RIP fire triangle welcome fire square
Daniel Asher hol up what?
Fire triangle was the thing for decades... wikipedia has an article about it... which is this fire square without the chain reaction part. The article also talks about a "fire tetrahedron" I never heard of which has the chain reaction as one surface.
*tetrahedron. Looks like a tri-force.
I subscribe to the fire trapezoid theory.
Actually the chain reaction should be in the center of the triangle (or the triangle itself).
Heat, fuel and oxidizer cause the chain reaction to happen.
Cody, 20 year Fire Fighter, and I have seen what happens to someone huffing this gas. They died, as the gas is small enough to replace the oxygen in the blood and then the gas does not want to leave the blood, and lungs (due to the weight of the gas)

@@abhisheksoni2980 I don't think that that's how it works.
misc channeler well gravity tapping in pneumonia patients works that's why I asked..
Abhishek Soni Pneumonia is far different from gas inhalation poisoning. The only thing that could possibly help a low exposure of Halon 1211 or 1213 would probably be immediate treatment of high concentration of oxygen in a hyperbaric atmosphere, similar to the treatment of carbon monoxide poisoning, although this statement is in theory only and hasn’t been proven, at least not to my knowledge. Halon, like carbon monoxide have a far greater affinity to bond with hemoglobin, therefore displacing the oxygen to your blood cells. In theory, positioning someone with heavy gas toxicity upside down would only cause the heavier oxygen deprived blood cells to reach the brain faster, exacerbating the condition to an anoxic brain injury. Do not, under any circumstances ever inhale this, or any other potentially toxic gases. You will die.
Well nobody is going to prove this guy wrong lol
On the first day of my apprenticeship I was in a substation with a halon extinguishing system. Not quite as cool as the DC switching hall with the knife switches, Frankenstein meters and the biggest mercury rectifier I've ever seen. It was all part of the 500V DC buss for the traction plant in Glengarnock Steelworks.
bigclivedotcom call me stupid but I understood 3 words of that sentence
That must have been many, many many Christmas's ago 😀 I did some ceilings at a missile factory near Kidderminster and they had a halon system, we had to have a 4 hour induction on all the hazards

Yeah, no Cody, don't breathe that stuff, mkay?
THIS is exactly what I was thinking when he started talking about how heavy it was.
Ever read BOFH? Halon can kill, please don't breathe this!
In a section on substance abuse in my pharmacology degree they listed a bunch of commonly abused inhalants and IIRC both freon and halon were listed on there. So even if it doesn't kill you I'd imagine it would severely impair your judgement and potentially cause neurological damage. Add to that the risk of sudden cardiac failure ("Sudden sniffers death") which seems to be a risk shared by all abused inhalants (except nitrous oxide, xenon and medical anesthetics). By all means drink cyanide and play with mercury, but inhaling halon would be one to leave off the list! :)
Rob, Halons are not biologically active. They are, however, commonly abused. Breathing any inert gas reduces oxygen uptake causing lightheadedness. One typical abuse technique involves bleeding refrigerant from air conditioning equipment (to the consternation of homeowners) and inhaling the gas directly. This gas also contains a lubricant mist that can cause chemical pneumonia in addition to the potential for immediate suffocation.
I'm no pharmacist but I did focus on amateur pharmacology back in college.
I used to breathe it all the time... had some MAD hallucinations but I'm still here, about 30 years later.

"Now this is a balloon filled with air. You guys have probably seen these." -Cody
I've worked in datacenters that had Halon 1301, but I was never around a discharge. However, one data center I worked at had a discharge of FM-200. The FM-200 was installed in 1998 as a new system. We had a contractor that thought if the key in the fire panel was set to "override", it would prevent any potential discharges. He was right, with regards to the DETECTION, but manual pull stations were always on. Well, he apparently unscrewed the pull station, tripped the switch, and we hear the discharge buzzers, and what sounds like a jet flying by (the gas through the plumbing). I run out to the datacenter, and pop the door to see the contractor guy holding the pull station in his hand, with a fog everywhere, and a dumbfounded look on his face. I'm like "What happened?? Get out of here!!!" - but it was funny because my voice was like Barry White up in there, and normally I'm a tenor. It was funny, except for the fact that a discharge was like 25k$ in gas (so I was told)... FM-200 was substantially less toxic, and didn't have the breathing apparatus requirement. I was told that the gas was "safe" unless it interacted with a fire directly. Might be interesting to do some more comparisons with other fire suppression gasses in other videos. Keep up the content!
