@@henrylo6773if a plane catches fire, even with a fire suppression system, it is a write-off. No. This is to make sure it doesn't kill people and set the entire airport on fire.
About 35 years ago I was working in a hangar at a UK airport when the foam system suddenly deployed accidentally. In a few minutes we had 6 feet of foam on the floor before someone hit the override switch to shut it off. The problem was we had a B747 in there undergoing very heavy maintenance. The foam system included foam canons that shot the foam up into the air right over the aircraft parked in the hangar. The foam got in everywhere, it took ages to clean it out. It happened again at another company I works for, but this time I was off shift and only saw a video. But there was an Airbus A320 in the hangar with all the doors open at the time. Again it took ages to clean it out! Quite spectacular when it goes off.
For anyone who doesn't know that is AFFF (aqueous film-forming foam) 94% water 6% concentrated soap. It main purpose is putting out class B fires (jet fuel and other flammable liquids. Edit: Yes the term "soap" is a touch misleading (years ago that was how it was explained to me) I am not that familiar with the science of how AFFF works just the concept and components of the system. Also yes AFFF is corrosive however it is not going to be used unless there is a lot of fire in saying this a circuit board on the fritz or rust is going to be the least of someone's problems.
@@howardsimpson489yeah from what I've heard not only is this stuff kinda toxic but it also corrodes the aircraft components making and any airframe smothered in the stuff either a total loss or at best very expensive to repair?
I'm installing one for Gulfstream in Arizona right now. They are no longer using AFFF foam. To many cancer causing agents were found in that stuff. I have a battalion chief firefighter dead because of it and another fire truck engineer going through cancer from it
@@ahmaddanielazmi1339 it's not that corrosive however in it's concentrated form for long-term storage it does have to be stored in a copper nickel container and also a little bit of Rusty nuts and bolts is way better than a plane or multiple planes burning down.
In case anyone is wondering it takes two flame detectors to set off the foam. The men you see running set off one on the far end of the hangar then set off one on the near side. That is why it takes so long.
@@jessicahelther99 In an actual fire they probably go off automatically and more or less simultaneously when they both sense above a certain temperature, manual activation during a test generally takes longer for most systems and has more steps to keep idiots from accidentally setting it off.
Worth noting is the contractors deliver the foam in very useful blue poly barrels they don't need afterwards so if you ask nicely and offer to take them all they may give them to you. If you slice off the bottom of one and the top from another (a cutting disk on an angle grinder, a recip saw or circular saw works well) you now have a handy container that seals so well against moisture you may have to pry it apart. Rinse out the foam residue of course but that's biodegradable. I used mine for outdoor parts storage and I've left engine parts outdoors for over fifteen years without moisture intrusion. They're great for livestock feed and much more.
Dealt with similar systems while I was in the navy. We were going through an inspection cycle and part of the inspection was to properly tag out or secure certain portions of the system so it would not actually release and then go and push the activation buttons to make sure that the system started properly but since we secured the system to recirculate it would not dump. The chief in charge of the inspection wasn’t happy when the inspector said, it isn’t tagged out properly, tag it out properly and after lunch we will resume. After the inspector left for lunch the chief to prove they were right went and pushed the button and from what I heard said “don’t tell me I don’t know what I’m doing” while pushing the button. Well the inspector was correct and it released all over like 3 super hornets all with their cockpits open and 1 of which was fully opened up for an inspection and like 2 sea hawks. So the aviation maintenance has to basically go through and completely recertify all those birds for flight from my understanding. But hey. Don’t tell them they don’t know how to do their job…
Militious Compliance, the armed forces version of malicious compliance. Also known as "don't push your CO out of the way to fall on a sword on their behalf".
I work in a airplane hangar where we get C-17s , C-130s, and C-5s and we have this as well. It takes 5 minutes to fill up the entire hangar from floor to roof, wall to wall.
The fun part is that without the active ingredient (the foam mixture) you would be standing under a misting rain wondering how it could ever put out a fire.
@@nearbygamerfanable it is corrosive though. Any aircraft caught in it would have to be immediately cleaned thuroughly and most of the sensitive components would have to be replaced.
Foams used for fire fighting are almost always very safe for the environment. One of my neighboring departments fills up a field in a park about a foot deep with foam every year for kids to play in. So yeah wash it down the drain most likely
Me: Never ever ever ever searched for anything Aircraft hanger related. RU-vid: This guy looks like he needs a 2 year old video on Aircraft hangers. Update: This is the second time i got this in my recommended even after i watched it. RU-vid really has a thing for Aircraft hangers.
That's because RU-vid is changing their system to reccomend things that are 'clickbaity' like this as opposed to videos that provide information that goes against the establishment narrative. Basically they're dumbing it down.... and dumbing the users down.
That is one of the coolest videos I have ever seen. Thank goodness there was not a real fire. I hope no fire of any kind irrupt‘s anywhere like that, so it is a good thing that the foam suppression System did its job.
