gonadic io posted:i was reading the OSHA thread a while and there was SO MANY stories of 1 death turning into 10 in situations like that We had "do not enter if alarm is sounding even if you see unconscious people" sign at work. Takes something like ten seconds to pass out if your accidentally get a lungful of no-oxygen, which is scary. Effect could probably be harnessed for ultimate stranglewank by some sort of pervert scientist, though, which is probably good.

In the tunnels we don't have helium/CO2/whatever leak detectors, we have oxygen deficiency detectors. There's several gases used in the LHC experiments so you can' go 'welp, no helium, feel free to work in here'. The poo poo part is we've got argon in large amounts in some detectors, so if you hear the alarm for low O2 you need to think a bit about whether to drop to the floor or try to find some height. Alse, ODH hazard sign is totally the top 1/2 of a dude holding and staring down at his massive dong.

is it true the LHC had to be switched off because someone dropped a baguette into it?

How good is your Helium recovery system there? I recently learned that ours (at a university) manages to capture around 90% of our "used" helium which I thought was pretty impressive, given how janky a lot of the setups are. I only use gaseous helium in my main work and we don't have any recovery system in my lab unfortunately, so once in a while we are forced to waste a shitload of high purity helium when purging pumps or whatever. That always makes me feel like poo poo.

Sweevo posted:is it true the LHC had to be switched off because someone dropped a baguette into it? Apparently a crow or something picked up a baguette that was left out (happens in france, baguettes go from fresh to stale the second they cross the supermarket door, and people often leave them near the trash but not in it for birds/hobos/whatever). Anyway, the bird flies over one of our substations and drops the baguette between the terminals of the 400kV line, and trips half the LHC. This story is as told by the former head of the accelerators & beams division, but he's known for his storytelling style, so grain of salt and all that. Power cuts happen all the loving time in summer though. We get a lot of thunderstorms in the geneva region in summer and it's pretty hard to provide power conditioning/redundancy on 0.5GW @ 400kV. We have a load of 18kV lines too for other stuff like the farm I showed us inpacking. It's possible to get a local power cut/brownout at one part of the ring while the rest is fine. Then it's brown trousers time as suddenly your experiment is completely blind to the status of the beam and you gotta reset your poo poo by hand.

That always makes me feel like poo poo. It's better now than it was. After the massive quench in 2008 we lost quite a bit of helium, but that's mainly because the release was so fast and on such a large scale it had to be vented. There's now more recovery tanks, larger vent apertures and stuff so it should work better but that isn't my area of expertise. Someone asked earlier about the beam dump switch and if it's throw does it cause problems. The short answer is 'not really'. There's two types of situation: Programmed dump and protective dump. The programmed dump happens when the LHC is done with the fill, and there's a handshake procedure where each experiment confirms ready for dump, the state machine cycles through several preparatory procedures then the machine dumps the beam. The protective dump happens in <1000ths of a second and without handshaking but it's still safe, it just takes a little longer to cycle through the preparations to get back to the next fill. Every time there's a power cut, brownout or just a bad hair day for the machine we get an protective dump. No biggie. The bit that takes ages after a protective dump is recovering the postmortem data. Each of the 1000s of beam loss monitors around the LHC can trigger the dump without sending data to the control center. This is because it'd take too long to poll all this and send it around the ring to the nearest fiber. Instead, each one stores the last few seconds of data in a ring buffer. After a dump is triggered by any one BLM the ring buffers of all of them are read out to determine what happened. Takes several minutes to do.
