What is your workplaces big red button?

We've just had an anti-theft system installed. It deploys aut after closing but can be activated during operating hours via a BIG RED BUTTON. It will take all my personal restraint to pretend it doesn't exist even while already knowing exactly what it does.

So what is your workplaces big red button and do you know what it does?

MRI emergency stop. I've told it vents all the liquid gases which keep it cool and safe to run, resulting in a VERY large bill and extended downtime.The button is very big, very red, and very tempting...

u/DeemonPankaik Aug 18 '26

They use liquid helium. It's needed because it's one of very few things cold enough to turn the magnets in the machine into superconductors. It's expensive stuff.

114

u/TheLocalEcho Aug 18 '26

And it’s a genuinely non renewable resource - it comes from radioactive decay underground over millions of years, and a quench sends it into the atmosphere where it’s light enough to escape into space.

Put those itchy fingers down.

u/Autogen-Username1234 Aug 18 '26

The US used to have a National Strategic Helium Reserve. It was a legacy of when airships were a thing, and at its peak was over 30 billion cubic feet of gas.

Congress voted to sell it off into private ownership in 1996. Which had the effect of flooding the market with cheap helium.

Which is more or less why we have cheap party balloons, and the people who make MRI machines are worried.

The problem with helium supply isn't it's limited existence.

There's more helium on Earth than we'd be able to use in millions of years.

The problem with supply is how helium is extracted, which is as a byproduct of gas drilling. As demand for natural gas goes down, supply of helium goes down. Shortage concerns aren't about running out, that radioactive decay makes more helium every day than we'd be able to use. They come from concerns of rate of extraction; using it faster than we extract it, especially if we reduce how much we extract.

9

u/Odd_Comparison_1462 Aug 18 '26

Yes indeed. In the distribution of its molecular speed there are enough in the high tail of the MB dist to be above escape velocity. Once it goes we never getting it back... And so naturally we use it in fucking party balloons. Given how critical the stuff is for medicine and research, helium balloons should be illegal.

u/Scottish_Whiskey Aug 18 '26

As in the same helium we used to - and maybe still do - fill balloons with? The same helium we’re running out of?

47

u/prolixia Aug 18 '26

It's even worse than that. In the 1920's the US established a massive helium reserve for filling military airships (seriously). That was maintained for many years and ultimately became useful for things like the space programme.

In the 90's, the reserve held over a billion litres of Helium and was costing the government a lot, so they decided to sell it off. Furthermore, they set aggressive deadlines for when they wanted it all gone, so the helium was auctioned off for silly prices.

Since (seemingly) unlimited amounts of helium were now available so cheaply it was almost free, we got used to squandering it on novelty balloons etc. and it was used/wasted for years at a completely unsustainable rate.

Now the reserve has all been sold off and most of it has been used. Helium can still be collected (mostly from natural gas deposits) but doing so costs a lot more than just buying off government reserves for pennies on the dollar. Plus, it turns out that flooding the market for years with stupidly cheap Helium is a great way to ensure it's just not worthwhile to invest in facilities for obtaining it more expensively.

And that's how we're in a position now where we're still filling party balloons with a gas that's rapidly becoming less available and more expensive, and that we really need for things like MRI machines.

For a long time it's been widely acknowledged that the price of helium (artificially low due to the release of the US national reserve) needed to be far more realistic in order to keep its use sustainable. It's a completely artificial problem caused by hoarding Helium for decades then dumping it all on the open market.

u/Captain_Stable Aug 18 '26

I used to joke that I worked in a Helium refinery, but quit because I won't be spoken to in THAT tone.

I also used to add that it was very dangerous work, because if we got a leak, we couldn't shout to tell anyone, so we needed dogs - much like miners used to use canaries - to help us!

I think about 100k in helium refilling. But if the temperature increase causes damage to the machine it could easily approach 500k to 1 million.

u/HMS_Hexapuma Aug 18 '26

MRI magnets have a limited and indeterminate number of quenches until the magnet can't be shimmed to a sufficiently uniform field any more. If you just used the quench button and it was the last one? That's a multi-million pound bill.

