Change every connection on every device on the planet to USB and watch the world burn. Well, eventually. It always takes me at least 3 attempts to get those bastard things plugged in somehow.

This reminded me of the Underwater Horrors thread, and it's long discussions on delta P. Now that is some scary poo poo. Basically watch this video I guess: https://www.youtube.com/watch?v=AEtbFm_CjE0 Bees on Wheat posted:Someone made this out of parts that shouldn't connect together. By comparison, cramming two tubes together should be trivial. I mean, kids do it all the time with the plastic straws at fast food places. I really want to know what would happen if you plugged that into something. Like, how fast would the ethernet end just melt together and start shorting?

Jabor posted:The solution is to make it physically impossible to connect the wrong ones and have stuff start flowing. That's a few cents more expensive per-unit though, which is why it doesn't happen. lol no it's not. hospitals and providers bitch and moan about anything that isn't 100% compatible with their current equipment and materials with stuff like this. there is a ton of inertia in the healthcare system, and barring a government mandate (which there absolutely should be), no one wants to pay for new equipment that doesnt work with what they have. i know that it's not the same from country to country, though. in some places (france) doctors are especially resistant to "new" things (because they've always done things a certain way and it works fine!), even if every other country has been using them for 20 years and data shows that they're better.

Also, the necessary sizes of tubes are an issue. A ventilator circuit has to be within a certain size range to limit dead space while permitting air flow, usually the diameter of a ping-ping ball more or less. A tube feed line is smaller around than a pencil. If you wanna put a random fuckin tube in the vent circuit, there's not much to stop you. I suspect, though, that it was a fine-tip tube feed connector of the type made to prevent accidental connection to inappropriate tubes... most likely plugged into the small, usually covered hole where aerosol breathing treatments are squirted into the system. Nobody would ever expect something to be stuck in there, but... humans. So the biggest issue to me in hospitals is that for each critical pt there are hundreds of possible ports of access, and making mutually incompatible ports for each of them is very difficult. You aren't talking about two tanks that shouldn't be hooked up to each other, you're talking about an entire room full of poo poo that doesn't go together but could maybe be forced if you tried... But then I've walked in and found family members trying to draw up ground and dissolved pills into a syringe through a needle, intending to inject the results into the IV line by sticking the needle directly into the tubing, because "grandma doesn't like swallowing pills"

Didn't some goon a number of years ago do almost exactly that only with a cable line instead of ethernet because his neighbor was stealing his cable or something and he just wanted to blow up his TV? Then the next day some random house in his neighborhood burns down and he swears it wasn't him and his device? But yeah, it'd short everything out almost instantly. No saving the switch or router. If you left it plugged in, it might start a fire.

Goatman Sacks posted:I never really understood hyperbaric chambers - can you really make a human body just tolerate 9 atm of pressure as long as you ramp it up slowly? And provided you feed the guy the right breathing mix. You're mostly fluid, and thereby mostly imcompressible. The physiological limit to how much pressure you can take is the point at which your neurons get physically squeezed so close together that they stop firing properly or you start getting bone necrosis because the tiny capillaries keeping your bone cells oxygenated start getting closed off.

You aren't talking about two tanks that shouldn't be hooked up to each other, you're talking about an entire room full of poo poo that doesn't go together but could maybe be forced if you tried... You can't really do it with connector size alone, you have to use interlocking connectors that don't allow flow unless they're correctly attached. For example, the connector on the BP cuff can be keyed, so even if you do somehow attach the air compressor to an IV line, it doesn't do anything since the IV line isn't keyed to look like a BP cuff.

When I worked in the oilfields, a safety trainer told me that pin sized ruptures in hydraulic lines could cut you open. That was pretty low on my list of deadly threats out there so I never followed up and learned if that type of thing happens.

Ever watered a lawn with a simple hose? Put your thumb over the hole? Same effect, only with a microscopic hole and LOOOTS more pressure. That poo poo can totally cut you up. And even if doesn't actually slice you, when it has enough pressure to puncture your skin, it'll shred what's below that WHILE also delivering a lot of poo poo into your body that you don't wanna have there. Don't google injection injuries.

You are extremely deformable. Re high pressure lines, I heard a tale (not sure if true) about looking for steam system leaks in a nuclear warship. You wave a broom handle around in front of you as you walk, and when you're suddenly holding half a broom handle you've found the leak.

The Lone Badger posted:You are not compressible. You are extremely deformable. I think that's an old wives tale, but at the same time it wouldn't need to be a nuclear vessel, any place with high pressure steam would have similar issues. Although I suspect that not many places run at the pressures that nuclear plants do. Even our lower pressure reactors run at 10s of atmospheres of pressure, and commercial reactors run at over 130 atmospheres in the reactor loop. Although steam leaks in the reactor loop are pretty easily noticed, what with the loss of reactor coolant and subsequent scram of the reactor.

I need to find those documents on the USS Iwo Jima. Basically there was a break in a 600psi 800°F steam line that flooded the engine room with superheated steam. It killed 10 sailors.

The broomstick method’s job is to effectively communicate the concept that high‐pressure fluids can gently caress you up, and it does that admirably.