James Bass We had a similar system in a server room and the room above had massive cylinders that just dumped through the ceiling. Used to scare the daylights out of me because the door was a swipe card to get out as well as in and you only had a limited time. Never went off though.
James Bass Wow! $25K! I definitely can’t afford a similar system for my electronics lab...
Small 250lbs tanks cost 2600 to fill. Dont ask me how i know.
What was a contractor doing messing with the clean agent pull station? Unless he was there to work on the system for inspection, sounds like that guy had no training otherwise. Surprised the server guys on site, or the building maintenance let him do that. Also, The keyswitch for the disable does kill power going to the discharge actuator on the tank, it does nothing to stop detection devices from functioning. So something else must have happened to fire it as it has no power otherwise. The way you describe it, sounds like it still was in normal function, since the panel went through its normal process to discharge.
Electronic door locks are typically disabled automatically when fire suppression and alarms are activated. They require power to stay locked. The suppression system cuts power to the doors when activated and provides a fail safe. This is assuming everything has been installed correctly and tested.
while i would love to hear your voice when breating halon i would seriously advise against inhaling halon 1211 as it has been found to be a cardiac sensitizer in animal studies.
The following is taken from a halon 1211 msds:
"Acute: Inhalation-Rat: At 50,000 ppm, no effects were noted. At 75,000 ppm, slightly accelerated respiration was noted. At
100,000 ppm, mild excitement was seen. At 200,000 ppm, within 1 to 2 minutes marked excitation and some convulsions were noted. At 60 to 90 minutes, 2 of the 4 animals died. A concentration of 300,000 ppm immediately gave rise to convulsions and narcosis and all animals died within 50 min. Inhalation-Dog: At 25,000 to 75,000 ppm for 3.5 hours, there was reversible myocardial lesions and fatty degeneration of the liver"
but ....cody isnt a rat so it must be safe :P
Yeesh. Sounds nasty.
Lots of warnings such as these in the server rooms with Halon system in the various places I have worked. Very nasty stuff.
@argy the gasmasks didnt work on the mustard gas they had, which was easier to reproduce than halon at the time, but yes it would have been awful
It's a different gas but, back in the day we used to have Halon B as a fire extinguisher for datacentres. Essentially we were told if there was a fire, RUN as fast as possible because once the sensors were tripped that there was a fire, those doors close and the halon is released, and you're dead in seconds. I.... wouldn't mess with it.
Instead of breathing it in, couldn't you just make a "balloon fart"? When you pull the ends of the balloon's opening so it makes a squeaky noise, the noise should have a lower pitch when outputting halon, similar to the vocal cords.
IndieMarkus oooh that's an awesome idea actually
THIS NEEDS TO HAPPEN
Actually, the pitch (fundamental) of the vocal chords does not change appreciably. You can verify this by making a spectrogram of the audio from Cody's video where he breathes in all the gasses one after the other. Although it sounds like the pitch is going up or down, the actual note is still pretty much the same!
What the changing density of the gas does is change the resonance peaks of the resonance cavities (e.g. mouth, nasal cavity) to lower or higher frequencies. Essentially, it changes the *timbre* of the voice (much like a piano playing one note, sounds different than a flute playing the same note), not the actual note/pitch.
@@RoaldFre is that timbre? When playing the same note on a piano and a flute, neither sounds higher or lower in pitch, though they have a different "voice" or timbre for sure. Your description of the gases changing the amplitudes of the peaks of the resonant frequencies sounds right. If I understand correctly, the voice sounds deeper because the lower frequency components of the voice are amplified more than normal? Like you said, that's not making the voice lower pitched, it's just an illusion, but I don't think that's timbre. Timbre is more like the quality or character of a note, nothing to do with pitch or apparent pitch
Yes, I would say that this is indeed an example of timbre (which essentially is determined by the relative strength of the overtones above the fundamental). For a dramatic effect of timbre that seems to modify the actual pitch, check out some videos of 'overtone singing' (Anna-Maria Hefele is a well known overtone singer).