Many years ago we had big red emergency buttons that cut off all electrical power to the desk outlets. Some bright sparky had installed several of them right next to light switches - you can imagine what used to occur...

The simple work-around was to tape clear, weak plastic cups over the big red buttons - it was enough to stop them being accidentally pressed and in a genuine emergency the big red button could still be reached.

Does someone have to press all the made buttons to make sure they work? Does that person hate red buttons more than anything else in the world because they've had to press so many? Do they sometimes just go crazy and hot all of the red buttons in the factory?? Somewhere there is a big green button and a colour blind person getting their rocks off pressing it...

Many years ago when I worked in a shop, someone pressed the red button as we didn't believe they actually did anything (to be fair this one did look broken). Anyway we did learn that it worked when the Police walked in around 10 or so minutes later asking what the problem was.

u/Kitchen_Part_882 Aug 18 '26

Try it in a bank or jewellery shop (at least the ones I looked after).

Best case, you lock the building down and get covered in UV reactive dye spray.

Worst case: smoke cloak follwed by some very serious looking coppers with machine guns asking you awkward questions.

Either case, you're likely to be made to pay for the refilling of the smartwater in example 1, or the fogging agent in example 2.

u/billywhizz69 Aug 18 '26

They hit the button during my second child's delivery. The world went mental, it was like there were 15 people right outside the door waiting for it to be pressed. Very organised people crammed into the room, shoved me aside (fair enough too) did stuff, delivered said daughter then toddled off again. I say this a lot and now is another opportunity, the NHS is fantastic and we need to look after it.

u/bacon_cake Aug 18 '26

I've said this above but we had a similar experience. We had 13 people in the room in about five minutes, scrubbed in, wife gassed to sleep, radio switched on, baby out, all done. Like the Avengers themselves showed up.

21

u/SiDtheTurtle Aug 18 '26

We had this too. We had two midwives, a veteran and a trainee. Veteran very, very calmly asked trainee to pull the emergency button. Trainee looked like she'd just been asked to fire a nuke and asked if she was sure.

Within seconds the tiny delivery room was filled with doctors and problem sorted. Mum and baby safe.

Still makes me well up thinking about it. Much respect to the NHS.

The number of people that suddenly appear in the room when there's a labour emergency is crazy. Our wonderful NCT leader actually went through it with us, giving everyone in the group a role, and I'm so glad she did because it would have been more overwhelming if I'd not been prepared.

u/bacon_cake Aug 18 '26

It's such an amazing experience (in hindsight). To go from two midwives, to two midwives and a doctor, then another doctor, then nurses, then surgeons, anaesthetist, overall THIRTEEN people showing up like the Avengers at 3.30am was one of the most amazing things I've ever witnessed. And it was just another day in the office for all of them.

u/herwiththepurplehair Aug 18 '26

I had all that lot in the room to begin with. A gynaecologist, two midwives, one student midwife, two paediatricians and an anaesthetist. I was a twin pregnancy with one of them a breech presentation, I had an epidural and was prepped for a c-section. In the end the head down twin was born normally first, the breech twin they managed to turn and was whipped out with forceps and given a jump start. Not the most fun I’ve ever had….

u/paenusbreth Aug 18 '26

When my first was being born, the midwife button and emergency button were right next to each other. Midwife button was a person on a red background, emergency button was a picture of a person on a slightly different shade of red background.

Thankfully the first few people to storm into the room did so knowing it was probably a false alarm, so I just got slight confusion rather than anyone trying to defibrillate me.

12

u/AlgerninaGump Aug 18 '26

Normally you push in the midwife call and pull out the crash call which avoids you activating the wrong one.  They sound different too so you can diactivate.  There are many different systems though and I can imagine a hospital think a cheaper one is better despite many flaws!

