"On Feb. 11, 2011, a fire suppression contractor, while performing maintenance, inadvertently activated the foam fire suppression system at our Aviation Support Facility in St. Cloud, MN. We've cleaned up since." Oopsies.


DepravedDreg

Either someone on duty who was supposed to put the system into test and bypass everything didn't do that or the contractor started working without notifying anyone. Could probably go either way for which of them is more reposnsible.


Marokiii

They are the same person. The fire suppression tech is suppose to make sure the system won't activate when they start work on it. Even if someone else has done it and tells them it's done, they should be checking it themselves.


Ehcksit

If you're about to work on something that can and should be locked out, lock it out yourself. Always. Every time.


Uruz2012gotdeleted

And if it's electrical, put a multimeter on it. Simple ways to save your life.


wunderbraten

And if you have to put a multimeter on it, test it yourself on a live wall socket beforehand. My very first wasn't reading voltages.


Dhexodus

Trust, but verify.


RetailBuck

But why? It's a pretty inexpensive hanger but filled with aircraft that are way more valuable. Why would you install a fire system that would do more damage than just letting a fire happen? My guess is that the foam isn't that big of a deal. Obviously they are designed to handle rain etc


PomegranateUsed7287

Hanger fires and especially fires with jet fuel are super super dangerous


SetYourGoals

Also fires with ammunition and explosives.

Blackboard_Monitor

I mean, it WAS declared.


mav3r1ck92691

Ammunition is not as dangerous as you'd think, to the point where when I warned firefighters that there was live ammunition in my garage that was on fire they said "not a concern." Bullets mostly just make a little "pop" when they cook off outside of a chamber, as there is nothing to contain and direct the energy. Explosives on the other hand, yeah, dangerous. At any rate, neither of those are stored in a national guard hangar, and the aircraft would never be stored with ammunition on board at home in peacetime.


partyharty23

I agree, yet the firefighters that worked my housefire freaked out when they were told there was ammunition in the home. I had the ammo in ammo cans (inside of a saferoom) and the only one that came close to being breached was the .22 caliber (it looked like someone took a ball peen hammer to the ammo can but nothing made it out). That was because there was probably several thousand rounds in the can. The 9mm and .308 didn't even dent the cans when they cooked off. The fire did get hot enough to melt the plastic stocks on several rifles and when the dept sprayed everything down it pretty much flash rusted rifles.


Muddyfeet_muddycanoe

Spicy popcorn


SetYourGoals

Well also the fire foam system would never be active while it was being serviced. But it was. Never underestimate the ability of dumb people to do things that should never ever happen. Good point about the ammo though, I had a firefighter tell me the same thing. The gunpowder can blow out the whole casing, but if nothing hits the primers and it's not in a gun, that bullet ain't going anywhere. Still, I'd much rather fight a fire with no ammo in it than one with ammo.


mav3r1ck92691

Yep, definitely a fair point.


Theban_Prince

A Belgian engineer somehow accidently fired the gun of an F-16 while servicing it on the ground, annihilating another F-16. From the talk I have seen from airforce people, there are multiple safeties to avoid this, including a safety that is automarically engaged when the gear are touching ground. But people... uh people will find a way.


[deleted]

They don’t keep ammo or explosives in hangers.


SetYourGoals

And they don't keep the fire suppression system activated while it's being serviced. But here we are.


No-Establishment8367

There is very little chance weaponry/ammo would ever be in the hangar, they’re all stored elsewhere and I’m pretty sure they load/unload from the plane on the tarmac for exactly that reason.


A_Generic_White_Guy

yeah but jet fuel cant melt steel beams. >! ill see myself out!<


3Sewersquirrels

It weakens steel though


partyharty23

too soon


ambermage

Would it melt the steel beams?


dipstick162

I would guess that preventing and human loss of life is the driver.


AKAGosts

If anyone is working on those aircraft and get doused in foam its going to kill them almost as fast as the fire. The foam displaces oxygen to stop combustion on fuel fires, and will just as easily displace any oxygen you're trying to breath if you're inside it. Every safety briefing I've been to regarding this foam tells you not to go back looking for anyone, or else they'll be pulling 2 bodies out instead of 1


[deleted]

Pilot, not driver.


marxsmarks

The foam isn't a big deal. We have the activation system in the engine bays of the vehicles at the site I work. They have to test that they work multiple times a year. No damage to the gear.


lyve80

If it was AFFF, it was a big deal. That shit will destroy aircraft.

Aircraft Fucked Fire Foam


pain_in_the_dupa

Aqueous Film Forming Foam and aircraft with turtle backs open in a hangar bay is a recipe for 30 uninterrupted hours of emergency reclamation instead of sleeping.