Here, the singers shape their resonant cavities in such a way as to maximally boost a particular overtone (an integer multiple of the fundamental), which makes it sound as if they sing a higher pitch above a constant 'drone' of the fundamental frequency (this drone is the actual pitch of their vocal folds).
Alternatively, a really twangy/nasal sound (e.g. 'eeeeee') sounds sharper to our ears than a round, warm ooooh sound at the same pitch. Although a musician should still identify them as being the same pitch, I would say that the 'eeeee' sound does have a 'higher pitched' quality to it than the 'ooooh' sound.
Me = ten years in gaseous fire extinguishing systems for manufacturer and installer.
1211 = toxic at low concentrations. Only it's main manufacturer used it in total-flood room systems. Otherwise it was all in portables.
1301 widely used in total-flood at 5-6% by volume. Not toxic until 15+%, unless decomposed by fire. One insurer asked us for examples of a system being used to actually put a fire out - we went back through two years of refill records and they were all non-fire discharges!
By late 90s it was the data that was more valuable than the computer (room), so high sensitivity smoke detection became the better choice and then just turn the power off to the kit - everything was low-flam anyway. I went postal - well, actually worked for Royal Mail for three years, before getting a job for a bus manufacturer.
Phillip Bicknell i didn’t need your whole life story bro
@@alfinito44 I liked it so you can shove off!
Explosively actuated valves on those systems?
Globe Science What’s your problem man
"two years of refill records and they were all non-fire discharges" - so basically you install a total-flood system and fires won't just happen there, quite effective.
Always wondered what fits a fire extinguisher outlet.
Got lucky with that one. I know that Amerex FE's use proprietary threads.
Only so many ways you can make a right hand thread that works. Turns out that using some thread that already exists as a tap and die nut set is going to be a lot easier than machining them out of tool steel and hardening and grinding them.
Do not breathe Halon 1211, it is so dense that it will still be in your lungs for hours, and as it does dissolve readily in polar and non polar solvents it will stay in your body for a long time. Breathing in the byproducts of using it on a fire is also deadly, it breaks down to form hydroflouric acid amongst other things, and hydrobromic acid is still almost as nasty.
The thread is a NFPA standard for fire equipment and very very hard to find any kind of connectors. This is intentional as if you can't connect to them then people will leave fire fighting equipment alone.
i just re tapped it
SeanBZA would a childish solution like hanging upside down and breathing out work, or is the inner surface of one's lungs too porous or something? Either way sounds like a bad idea.
Why I love Cody’sLab: I wouldn’t know halon existed let alone see anyone mess with it!
I learned about Halon from Terminator 2, still cool to see Cody providing some extra info on it tho.
I learned about Halon when my dad got his job at the hospital in the computer department. They have a massive Halon Deployment System warning sign outside all the entrances to the Server room. Basically telling us humans we will die in that room if the system goes off hahahahaha. But it is an excellent fire suppression system to protect electronics without much collateral damage to the surrounding rooms.
I learned about Halon from Breaking Bad, RIP Walter White
Still a market for it, in aircraft ( where it is about the only thing that can put out burning aluminium in a hand holdable form) and in space applications. Nothing else comes close, so there is a massive bank of the stuff around for these applications, and while the price is high, this is still used. Just that they are a lot more careful in servicing, and scavenge the gas out wherever possible because of cost.
Also in large server rooms too. Don't want to destroy all of your equipment when the system goes off. Though new installations are usually some other gas that's not as bad for the enviroment.
So I’m genuinely curious, how does such a heavy gas get high enough into the atmosphere to cause ozone to break down?
Sad to see no one bothered to answer this.
While halon does react with ozone to destroy it, you are right to observe that it will have trouble reaching those altitudes in bulk at the scale shown here. However, as the gas is released to the atmosphere, it will diffuse over time so each molecule will be separated from its buddies and become more easily carried off by surrounding air as it the concentration of halon in the air decreases. This means that if, say for example, a factory released large amounts of halon pollutants into the air over an extended time, this would quickly become a big problem. Since halon is somewhat inert and won’t be destroyed in the environment very quickly, non-trivial amounts would make it to the ozone layer.
It's because astronauts used too many fire extinguishers to try and put out the moon and it all drifted down on top of the atmosphere
Its still a gas..... So it will easely mix with the atmosphere if there is some wind around
@Fungo Slungo Yes it does.
