving RC transmitter to control it.

Nah, that part is actually just fine, since multicopter flight controllers are generally made to take RC input by default, and transmitters are tuneable, tested and reliable, unlike some homebrew control scheme. The terrifying part is the spinning death-rotors surrounding the pilot, and how unstable the thing is.

If you're on a sour site and see someone go down, yell "man down" and run the gently caress away. don't go back in until help is on the way and you've got a SCBA on. If you see someone get knocked down by H2S and you run straight into help them, now there are 2 bodies to recover.

IIRC that happened just a couple of months ago on a farm somewhere. One guy fell into a manure pit and was overcome by the fumes, and then the guy who went in after him also was knocked out, and so was the guy who went in after him, and all three died. Can't find the article specifically but here's one from ten years ago where four family members and one farm worker all died in the same situation: http://www.cbsnews.com/news/gas-from-manure-pit-kills-5-on-dairy-farm/  It seems like if you work on that sort of farm, having an easily accessible SCBA next to the goddamn hell pit of toxic waste and poisonous vapors might be a good idea

The DIY aviation and this post remind me of an small aircraft fatality here 15 or so years ago where the aircraft emergency landed then tipped over into an open manure pit. Crash didn't kill them, but both passengers drowned in poo poo.

At a flight school I used to be with they had lost a plane to sewage/oxidation pond that was right at the end of a runway. The pilot judged the the wind on the runway by what the GPS gave him instead of looking at the wind socks. The "GPS Wind" is the 3000ft wind which is usually 30 degrees different to what is one the ground and doesn't take into account of the local conditions. He came in too fast and too high. Partially because he had a tail wind and partially he was landing by rote. He insisted in sticking the landing even though he was pass the half way mark before touching down. He applied the brakes but didn't draw back on the throttle. On a grass runway. I believe this was his first solo cross country or very close to it. The plane was written off due to the chemicals in the pond attacking the skin and structure. The impact damage was minimal. No one was injured but much Face was lost. It even featured on the cover of the government aviation magazine.