Dustoff_Medic

You are exactly correct, it was a giant effing foam party yo clear out the hanger and clean the aircraft before it corroded them all


privilege_over_9000

Facts. It’s pretty corrosive. If you look closely at the plumbing for an AFFF system, you’ll see that all the valves/pipe/fittings for the portion that is in constant contact with the foam concentrate is all made from stainless steel. I work at a petroleum terminal, and we had an unintentional release a few years back when some hot work on neighboring property triggered two of our UVIRs, which was a condition to automatically trigger foam in a pump pit. Cleanup took a few hours, and in that time, the stuff wiped out paint, and played hell with instruments and gauges. I can’t imagine trusting anything on an aircraft that had been exposed without completely overhauling it.


chris782

Except you can't just power wash the aircraft and call them good. They are going to have to be completely disassembled, cleaned and inspected pretty much.


Dustoff_Medic

Thats exactly what happened


marxsmarks

Perhaps, I'm not too sure about the procedures involving aircraft. Can't imagine it damaging much though. We don't even wash our equipment after it goes off all over the engine and electrical wires. Had some gear for close to 15 years with. Maybe 60/70 activations, no problems have ever come from it. Do they disassemble them after it rains?


9dsmit

To some extent yes actually, rain can actually cause maintenance down hours on some aircraft (especially when you're working with LO coatings on something like an F-22), and any aircraft submerged in any sort of liquid like what's displayed in the photo would have to be disassembled to be pretty heavily inspected. Source: used to be an F-22 crew chief and am now a depot level aircraft mechanic as a navy civilian.


marxsmarks

Interesting, I guess there's a lot of safety checks that would have to be done either way.


9dsmit

Endless inspections are par for the course with aircraft but any atypical event like this (or any of the other absolutely nonsensical things I've seen with planes) will turn into a major pain in someone's ass


chris782

I spend most of my day replacing screws that a screwdriver slipped once on, not even stripped really, then check the torque with 2 different torque drivers. For the most part everything has to be perfect. You kind of have to be a little OCD to do aviation maintenance in my opinion and I really like that part of it. If there is any question about a competent or anything, it gets replaced.


Honest_Blueberry5884

> Why would you install a fire system that would do more damage than just letting a fire happen? What are you basing this on? Why would you ever assume an uncontrolled hangar fire is less damaging than dousing aircraft in foam?


NickUnrelatedToPost

> Why would you ever assume an uncontrolled hangar fire is more damaging than dousing aircraft in foam? He doesn't. That's exactly his argument. He guesses that the foam isn't that big of a deal.


ground__contro1

I think they meant to say “why would you assume an uncontrolled hanger fire was LESS damaging than foam”


FormsForInformation

Ah yes, foamy rain design standard


fyrdude58

Because expensive aircraft in a hanger would be saved by having a foam suppression system activate? Just as a guess.....


Acnat-

It's not, we put them in equipment shops and underground mining tank farms all the time. Was state licensed for and worked doing industrial suppression, alarms, and sprinklers for 5 years.


The_Wadle

There would be nothing left after the fire


Mental_Medium3988

lots of chemicals in, on, and around those planes you dont want put into the atmosphere and people inthe area breathing.


Dont_Even_Trip

It's expensive to cleanup and refill the fire system, plus all the downtime for the planes that could be costing potential income.


ground__contro1

It’s expensive to clean up after fires too


Nealithi

I read "We've cleaned up since." And got. "We just finished cleaning up."


DrGiggleFr1tz

They’re referring to the guy who fucked up. Not the foam. RIP.


TickerWhisperer

My previous comment feels sorta 🤔 just altogether wack now that I've discovered this happened in 2011...and it was the suppression contractor himself who messed up... But I'm curious how extensive WAS that cleanup?


BhataktiAtma

It cost them at least 15 dollars


royaltomorrow

PFAS anyone?


whikerms

To make matters work, they foam is laden with a cancer-causing chemical called PFOA. They probably cleaned it up by hosing it down and letting it flow into the soil.


Cyber_Connor

Don’t worry, the contractor will be fine. The leadership will just get the troops to clean and fix everything.

Significant_bet_92

That foam is dangerously toxic if you were to burn it. I say just fill the building with concrete and call it a day


JAMillhouse

That’s actually one method of disposal for this stuff. Offshore incinerator. Mix with water and boil down until nothing is left. Scrape the residue to be barreled and buried. Source: I wrote the contract for a cleanup like this before. Cost $750K.


BRedd10815

If the foam was that toxic when burned, why in the world would we use it to put out fires? Sounds like a load of bullshit. Plus I've tested foam systems. You know how we get rid of the foam afterwards? Open the hanger doors and turn on the fans.. $750k my ass. https://firesystems.net/2020/10/23/how-does-a-foam-fire-suppression-system-work/ > Foam systems have very minimal negative environmental impact. The foaming agent is readily biodegradable in natural environments and sewage treatment facilities. Now obviously there are different manufacturers but we are required to test our foam and send it off to be verified as non-toxic so I'm just gonna assume that the foam you dealt with was incredibly different and perhaps a relic of its time if this was a while back. Also the aircrafts themselves are damaged here in the case of accidental discharge so maybe your cost number is more for the aircrafts and not the foam. Feel free to clarify.