Reminds me of when I worked in a place with a server room. That same alarm tone, but if you heard it and you were inside, you had 30 seconds to exit before the doors locked and the Halon displaced all the breathable atmosphere in the room.
That’s not how Halon works, it breaks the chemical reaction of a fire. You can easily look it up. The amazing part is that it stops the thermal energy, a cool surface remains.
They actually silence themselves in favor of those faint “hangar doors are in motion” alarms you can hear while the doors are closing. Then they start blasting again once the doors close, and when they do, that’s your final 60-second warning to run like hell if you haven’t already, ‘cause the Foampocalypse is coming…
Ckc dillpickle The point of foam is to suppress the fire. Water will not work on chemical nor aircraft fires and will actually make the fire worse. In firefighting foam The surfactants used must produce foam in concentration of less than 1%. Other components of fire-retardant foams are organic solvents (e.g., trimethyl-trimethylene glycol and hexylene glycol), foam stabilizers (e.g., lauryl alcohol), and corrosion inhibitors. Using water or water based products will worsen a chemical fire Edit: i took out the joke because people thought i was being serious but it all good Edit: btw i took that from google so... stop with the replied
BigJaZz Music ok edgelord calm down. He said probably, he didn’t exactly know and just thought that it’s water based, which it is. Nobody cares about what you stated but at the very least don’t ‘casually’ insult someone.
Seriously Mason Me: I use RU-vid for at least 90% music and the rest of it on cars. RU-vid: Are you sure? I have something completely irrelevant that I need to show you, like now!
We actually had these deploy at an air park I work at, they have small offices inside the hangar and the employee thought it was a drill and finished sending off some last minute emails. By the time he was done the entire hangar was filled and he ended up running into the foam and suffocated to death.
I got to experience this first hand when I was in the Air Force, something malfunctioned and the system went off, foam was everywhere covering roads hundreds of feet away from the hangar
You leave the hanger , mission impossible music begins to play, The Roomba sends a distress signal thousands of Roomba’s appear jumping out the back of a cargo plane with tiny Roomba sized parachutes, they’re lined in formation they go in.. some have their sensors blinded, others get their brushes clogged, but they solider on cleaning with robotic efficacy. In minutes the foam is cleaned up. The mopping Roomba’s are sent in the floor sparklers, Winbots rappel from the ceiling and clean the windows satisfied in there cleaning job the Roomba’s beep in delight. The celebratory beeps gets your attention. Mission impossible music stops You open the door as you do the Roomba’s have disappeared like ninjas. You look in awe as the only Roomba left goes back to its charger.
If it’s anything like what’s in a fire extinguisher I’m pretty sure it would make you suffocate to death, tho I could be entirely off on this and I’m too lazy to fact check but whatever
@@lonelegend4845 I gas mask only works when areas are ventilated meaning theres air. Wearing that will kill you even faster. It doesnt just filter air through the foam if that's what you're thinking
I'm not sure what kind of foam that is, but I am impressed by the rate of expansion, force through pipes, and the ability to fill about one third one of third of the contained space in 2 and a half minutes. Good stuff.
Older types of high-expansion foam used perfluorooctane sulfate and perfluorooctanoic acid as key components in the AAAF fire suppression systems. These are both types of polyfluoroalkyls, or PFAs, which are the stuff we make nonstick pans out of. They can certainly be environmentally hazardous, so the air force has developed more environmentally friendly alternatives and has so far gradually been replacing them since 2015. As to whether it's carcinogenic or not I'm not sure, but I think some studies from fairly recently seem to point to that being true. I can't tell what foam they're using here though
@@inverse2k1 Not only is it toxic but is known as a permanent toxin. It does not break down in nature and ends up too diluted to be detoxed. In NZ we have ground water and runoff streams so contaminated after runway fire foam drills that the surrounding houses have had to be evacuated. Not quite as bad as agent orange.
@@inverse2k1I would take an increased risk of cancer or a few tens of thousands of dollars in cleanup, over burning to death horribly or potentially losing hundreds of thousands to literal MILLIONS of dollars by having my plane and hangar involuntarily reforged into a giant piece of slag.
I’m in the USAF and they warn us about these as we have one in each of our hangers. That foam is deadly to us. It sucks the oxygen out of the air and if you get caught in it your done for. So we ever hear those sirens, drop everything and run
@@windy8872 it's not just foam, this stuff sucks oxygen out of the air to kill the fires. We had two people die once because they accidentally set the alarm off for the suppression system
@Daniel Hollingsworth Daniel I meant nothing disrespectful but the "I mean ok👌" I fully agree it is factual I guess I should have clarified I have much love for you as a fellow human and I wish the best for you peace and love dawg I ain't trying to get in no pity youtube comment beef✌❤
When I worked for the US Marshalls air operations division in OKC I accidentally set off the foam fire supression by hitting it with the power cable when I was putting it back on the hook which was about 10 in away from the fire handle on the wall. I had only worked there about 1 to 2 weeks. I felt awful.
We have these huge annual drum and base party where they flood the dancefloor wit this stuff, I can tell you its huge fun, but diving head first into this wouldn't end well xp