That's one of the reasons why earth is flat
“So I put some fruit flies in a jar of this gas to see how long they lived”
I’m somewhat of a scientist myself :)
Could you mix a coloured smoke (in air or lighter gas) with the halon and observe waves like a fluid before it diffused?
I would love to try stacking different density gases. Just have to find a smoke that will work..
try a very fine colored powder?
@Cody'sLab Speaking of stacking, what happened to the 100 layers of liquid video you wanted to make?
I was going to do it at salt lake comic con and get the world record people involved but they have stopped communicating with me.
They’re afraid of your knowledge, Cody
This is how Cody meets his end - breathing in Halon because some jackass on YT comments said it was okay.
it's okay
And he won't take advice on not inhaling it without citation lmao self preservaton isn't his thing I guess. Inhaling potentially fatal HALON 1211 it is cause I'm too stupid to listen to people

WAY back in the "old days", this was a common fire suppressant used in big data centers. I'm talking mainframes that were quite expensive. I worked in such a facility, sometime early 1980's. The halon would kill fires without killing the expensive hardware. But we were all warned (and there were signs all over the place) that if the halon was ever discharged, get the hell out of the space immediately and evacuate the building. But I have no idea if it was Halon 1201, just know that it was not good for you.
Actually, every gas labeled as "Halon" produces extremely toxic gases if decomposed.
Yes it was
we were told it would settle your lungs making it impossible to get enough O2 because the halon was in the way
I saw a mythbusters video once where Adam breath a heavy gas. To make the gas out of his lungs he had to stand upside down.
Ken Davis, very interesting, thanks for sharing. I know it was (is?) also used in large electrical facilities by power companies.
I thought they used argon for that? Could be wrong. Back in the 80's as a 17 year old I did some work experience with a pharma company that had a room full of IBM mainframes. They had similar warning signs and oxygen masks.
hi cody, i used to work with halon 1301 in large scale automated systems protecting computer rooms etc. back in the 80s. while we were exposed to small concentrations of 1301 on a regular basis our chemist always warned us to avoid exposure to 1211.

I to worked with Halon, mostly 1211. I was exposed to plenty it of over the decades usually in lighter concentrations, I could be wrong but as far as I know the guys I worked with and myself have suffered no ill effects. Not a recommendation. Halon was touted as supporting life vs Co2 not.
@@brettsalling This actually does exist, but not with halon. Oxygen reduction systems using nitrogen have been used in Europe for years to reduce fire risk in warehouses.
This may be a dumb question but if the gas is so heavy and it has to be heated to the temp of molten iron to float how's it going to get to the ozone layer?
just guessing but is dense as a pure gas but then it mixes with the atmosphere and individual molecules can be carried up
The halon is just a source of bromine ions (when UV breaks it down). Those are what does the damage.
Halon is broken down to bromine ions by the uv rays from the sun the bromine ions deplate the Ozone
some people should read the questions before they answer: this one is about how the gas gets to the ozone layer, if it is so heavy, and not why it can deplete ozone for chemical reasons.
It is definitely too heavy to have a bubble of it floating up to the ozone layer, that would not happen because of the density. However once two gases mix, single molecules can diffuse almost anywhere, even into high altitude. The chance of finding a Halon 1211 molecule in higher atmospheric layers (which is nothing else than proportional to its concentration) decreases with height, which still is due to its molecular weight (the molecules gain a higher impulse upon acceleration down to earth due to gravitation between two molecular collisions).
In the end its a statistical process which way one molecule takes, but over time due to entropic reasons enough will end up in the ozone layer. once there, they can react to different molecules, which may be lighter. Br and Cl atoms can stay there for a loooooong time then, but that you do probably know already :)

Cody, maybe you could record your voice and then play the recording through a speaker submerged in the Halon? Would that work?
Probably not, but I like the angle you are working with.