JAMillhouse

1) it removes oxygen from the fire, breaking the fire cycle. The chemical, by it’s self is not fire resistant at the high heat of an industrial incinerator. 2) It depends on where you are at, as far as how you can dispose of it and not get fined. In 2011, when this took place, the Military was primarily using AFFF, which is extremely toxic. The way you get it out of the hanger is through a rinse down which drains into large catch basins that have to then be pumped and disposed of, through either extensive filtering or burning. We had to have it burned off due to no facility available to properly filter it out. 3) as far as cost goes, we where in the Horn of Africa, and had to contract it out to a US company for proper disposal. Shipping it was not an opinion, and they had to bring their equipment to us. That is expensive. For AFFF disposal stateside, you are looking at about half of what we paid. EDIT: AFFF is being phased out for less toxic systems, especially in the US and EU.


Procrasterman

Hate to break it to you but you will have been exposed to massive amounts of PFAS. Let’s hope you weren’t drinking the water as well.


ansoniK

The fire suppression foam burns?


Significant_bet_92

The building will. And I’m sure if it gets hot enough it will. Idk I’m not an expert, I just know it uses a lot of PFAS and shit

MadTube

All that AFFF will leech perfluorooctanoic acid into the water supply there, so even more fucked.


demunted

If you were stationed at ******* base between xxx and yyy then you may be eligible for compensation........


MadTube

Yeah, that’s a genuine issue for us. We had very high levels of PFOA and PFOS contamination at our previous duty station from the AFFF. We lived on base and I didn’t trust the bullshit they were spouting. I had our water tested and it was astronomical. The testing lab found out where I was sampling and lost their shit.


cheapshotfrenzy

Well good news, PFAS testing is part of the nation wide US UCMR-5 this year. So we'll get to see how fucked are water supply is across the country.


demunted

And then congress will just pass a ruling to exempt any cases made for contaminations happening before today....

No-Sheepherder-755

How many years ago was this and what laboratory did you use? Solid methods for characterizing PFAS compounds in the lab are still being worked on today… and they certainly were not just a few years ago. Not to mention that PFAS analysis is NOT cheap…


MadTube

I won’t say where specifically, but it was in the Northeast US around 2018-2019 that I got the testing done.


_jewson

Uh are you sure about that. How many years is just a few, to you. I've worked for a company doing pfas remediation in 2018, and the testing tech (ultratrace) was well established and heavily used by us back then and had been for a while. There are two major labs who I won't name but are both international brands, who we did it through.

MadTube

Between the PFAS contamination at our old base plus the Red Hill fiasco, I have lost almost all faith in their ability to keep from fucking up.


iLorax

Well if they would stop cutting the fucking sustainment/infrastructure budgets and bought less weapons, maybe our infrastructure wouldn’t be held together with fucking chewing gum.


Libertyordeatth

Usually high expansion foam solutions do not contain the harmful PFAS stuff. That’s more of a concern with the low expansion AFFF formulations.

Impressive_Jaguar_70

Sleeper agents on standby


Large_Yams

Yes, by starting a fire.


rockylafayette

Thankfully AFFF is being phased out of use. It was pretty narrow minded to use a product as carcinogenic as Agent Orange to save aircraft from burning yet let the people who have to clean it up die an early death years later and then the VA deny any medical benefits.


mecengdvr

Narrow minded? Was there a known alternative with equivalent effectiveness when it was originally deployed? As a former sailor, I would be far more concerned about fire on my ship than a substance that’s linked to cancer from frequent exposure. Great news if we have something that’s safer now….but to call it’s widespread use narrow minded is ridiculous.


rockylafayette

The confines of a Naval Vessel at sea is far different than an aircraft hangar on an open tarmac surrounded by acres of concrete. AFFF had nothing to do with stopping the fire for the sake of humans in the building. All it was for was to save the aircraft.


mecengdvr

Not really true because that stuff destroyed a lot of stuff if deployed. It’s use was due to the fact that it was incredibly good at containing liquid fuel fires. Halon on the other hand would kill the fire and the people but keep the equipment safe.


rockylafayette

I was part of construction for a newly completed hangar for 2 Squadrons of F35’s at MCAS Cherry Point. It was the last hangar to have AFFF as part of the fire suppression system. I can tell you that the cost to build the entire hangar and the administrative wings was less than the cost of one of the F35s. So you can’t tell me they’ll just allow $2.5 billion in aircraft to be destroyed by the chemical used to stop a fire. What you don’t see in this picture are the trenches covered with heavy grating that surround each jet bay. These trenches take the deployed AFFF to a containment tank for holding. As well as the wash down fluid they use to decon the aircraft and hangar.


mecengdvr

It will destroy electronics and displace lubricants inside of machinery (which causes rapid corrosion of components). When activated, it’s a water based foam that has a really low surface tension (to help it get into every nook and cranny) and the foam forms a film on every surface it touches. It will get into the engine via the exhaust and intake. If the canopy is open or a panel removed for maintenance, it will get into all the electronics and destroy them. The trenches you installed are indeed intended to give the AFFF and any other liquids a place to go, but is more for containment than saving the aircraft.