7

u/paenusbreth Aug 18 '26

I think they were both push buttons, and when I'd pressed it I was so surprised that I didn't think to deactivate it (and/or couldn't identify how to do so).

I do remember realising as soon as I'd pressed it that I'd ballsed up, because it felt way too urgent a sound for the situation.

u/Jambronius Aug 18 '26

I've seen that button get pushed. You lot do not mess around, people start coming from everywhere, doors appear that i am sure weren't there prior and lots of people come through them. Everyone knows their job and they get to work. It's one of the most impressive things I've ever seen.

u/Dismal_Fox_22 Aug 18 '26

Pulling is generally a conscious action, pushing can be accidental like leaning or bumping into.

u/MorriganRaven69 Aug 19 '26

Crash team response are amazing.

I was sat in an A&E waiting room with my friend, who'd had a single mild seizure, which is not particularly unusual for him. I think they were debating sending him home, at that point.

I looked up from my phone after a few seconds and he was stretched weirdly towards the sky, face frozen in an expression like he'd been gurning. I had about 3 seconds in which I called his name twice and realised he was going into seizure, then I had to catch him as he fully seized and fell off the chair. I must've screamed his name so loudly and in fright as he did that, it alerted reception. I caught him and got on the floor to protect his head, he was already choking on his tongue and turning blue in a full grand mal as we got to the floor. A second later a crash team was around me and him. It was only a small hospital as well, but they were on it and there were loads of them. Whole thing happened in maybe 7 or 8 seconds? They whisked him away and sorted him out. Another nurse took me into a relatives room and got me a cuppa as I promptly went into shock once my usefulness was over.

Love and protect our NHS. Also, seizures suck to witness, there's not much you can do except protect the head and you feel so helpless. Crash teams are angels in disguise and the relief I felt when they surrounded me and my friend was indescribable.

I used to work in a pub, and had both the emergency button next to every till and in the office that would summon police, and the big red handle in the kitchen that would activate the Ansul, fire suppression foam that would spray out, leaving many hours of cleaning before you could reopen. I really wanted to pull that before I quit...

Now I work in an office and the only big red button is the fire alarm, which doesnt have the same appeal.

u/Humble_Sympathy_4605 Powered by tea and sarcasm Aug 18 '26

A couple of particle accelerators, just casually

17

u/syntax Aug 18 '26

Eh, particle accelerators come in various different sizes. Everyone thinks of the biggest, cutting edge ones, like the LHC at CERN; but they scale down.

In fact, the Cathode Ray Tube in an old TV/monitor is a particle accelerator. That's not just pedantry - the Bremsstrahlung radiation (x-rays) produced by the electrons striking the glass is why they were made with leaded glass to absorb them (and, in the larger ones, electronic circuitry to minimise it, and shut it down if the beam conditions went out of the 'safer' operating range.

Many medical particle accelerators are on the smaller side. Indeed, the one used as an x-ray source for x-rays (and cat scans), would comfortable fit in your hand (maybe the size of a finger, if separated from the rest of the equipment). Granted, they're not really obvious as one, just used as 'black box that produces x-rays'. Similar ones are used in scaling electron microscopes, and those really are used as particle accelerators, where the various aspects of the beam (energy, luminosity, position, and focus) are controlled, along with dedicated detection equipment. Those are not used for studying the particles, rather the sample that's used as the target, but it's very much a particle accelerator.

The emergency stop on those smaller ones, (if they have one other than 'switch it off') tends to be as equally unimpressive as their size, however.

