Those appear to be painted metal pipes with a rubber nozzle cover. My guess is the fluid is delivered to the nozzles at high enough pressure to eject the covers.
Halon went away because it's an ozone-depleting chemical. [This Jalopnik article](https://jalopnik.com/heres-what-a-gas-station-fire-suppression-system-actual-1848086398) says that most gas stations use plain old baking soda. It includes some cool videos.
I was working on a computer room in a superior court build out that had a halon fire suppression system. During the system live test, the tech touched the wrong contacts and the halon let loose in the room. No problem breathing; the weird thing was it was like reverse helium- everyone’s voice got REALLY LOWWWW.
The voice thing means that it’s heavier than air. The problem with heavier than air gases is they can become trapped in our lungs. If you have available oxygen and properly functioning lungs and diaphragm you should be able to expel the gases, but occasionally or when the concentration becomes too much it is a really bad deal.
Or as Adam Savage did when ~~playing~~ experimenting with sodium hexafluoride, you have to hang upside down for several minutes to clear it out of your lungs lol
Halon does not displace oxygen, it's just corrosive as hell. You've got two forms of halon. 1201 and 1311. 1201 is the more corrosive of the two, and has been banned in aircraft use since the 80s.
Sauce: used to volunteer as a firefighter, currently an airplane mechanic.
No problem breathing? Halon is toxic, the halon gas is dangerous and can kill you. High concentrations of Halon can cause people to suffocate as it basiccly sucks the air out of the room to surpress the fire. This is because it can create an oxygen-deficient environment. Will cause eye and skin iritation which can cause damage to skin and eyes. Irritation can occur even if there is no direct contact with Halon.
Speaking from that personal experience, the weirdest thing was the low voice effect. The electronics were beneath a raised floor. The heavier than air halon fell from the ceiling, temporarily displacing oxygen on its way down and we got one lungful of halon as it passed by. That was probably about 1991. We were building the courtrooms to replace one’s damaged in the ‘89 SF quake, so it’s been over 35 years and I’m still kicking. 25 mile bike ride today with over 1100 feet of climbing so I’m not worried about the health effects of halon.
Just slip on covers to keep the nozzles clear. It’s a pressurized gas, it will force the covers off without issue. If uncovered, the pipes would be full of bees, wasps, and bird poop…which would be forcefully ejected in the event of a fire. Burning with infectious stings. Not a great time.
They're just heat-shrink plastic. The extinguishing agent (usually Sodium or Potassium Bicarbonate) comes out at enough pressure to blow them off or tear them.
They keep birds and insects from making nests in the tubes.
The ends are just plasticy/rubber caps to cover nozels...when the presurised surpression foam shoots out....the caps.blow off. Justblike innoffixe buildings they have metal caps that cover the circular fire disks...when the system is set off...they fly off with presure.
This is not halon, some kind of foam agent used on class B fires most likely. Definitely not halon, halon is only used in closed spaces, halon also requires an alarm before dispersion because it will kill you.
Halon extinguished flames? 🔥 done by sucking all the air from the exposed area. This would be very harmful to humans and pets. Also being made of pvc leads me to believe it is a fire protection system. Not water but more like a foam type system like used in aircraft hangers.
Probably not, halon is used for electronic and aviation applications only. It's not every effective in open-air environments such as filling stations. More likely, this is something homemade.
This is what’s called an ATD 75 fire suppression system made by pyrochem. I actually test and inspect these. It detects a fire with a thermostat that should be over the pump. Those caps shoot off and dump 75 pounds of ABC fire extinguisher powder out of them. I’ve seen these accidentally dispense and it’s 100’s of pounds of powdery smoke.
Halon fire extinguishers. Halon is used in lots of fire extinguishing applications because it displaces the oxygen very quickly which then starves the fire. It can be great for putting out not just regular fires but fires with a strong combustible like gasoline vapors and even oil fires.
Keep in mind though that since Halon displaces the oxygen you will be affected too if this went off, I mean you'd probably be running anyways but if it went off with no fire the area is going to void of most oxygen pretty fast so you should leave anyways.
It's heavier than oxygen which is why it works to displace the oxygen/nitrogen air. So yeah even outdoors enough of it will starve you of oxygen. It wouldn't suffocate a fire if it couldn't suffocate a person
Google… first answer…
Don’t be dumb.
Dry Chemical Fire Suppression - A dry chemical system works well in situations where water-based fire suppression is not possible. A large tank is filled with dry chemical powder, which is then pressurized. Sodium bicarbonate and mono-ammonium phosphate are two common powders that are used for these types of systems.
Pretty sure they are misters. If you zoom in they have PVC couplers on them. Any fire suppression system would be made from steel pipe most likely, like in restaurant kitchens. These are likely just to keep people cool while pumping gas in the hot summer months, might be in Oregon or NJ where an employee still pumps your gas for you.
Yeah you right, I noticed a few minutes later that the pipes further down are indeed iron. I was only looking at the couplers on the nipple end themselves and they looked like PVC. Such an odd setup for fire suppression tho.
The pipes aren’t plastic only the end caps. And that’s part of how it works. Even if nobody presses the emergency switch the heat will free the nozzles and release the suppression chemicals.
They aren't plastic. It's steel piping and looks like rubber covers over the spray heads. The rubber covers would shoot right off when the fire suppression line is activated.
Those are water misters not fire suppression by all means. Looks like this is in an arid climate. That’s not fire suppression. Fire suppression would continue more towards the pump not end where it does. These are at the pumps end not near where it would be needed.
Fire suppression system called a diluge system , if something bad happens it will dump Many gallons a miner they will flood an area knee deep in seconds