TerminvsEst Why wouldn't that work? It's just modifying the frequency that your vocal cords project, it doesn't affect the actual vocal cords. Theoretically a little register bell should sound like a cowbell
PeriodicVideos tried that (I think it was with Hydrogen) to simulate the professor's voice after breathing Hydrogen, but rather than making the recording higher pitched, it just muffled it.
when your vocal cords vibrate it is an interaction with the gases around them that produces the vibration. if you change the gas you change the interaction and therefore the pitch of the sound that gets produced. electronic speakers and bells work differently. the speaker has the current in the coil switching on and off at the frequency that they are programed to use, this frequency wont change just because the environment changes. you get reflection of the sound waves at the edge of the gas but the pitch stays the same. Bells vibrate at a resonant frequency that is determined by the shape and mass of the metal so they wont change pitch either. but flutes and some whistles would probably change pitch. You might be able to release the gas through a whistle to hear the difference.
Excellent idea! I wonder if Cody could play a set tone and then measure what it drops to. Maybe there's a calculation on air density vs tone pitch.

Its global warming potential isn't too much of an issue due to its relatively short atmospheric lifetime (comparable to that of the GWP for R-134a in canned "air"), but 1211 is an INCREDIBLY powerful ozone depleting gas because it contains bromine. It's 8 times more destructive to stratospheric ozone than CFCs. To put things in perspective, a single molecule of 1211 will destroy nearly a million molecules of ozone and thus the release of that one balloon's volume will destroy a volume of stratospheric ozone far larger than the volume of your house (owing both to its intrinsic destructiveness to ozone and to the lower density of air in the stratosphere). While I think the pedagogical value in doing experiments like the ones you do for us here on youtube very much more than justify such a loss, at the same time I would like to see you somehow pyrolize future releases such that they are rendered inert with respect to potential ozone depletion capability. It could probably be an educational video all its own.
Would bubbling through a solution of NaOMe methoxylate the bromide?
Might be a easy way to destroy the stuff
If, like me, you were skeptical, do look it up; it's one of those cases where it acts as a catalyst, rather than directly bonds with the ozone, and also isn't stable enough to hold onto the oxygen, renewing itself; this is why it is capable of depleting so much ozone.
Yeah it wasn't till after I had everything filmed and really couldn't change it that I realized that ozone is a greenhouse gas and removing a bunch of it by catalytic destruction will actually reduce the green house effect.
Kain Yusanagi indeed. Cl and Br radicals are produced by UV degradation of 1211 when it diffuses into the stratosphere. Once there they catalytically degrade O3 into O2:
X + O3 -> XO + O2
XO + O -> X +O2
------------------------
Net: O3 + O -> 2O2
With X = Cl/Br.
As you pointed out, X is regenerated so many cycles can occur before the radicals are eventually quenched. These quenching reactions are very slow, especially so w/ Br, making them very persistant in the atmosphere and thus the high ozone depletion potentials.
You bring up a good point. He doesn't really make chemical disposal videos.
It definitely makes your voice deep. Had a halon bottle go off in my HMMV on patrol. Hit me in the back of the head while driving.

Halon will literally absorb the oxygen out of your lungs if inhaled in concentration, you have a few seconds until you pass out and 30 seconds until brain death occurs.

Hey Cody, did you run a control experiment by also putting fruit flies in a jar with a non-toxic air displacer?
r77xxl wait what?
He added halon to a jar of fruit flies, and the fruit flies died within seconds. I was wondering whether that's because halon is poisonous or merely because the fruit flies suffocated. Upon review, it seems he didn't even make it pure halon, so it almost certainly is toxic to fruit flies.
Lol
Scrimpton 01 flies probably died because halon displaced air and they're just suffocated, not because it's toxic.
I have seen incects survive no problem over 24 hours submerged in water on only the air trapped in the hairs around the body... Add a little soap and they die within minutes or seconds.

Alexander FL-TS if i can get the chemicals I might have to try that
Are you going to do a methane digester part three? Or did you discontinue the project?
Pretty sure in a video during the winter he said that the methane rig he setup died because it got too cold so things stopped breaking down organically.
i know in a comment on another video cody replied to someone telling them he did something that made it stop working.. i think it was that he used tap water and that killed the bacteria. i could be wrong though
For working on fire extinguishers Ive learned from use and what Ive heard, halon 1211 is one of the best to put out a flame but i did not know a lot about it and this video gave me some more info about it! Oh and it rusts bare steel from what I’ve experienced from tearing these apart always love finding new things out.
That bit at the end with the floaty boat and the candle snuffing...super cool. I occasionally use your videos in my 3rd grade science class Cody. Thanks for making them and thanks for the first-rate YouTubing.