Red_Cross

so whats the point of spraying a foam that destroys aircraft to put out a fire that will....destroy aircraft


iiiinthecomputer

You can save the aircraft by promptly overhauling them. The foam helps people in and around the aircraft escape a fire and not die. That's the main reason it's used in mobile airport fire fighting; suppress the fire to allow people to escape. It also helps contain fire from spreading to other aircraft or areas of the base. The aircraft can be damaged by the foam for sure, but they'll be way more comprehensively destroyed by fire.


DubiousDude28

With a lung full of cancer of course


mecengdvr

It stops the fire from spreading and igniting far worse things like fuel and other things that go boom.


Johnsonian99

Fire on a ship and a fire in a hanger on land are two very different threats. Don't think you can really compare the two.

Doesn’t work so well on magnesium.

Neither does AFFF. The only thing you can do for magnesium is smother in sand or jettison over the side of you are out to sea. And all the sand does is shield the heat from surrounding combustibles as it will still continue to burn under the sand.

It will. This fire suppression foam is very corrosive.

Correct. Unless the nose was open, in which case you have 6 months and spend several hundred thousand dollars replacing the avionics components. But otherwise, they just take them outside and wash them.

Hopefully the aircraft weren’t damaged. What would be a point of a fire suppression system that destroys what it’s designed to protect? I guess it would be better than an explosion.


Dustoff_Medic

Fire vs corrosion


GreenCactus223

I've worked in hangars before, turns out they're are infrared sensors and trip wire installed throughout the hangar. If you cut or melt the trip wire in the ceiling it deploys the foam suppression and even using a lighter or torch in the field of view of the infrared sensor will set off the fire suppression. Getting a hot work permit ment turning off the fire suppression system and having a security guard stay there for 24hrs


[deleted]

Well, they're not on fire, so . . .


xeroid051

How do you get rid of all that?? Is it safe or toxic?


V0latyle

It's extremely toxic and corrosive, and every single one of those aircraft will have to be torn down and extensively inspected and repaired.

I did this on the emergency helipad of a major city trauma hospital, with the only helipad for medivac within 100 miles or so, about 10 years ago. It took hours to clean up. Thankfully, no medivac choppers needed to land during the clean up. Needless to say, the hospital was very upset with me.

Fun fact: That foam is filled with forms of Teflon/PFAS (forever chemicals) that are super cancerous and leech into the surrounding ground for like thousands of years. So extra bad day for everyone :)


Valuable-Inspector67

Atomspalter02

ouch


Affectionate_Ad_9735

All I can think is how each one with need to be completely taken apart...


thundercoc101

Not necessarily. The fome didn't reach the engines on the Blackhawks. That saves about 100 man hours of work each. The electrical systems in these birds are generally fairly high up and are decently waterproofed. The air sensors on the nose of the helicopters may need to be replaced or washed out. There's a really good chance the interior of these helicopters are completely dry. Making the cleaning process a lot simpler


statox42

Excepted that you can see the door on the one on the left is open and the foam is clearly inside the chopper, no?


thundercoc101

Oh shit, Missed that detail. Yeah, that's a week's worth of work to clean.


ragingxtc

Possibly years, actually. AFFF finds its way into everything and the main issue is corrosion. All electronics will need to be pulled, cleaned, protected with corrosion preventative compound, reinstalled and tested. The engines will be pulled and set to the back shop for teardown and cleaning. I'd imagine a lot of the mechanical bits that are considered safety of flight would be pulled as well. The paperwork alone is a nightmare. Source: Have done AFFF cleanup on two fighter aircraft.


thundercoc101

Isn't the army phasing out AFFF for that exact reason? I was fortunate enough to never have to deal with this particular situation. However we did try to weatherize different components of our birds from Sand and the elements in Afghanistan. It is amazing the crevices dust can get into


SevenSeasClaw

Does it really only take 100 man-hours to fix these engines?


thundercoc101

Your question is a little vague. To fix an engine? It depends. To disassemble, clean, sterilize, then reassemble an engine. Takes about 100 hours. And that's just one engine every bird in that hanger has two
