The criticality alarm, as I understand it, essentially means: run very fast and dont stop, get away as fast as possible. Ionizing radiation release has occurred. Ironic that the scariest sounding one is not this, but the Sellafield Emergency alarm, but perhaps there are good reasons for that.
@@piratecaribou4337 when a large enough quantity of radioactive material accumulates, it will "go critical", meaning vast amounts of gamma radiation will be given off. Walls are no protection, it will go right through most materials, and has caused deaths in the past. So you need to GTFO and hope to god you don't run past the area where it occurred on the way out. An odd thing about this alarm - it was tested monthly, so we were all used to the sound, but it went off one day unexpectedly. It took me a good few seconds before I realised which alarm it actually was, lol!
criticality is when the chain reaction of the nuclear power somehow reached the dangerous point. The point where the reaction is self sustaining and is very harmful. Its the reaction they look for in nuclear bombs
@@imnotaracistokayit’s ironic that the emergency alarm is scarier than the criticality alarm, since when you hear the criticality alarm it just means to stop what you’re doing and run out of the building because there is a lethal amount of ionizing radiation in the area.
Imagine you appear in the middle of the Sellafield plant, you see that everyone else has been evacuated already and can no longer help you, and the emergency alarm is sounding. Just something to help you sleep at night.
I've been trying to figure out the emergency alarm on the guitar. It appears to be a C# minor that bends down into either a C major or a C augmented (it kind of sounds like the top note just goes "flat" to sound spooky). Going down to a C augmented would be like a i-V (minor 1 to major five) cadence, especially if you added the G# in underneath (It's like a i-V cadence that you would get from a melodic minor). It's honestly one of "THE" neoclassical metal chord progressions, so it's a good fit for an alarm that indicates a nuclear emergency that will affect offsite citizens...
@@soundwaves5502 it’s not a train! We don’t use horns like that in the UK. Mostly single tone train horns. It’s most likely an electronic speaker siren produced a tone to replicate an air horn. It might be an SiRcom SiBT siren. A bit like this one ua-cam.com/video/SkCjcu31geI/v-deo.html
I haven’t done the research to know but my guess is, this was long before the modern internet and thus, youtube etc. For people visiting the site, be they contractors or tourists or what have you, it was necessary for them to be able to hear these sounds ahead of time. This is just my supposition, do not take it as anything other than that. I could be totally wrong.
mainly so that people nearby can be educated as to what the alarm sounds mean, so they're not scared/very scared as is appropriate for the alarm they hear 😅
@@chocolate-eclair1234 1. Didn’t you notice the +’44’ on the beginning? That signifies a UK country code. 2. I already called it so you don’t have to. Why did you do that? 😂 Happy Christmas to your phone bill I guess…
@@chocolate-eclair1234 Check out the new version I recorded today, there’s a pop-out card with the new link, and it’s also in the video description. different announcer and slightly different alarms. I called it because of your comment, and in doing so, thought I should record it for posterity.
Because it was recorded from a phone line. You call the number (as listed in the description) from a landline or mobile phone and that’s the recording you get. If they uploaded a copy of the actual recording somewhere, that would be great but this is all I could find, so that’s all we have. The new recording from 2023 that I also posted in the description isn’t much better either. Still on the phone obviously but I thought it might sound a little better in the intervening 10 years…
If your the sort of person who's intellect isn't capable of remembering the meaning of 6 different sounds you probably have no business being somewhere like Sellafield 😂
@@deezelfairy Correct 😂 I worked at Sellafield for over 10 years and I can promise you, we know every single one of those alarms and know exactly when we should be mildly concerned and when we are kissing our butts goodbye. As an FYI, the two that should immediately make you consider making your peace with whatever deity you pray to, are the criticality alarm and the emergency alarm. Those two are either “You’re in the sh*** now” or “Your coffin is going to have to be made of solid lead” depending on the context and your position within the site!
@@sloeginandsleep1170 An odd thing about the criticality alarm - it was tested monthly, so we were all used to the sound, but it went off one day unexpectedly. It took me a good few seconds before I realised which alarm it actually was, lol! It was in B229, and I know of only FOUR people, including me, who actually started leaving the building. Thankfully it was a false one, but two of my mates who worked nearer the exit managed to get across to the changerooms and had got to the non active side before the false alarm message was sent over the tannoy. They were found playing cards in the changing room lol.
@Skraeling1000 This is a very accurate point. When it's drill time, you're just preconditioned to roll with the punches. When it's real, it takes a few minutes to dawn on you 🤣 I wad talking to my son recently about Sellafield and where I went afterwards (Magnox) and he asked how could I work around so much stuff that could so easily kill you. I laughed and told him that there were 5 types of people in that place; the mad, the nihilist, the money guy, the gives no fu*ks and the old timer, who doesn't give a damn about meeting his end in a radiological disaster. They were the ones I'm sure would end up dropping a rollie into a flammable sump and sending us into orbit 🤣

I suspect it's designed to carry over a long distance: a low pitched droning sound will travel further than a high pitched one.
@@hikariyouk true. Intentionally a bit unnatural sounding and designed to alert people very quickly.
More that thiere is or were an uncontrolled nuclear reaction which is bad

Everyone's gangsta until the criticality alarm sounds
Lol
nah that aint scary the emergency one is the real one
@@bornahelmrih94 true, the criticality alarm sounds generic as fuck, the emergency alarm tho, that's ominous
You saying the criticality alarm is scarier? You're either a dumba$s or retard3d or deaf or just a pu$sy, idk which is worst

The emergency alarm is the first audio in a *long* time that has caused my hair to stand on end.
The sellafield emergency alarm, the one with off-site consequences is genuinely scary, but I really like it lol
These are the most '80s noises I've heard in a while.
The real danger is that the content id system claims even this video because some music label made a song of it
Note: Your mutated ears may hear these alarms differently

I appreciate that the area gamma alarm is just a flatline sound.
The second alarm is creepy as fuck
Sounds like a train.
Proper half-life stuff that
Agreed
@@MrVexedviper I think it is one because you can hear train sounds in the background

For some reason it reminds me of the start of I love you how by odetari
1:02 sounds like it could be a NHL goal horn.
Emergency alarm sounds like i could put it into a song.
Don't
do
1:04 i wouldnt be scared i would be vibing
6 different alarms? I'd forget what each one is. Or just think someone had put Radio 1 on.
You don't if it's life or death. This is why this phone service exists to refresh your memory every now and again.
@@c4715 It was a Joke!!
Basically, they all say "RUN!!!!" 🤪
They have changed it again
1:05 A train
song name: siren rapper: siren
It's scary 😱 but if I hear it ima 🏃💨
If u think about it all these alarms were going off at chrysoberyl because all the shit that these alarms mean happened there
criticality alarm is... no doubt getting the message across. Sound is such a powerful tool
For me the emergency alarm is the creepy and i live in England so I’m now kinda terrified 😅
why would sellafield put their alarms sounds on a mobile / landline?