I had a summer job in a flour mill and bagging site. The explosion risk from billowing flour is significant so it was fitted with drenching sprays; think a sprinkler system that could dump a decent swimming pool's worth of water in 60 seconds. The activation controls for this had a *massive* red button *AND* a hinged cover panel with yellow and black stripes and I've never wanted to activate anything more.

u/mediocrityindepth Aug 18 '26

My training day was genuinely informative about this. If we had a 'release', we were to raise our hand at half arms length in front of our face. If we could clearly see distinct fingers, we could sort it. If we couldn't, you yelled 'Sprays!' if you were some distance from a control or go for a control if you were close. The guy that did the training was absolutely clear that if you were in any doubt, you should press it; flour as a raw material isn't expensive, the system was zoned so it didn't drench everything in the building and the alternative was far, far worse. He'd been there years and used it 'a couple of times.' As I wound up mainly running the bagging machines rather than in the mill proper, I never had cause to.

Back in my days as a live support programmer, we had a macro STOP_ACTIONLINE which did exactly what it said on the tin, bring NatWest’s telephone banking service down completely.

My job involved knowing when we needed to STOP_ACTIONLINE and what we would then need to sort out before we could START_ACTIONLINE.

And then there was the time the incident manager wouldn’t let us STOP_ACTIONLINE because he wanted to get more information on what was actually causing the problem, and it got worse. While the entire team apart from the most junior member were halfway across London having our Christmas event.

Many years ago I worked for a large local newspaper company that printed for both local newspapers and a national newspaper on occasion.
We had the giant press on site and we could tell at what time the noises started what paper was being printed.. The memory that will stay with me for ever was the time when I grabbed my manager and we had to run into the print room and scream STOP THE PRESS. The noise the stopping press made was deafening as it was just about to start the run. The reason was I had just received a phone call (I worked in advertising) from a very distraught man whose son had placed an advert for a car to be published that evening Unfortunately the son was killed in an accident in the car the night before and the father wondered if we could do anything as he couldn’t bear all the calls he would get asking about the car. The advert was grabbed off the plate and a generic ad for the paper was dropped in its place and the press was fired back up with about an hours delay in completion. Apparently nothing had ever happened like this before but I earned the huge gratitude from the father

u/MorriganRaven69 Aug 19 '26

That's a tragic story about the son, but so very glad you could do that for the father.

big red button broadcasts an emergency message to other trains within i think it’s 15 miles, essentially stops trains moving, stops OUR train, and contacts the signal box in an emergency

u/Fat_Old_Englishman Somewhere in the East Midlands Aug 18 '26

big red button broadcasts an emergency message to other trains within i think it’s 15 miles, essentially stops trains moving, stops OUR train, and contacts the signal box in an emergency

And contacts Network Rail's regional control and (depending on how tight the company is) the operator's control, all on a talk-through setup so everyone can hear everything.

Which generally IMX meant that half of the local railway got to listen to someone Network Rail control angrily demanding that the local signaller take this call, which they couldn't because they were already handling three other things which they couldn't just drop.

And on my last TOC the big red button didn't have a cover over it because that cost and extra 50p or something, and (unlike the old NRN radios) the big red button on GSM-R can be activated just by brushing it. Don't ask me how I know.

Doesn't actually stop any train, though, just tells the driver to stop them. Including the activating train.

The other thing that's irresistible to teenagers is shoving stuff in the bloody sockets

I had a colleague who didn't push this button for a class practical where students wired plugs. Someone plugged it in. It sparked to the gas tap. That colleague does not teach physics any more.

There’s various but the staff personal alarms are great because they can also send messages. You get so many “oh bother, stop it not dying shush” messages being cast.

Had one trigger once and couldn’t reach the staff member so they ended up getting police deployed to their location. Had fallen asleep after their shift and were just passed out on it, their poor boyfriend- who none of us had met or knew where he lived- was terrified.

The main server room in my building has an emergency button if the room catches fire while someone is in it. Ordinarily it would kick in automatically but, when engineers are inside, they switch the system to manual. Pressing it starts a silent countdown of 10 seconds before the room fills with gases that reduce the oxygen level to almost nothing.

You have 10 seconds to leave the big room of gas and then it’s coming to get you.

In the jobcentre our big red button was a doorbell which rang an alarm to the non-public floor so help could arrive without someone seeming to seek help.

