[@MichaelTurvey1979]

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.

[@PhillipBicknell]

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.

Ever read BOFH? Halon can kill, please don't breathe this!

[@rkirke1]

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! :)

[@Miata822]

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.

[@edgeeffect]

I used to breathe it all the time... had some MAD hallucinations but I'm still here, about 30 years later.

[@thedeviant]

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!

[@Tivy_]

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.

[@Waty8413]

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.

[@wimvanrenterghem5725]

So I’m genuinely curious, how does such a heavy gas get high enough into the atmosphere to cause ozone to break down?

[@Heptkaidekaphiliac]

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.

[@sokjeong-ho7033]

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"

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.

[@flysubcompact]

Got lucky with that one. I know that Amerex FE's use proprietary threads.

[@SeanBZA]

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.

[@IndieMarkus]

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.

[@jetison333]

IndieMarkus oooh that's an awesome idea actually

[@yk-et3un]

THIS NEEDS TO HAPPEN

[@RoaldFre]

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.

[@simongregory9453]

@@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

[@RoaldFre]

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.

Just that they are a lot more careful in servicing, and scavenge the gas out wherever possible because of cost.

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.

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?

[@besanit]

just guessing but is dense as a pure gas but then it mixes with the atmosphere and individual molecules can be carried up

[@TJStellmach]

The halon is just a source of bromine ions (when UV breaks it down). Those are what does the damage.

[@abdallatefnsour]

Halon is broken down to bromine ions by the uv rays from the sun the bromine ions deplate the Ozone

[@Killerspieler]

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 :)

[@Muonium1]

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.

[@MandrakeFernflower]

Would bubbling through a solution of NaOMe methoxylate the bromide? Might be a easy way to destroy the stuff

[@KainYusanagi]

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.

[@theCodyReeder]

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.

[@jamief415]

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.

Cody, maybe you could record your voice and then play the recording through a speaker submerged in the Halon? Would that work?

[@gesus44]

Probably not, but I like the angle you are working with.

[@skeetsmcgrew3282]

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

[@sinktroll4116]

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.

[@koori049]

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.

[@wizardryreviews1254]

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.

[@SpecialEDy]

I was in an AT&T server room when the Halon fire suppression system went off, they were working on it so the warning lights and sirens that give you time to evacuate didnt go off. It sounded like a string of blackcat fireworks going off, and I ran about 50 feet before the cloud of smoke descending from the ceiling engulfed me. It was so thick you wouldnt of seen your own hand in front of your face. Ran the last 50 feet in the last direction I saw the door, till I saw the glow of the door to the hallway. A shadow appeared, it was a fireman who literally grabbed me and threw into the hallway. 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?

[@scrimpton0160]

r77xxl wait what?

[@0xBADFECE5]

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.

[@lyckl_6609]

Lol

[@quint3ssent1a]

Scrimpton 01 flies probably died because halon displaced air and they're just suffocated, not because it's toxic.

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.

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!

I work in electrical distribution. We have rows of huge tanks filled with halon in the bottom of some industrial stations for fire suppression. We are trained that no matter what you are doing, holding a live wire whatever. If you hear that alarm go off you drop what you have and sprint for the stairs to get out of that basement. Once the alarm goes off you are seconds away from asphyxiation. I'm not sure if it works like carbon monoxide and attaches to your blood cells, but I'd still steer clear of inhalation of it.

Of course it is incredibly tiny amounts but over time as it breaks down the concentration gets lower so more gets pulled up.

We use Halon 1301 in our aircraft fire extinguishers. Upon exposure, expect reduced lung capacity for a few minutes to days. Left a couple of us coughing for around a week or so. I imagine 1211 will affect people in a similar manner. Limit exposure as "tunnel vision" sets in quick due to lack of oxygen and its something we're trained to notice before its too late.

[@cblamo]

I heard a story from an old instructor of mine who had a halon extinguisher go off while he was driving an APC. He got out fine, along with the rest of the crew. One of his mates sat down to have a smoke and just quietly died sitting up against the wall. I don't have any actual documentation to back it up, not do I know if its the same stuff you have, but I've heard a number of similar stories on the danger of halon.

[@Duckcraper]

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.

[@TJStellmach]

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.

[@isnak907]

It is a fire tetrahedron. The chemical reaction is the floor on which combustion stands. Halon while having some oxygen displacement and thermal capacity for flame cooling most productive fire fighting or atmospheric inerting it to interfere with the chain reaction of combustion. I work in an oil production facility where we use bromotrifloromethane to inert buildings in the event of a gas release or a separate system to fight a fire. 7% is what is used for inerting.

[@KJLCreations]

When I was Active Duty in the Coast Guard, one of the Cutters I was on had a Halon Fire Suppression System. Long story short, the seals broke and it discharged in the Engine Room where I was working. I inhaled quite a bit for a period of 2-3 minutes. It then fed into the turbos of the Main Diesel Engines which were sitting at 900-1100 degrees Fahrenheit. We were told that when Halon reaches its critical temperature (900 degrees Fahrenheit) it changes to Hydrogen Fluoride, or some type of compound that is highly erosive and toxic. I still feel the effects of this incident, and would suggest not to inhale it. Great channel, stay safe.

[@doubledarefan]

The fire square is to science as the Parker square is to math.

[@Forticus55]

Ok Cody. I have a question. How can something so heavy be a “potent” greenhouse gas? Wouldn’t such a heavy gas just displace the nitrogen, CO2 and oxygen at the surface?

[@Heptkaidekaphiliac]

Sad to see no one bothered to answer this. 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 accumulate in the atmosphere to absorb radiation. However, it does break down over time and so due to its short life in the atmosphere would only be a serious issue if the pollution was continuous, unlike with CO2. The ozone depletion is more serious.