HA - but do NOT use HALON with your 3rd graders.
You know who could survive inhaling Halon?....
Halon Musk...
Up!
No one knew that Cody made the hole in the ozone layer!!:)
However, if it weighs 7.2 grams per liter, I refuse to believe that it gets up to the ozone layer.
@@jordizierz3395
If you're joking thats fine.
If not then here's how it can get to the ozone layer.
With gases things like to diffuse with each other over time. This will cause it even though it is SIGNIFICANTLY more dense than air to make it's way up. Of course it is incredibly tiny amounts but over time as it breaks down the concentration gets lower so more gets pulled up.
I love how the cylinder just immediately started moaning about having to do work as soon as you put the dry ice on it ;)
"Help this thing is on fire how will we ever put it out?"
"Like just make the air like heavy AF bro"
I say *don't* breathe it in. We need you Cody, we all need you...
we really do...
3:45 I thought that was cody being like "eeeeeh"
Same
I’ve watched this video a couple times now. I love that candle demonstration!
That candle bit was awesome
The fire square is to science as the Parker square is to math.
Yeah you don't want to breathe halon. It was popular in places like telephone exchanges and factories back in the seventies. I worked for British Leyland and if there was a fire we had three minutes to get out before the halon came on automatically. Not very nice stuff but good for putting out fires and people.
ehehehehe putting out people hehehehe
Awesome video - love the "river" of Halon gas putting out the candles :)
Loved the candle track!
That sound as fun as inhaling Cl2
The notification cured my depression for a few minutes
same
Not mine.
Exercise is a powerful tool against depression. Get out and take a walk after the video! : )
+Pusalieth You said a mouthful buddy. Good stuff.
Pusalieth The only role we have on this planet is to reproduce and that involves sex.
I have that exact fire extinguisher and now I finally know what to do with it. Thanks Cody!
i watch these mainly too see how much fun he is having and his laugh :)
Cody,
Back in 1984 I was working for the coal mining division of BP/Sohio. We were building a D. P. Center in Lexington, KY. As part of the build out we were to install and test discharge a Halon fire suppression system. (Note: This was well before Halon production was outlawed. It was also cheap enough that insurance companies would regularly require this.) We discharged the system as we stood around in the computer room singing "Barbara Anne" in very deep voices.
As far as I can tell, there were no ill effects.
Nothing wrong with me with me with me with me....
Halon kills, there was experiments on rats and a dog, the rats died and the dog had severe liver damage. We dont want cody doing breathing this in.
The halon isn't the problem. The halon being old is the problem
@@mihitm Ahh... Now *THAT* makes sense. I could see some of the age-decomposition products being phosgene and related compounds. Good catch.
that shirt.
Sadly it's getting to be so true it's scary. Pretty soon it will be against the law to say that women don't have penises.
+Stannis Baratheon Ok, what other basic biological or scientific fact would you rather I point out is becoming taboo to say? There are plenty.
The Triggerati Well, some people are taking climate science as a matter of opinion, not a matter of fact. The climate facts are very solid, and it is only "how much we are hurting the planet" that is left to debate. The climate is a huge system with lots of feedback systems, and predicting what happens when the climate is put in a position never seen before is very, very hard to do accurately - but everything is still pointing the wrong way.
The Triggerati well there's always climate change. Which has way more denialist than the fact that women's don't have penises
So glad to have you as one of my science teachers, Cody!
The candle experiment was very cool!
If it is so heavy, it would never reach the ozone layer right/
Diffusion
That's not how gasses work. They diffuse, and so it will move up, albeit slowly compared to lighter gasses.
Whoosh
Just put a net on top of it. It'll catch all the escaping halon
I'm guessing once it disperses like most gasses do it wont be quite as dense and therefore able to float on the other gasses in our atmosphere. Not entirely sure though so I'd love to know the real answer.
I work with removing old halon fire systems not advised inhaling it we have to wear full hazmat suits when discharging thousands of litres of this in to our recovery tanks
It's some crazy experiment. I like the candles being distinguished. Almost like a ghost trick.....
Excellent video cody, keep up good work sir.
"Do science while its still legal"
XD
How does Halon interact with the ozone layer if it's so dense
How does sugar interact with your tongue if it's denser than water?