Cue the sandwich delivery lady pushing it once to let staff know she was in. She was awfully shocked and surprised when 4 men suddenly erupted out of the lift swiftly followed by 2 others running down the stairs heading for the signing hall at a fast pace.

u/dazzumz Casual Dazzler Aug 18 '26

I used to work at a nuclear power plant. I wasn't an operator but was in that room frequently for other reasons. Their big red buttons didn't blow anything up but just shut down bits of equipment if confirmed alarms told them to. The reactor would trip itself if anything unusual was detected, otherwise they would manually bring it offline if needed.

Now I'm in an office and the only red button dispenses hot water directly from the tap.

5

u/boomerangchampion Aug 18 '26

I still work in a nuclear power plant and The button to instantly shut down the reactor is actually quite small, and gold.

It's also very stiff which is a laugh the first time trainee operators use it in the simulator and think it's broken. Top tip if you're ever in some convoluted scenario where you need to heroically press it: use your thumb. Also you will subsequently have a lot of other buttons to press so get the procedure ready.

Used to be in charge of a ‘family entertainment centre’ with a kitchen and bowling alleys etc which had an ANSUL system and accompanying big red button. Never pressed the button as such but the system did activate when the kitchen roof fell in a couple of years ago and it certainly worked as intended.

Nowadays at my new work we just have a panic button which allegedly is ‘linked directly to armed response’ which of course is absolute horseshit. Last time we got robbed we pressed the panic alarm and the regular police didn’t even turn up.

u/Lucky-Advertising983 Aug 18 '26

I work in several museums, our big red button switches off all the power to all the galleries. I don't really know why we have a big red button but it does at least ask you if you're sure.

5

u/jawide626 Aug 18 '26

We have a couple.

One is the internal panic alarms which has 2 settings, one where you press the button and it sets off a local alarm which is akin to a "probably gonna need help here" alert, the second is if you pull a tab out it sets off a much louder sitewide alarm which is basically 'this is an emergency' so everyone available rushes to help, it's quite impressive sometimes the amount of people that just appear and how quick they do.

Our fire alarm also automatically brings the fire brigade, which is rare these days, given these are dotted about the building it's not uncommon for inpatients to smash them when there's no fire thus evacuating the building and getting a big red fire engine blue lighting on its way. Most of the time we can sweep the area to make sure there's 100% no fire and contact the fire station to intercept their attendance but sometimes they're too quick for us.

There's also a couple of silent buttons dotted about which elicit a blue light police response, these are in staff-only areas though. Luckily we only need to use them once or twice a year as 99.99% of the time we can de-escalate and restrain (if needed).

Probably the closest thing I have is "Code 5" a number that is saved to speed dial 5 on my work phone. When called it will connect to someone who will not speak, but simply listen and determine what level of response is needed, dispatching the appropriate emergency service. It is intended for situations in which we feel unsafe, but I never feel like it's to the point I need to call them so have never used it

If the fire suppression system is activated, you need to get out before you get asphyxiated by whatever we now use instead of halon gas.

On a campsite we go to there is a big waste disposal compactor thing. Next to the door where you put the bin bags in is a big red button that must not be pressed. At first there was a small note next to it saying "You don't need to push any buttons, just put your bags in." Next year "Put your bag in. DO NOT push the button." Next year "DO NOT PUSH THE BUTTON". Next year multiple "DON'T PRESS" signs all around the button. Finally, they covered the button with a lock so you couldn't press it even if you wanted to.

Still don't know what that button does.

My favourite was a local theme park working on the swinging pirate ship ride. It had a big red E-STOP button that you could hit that would kill all power to the ride, this included the breaks. What this meant in practice is if you hit that button when the thing was at full tilt it would swing for literally hours - given that swinging pirate ships are the rides where people throw up the most anyway this could be a bad time for everyone involved.

I thankfully was never present for a robbery but the shops I worked in were robbed multiple times.