Philip Polkovnikov it's directly touching your toungue
When I'm drinking soda there is no sugar directly touching my tongue. I prefer soda that doesn't have solid aggregates in it. Try it again, it's not that hard.
Philip Polkovnikov that’s not really a fair comparison. He is asking why something denser than air that sinks to the floor would be able to interact with something on the edge of space.
The halon doesn't interact directly with the ozone layer. It's broken down by sunlight, and the bromine ions this produces are the actual ozone-depleting agent.
Things like Halon flowing like a liquid over candles makes me so happy. Thanks you much.
Watched this after doing my final Peridoic table test in honors physical Sci. I had my periodic table with me. I highly recommend watching his vids with one. It helps!
Would turning the fire extinguisher upside down cause the liquid to transfer first, or would it all even out in the end?
Michael Steeves there's a tube running to the bottom of the fire extinguisher
It has a dip tube, so its like its turned upside down already.
Ye, I was thinking couldn't you have simply turned the extinguisher upside down over the other bottle with the pipe and simply poured it in?
Amerex’s (Company who produces said fire extinguishers) only model without a downtube is the co2 units
Fun fact, that stuff has 10 thousand times the opacity to infrared as carbon dioxide. The greenhouse effect to be caused by the little bit you have there is equivalent to all the carbon dioxide that is absorbed by 100 average trees over their entire lifetimes.
10 000 by weight or moles?
medexamtoolsdotcom
Pass me my phone, I need to call BS
You got any numbers to back up that statement?
i love that candle part that was pretty dope
I used to work on mainframes and the machine room raised floor had halon extinguishers under it. We were told that if it went off we should duck for cover since floor tiles near the nozzles would get blown into the air, but after the initial release just calmly walk out. They said that a bit of breathing it would be completely harmless. I'm curious to see if it's true. Keep researching!
Would be cool if you could make all of these heavy gases visible with schlieren photography while they put out a candle
Omg I have been looking for the word schlieren! None of my chemist friends knew what I was talking about, I was starting to think I made the word up! Thanks mang
Skeets McGrew no worries ;) it‘s german for streaks
Yes, burn the fire extinguisher!
@5:15 Blow torching a fire extinguisher. This is the quality content I subscribed for.
That was awesome, thanks Cody!
Cody get an old Lawnmower engine or something and dump Halon and all kinds of other gas's into the intake while it's running see if the gas makes it "Hydrolock" kind of like if you poured water into the cylinder.
It wouldn't, halon is still a gas and therefore compressible.
Its a compressible gas.
Darren Curry co2 is used to stop engines
Joe dirt Yes... by starving them of oxygen. Combustion requires oxygen.
Darren Curry one phrase: steochiometric (air/fuel) ratio. with a denser gas you'll have 'more air' in the mix than with normal air meaning the engine will run lean-er because not enough fuel is being combusted.
imagine what farting halon could sound like
inaudible bass?
Slap slap slap slap.
Halon gas is well known for extinguishing fires.
It is also great at extinguishing people.
Great video Cody!! I really enjoyed this one.
Filling a CO2 tank with CF2ClBr, and cooling the CO2 tank with CO2, but not filling it with CO2.
CO Teased
Could you attempt frobscottle with Halon?
Not a chance. Still too light.
You could attempt it
But you would fail
one of the most worth of watching channels nowdays
Seeing you poor gas from a jar and float a boat on "nothing" gave me shills. Literally one of the coolest things I have ever seen! People think helium is cool; heavy gasses are so much more. Bravo sir,.
Don't breathe it there's something called BCF sudden death syndrome
Resident Evil style
would breathing halon make your voice even deeper than xenon??
It should, but it might also make me dead. From all the information people have sent me today it looks like halon itself isnt the problem but the phosgene and other chemicials it has broken down into over time. And since the halon does smell a bit like moldy hay I can confirm.
Where does the oxygen come from to make the phosgene?
it would. but it would kill you.
Use a horned instrument to test. The note should decrease.
Also HALON is highly toxic advise against inhalation. In the US navy we're always told to leave when halon is released and given a time before a compartment is sealed when halon is released.
Doc Lock Why is halon released on ships? Fire suppression system?
the candle trick was really cool. super interesting video
As always, I love the video, bro. I would like to know where you got your t-shirt though, that's just awesome! :D Keep it up man!