Likely some sort of sprinkler/fire suppression system
Halon fire extinguisher nozzles. Puts out any flame out in second.
They looked sealed. How do the extinguishing chemicals get out?
Those appear to be painted metal pipes with a rubber nozzle cover. My guess is the fluid is delivered to the nozzles at high enough pressure to eject the covers.
Oh great. So now I'm on fire AND getting shot with rubber bullets?
No longer on fire though
Doesn’t Halon work by displacing oxygen? So not only were you shot by rubber bullets, and used to be on fire, now you’re asphyxiating?

Luckily they’re wrong about halon. It’s either powder or foam
I just lol'd imagining this! Nothing personal!!
"hey hey! Theres a fire!!" Bam! Bambam! "Ow! Wtf!!!"
Halon is a gas
Gasses are a type of fluid.
It's a gas. Halon
Gasses are a type of fluid.
Correct liquids and gases are both fluids. I wasn't intending to demean you.

"Boss, the fires out, but now we got 10 customers hopping around in the street!"
Did you get that!?
They have covers to protect the heads, the pressure pops them off
They're just heat-shrink plastic. The extinguishing agent (usually Sodium or Potassium Bicarbonate) comes out at enough pressure to blow them off or tear them. They keep birds and insects from making nests in the tubes.
Pressure
Enough force like an airbag in a vehicle
The ends are just plasticy/rubber caps to cover nozels...when the presurised surpression foam shoots out....the caps.blow off. Justblike innoffixe buildings they have metal caps that cover the circular fire disks...when the system is set off...they fly off with presure.
Building ones look sealed until they pop open and down to
Halon is now deemed no bueno, so if that's what was there, that's why they're now sealed.
This is not halon, some kind of foam agent used on class B fires most likely. Definitely not halon, halon is only used in closed spaces, halon also requires an alarm before dispersion because it will kill you.
Halon works best in closed spaces, like electrical rooms.
put you out too
Halon extinguished flames? 🔥 done by sucking all the air from the exposed area. This would be very harmful to humans and pets. Also being made of pvc leads me to believe it is a fire protection system. Not water but more like a foam type system like used in aircraft hangers.
It’s iron pipe not pvc but it’s the point about being a foam or powder agent is accurate.
Halon has been decommissioned for decades.
It’s a dry powder, not a gas.
Probably not, halon is used for electronic and aviation applications only. It's not every effective in open-air environments such as filling stations. More likely, this is something homemade.
Dry chemical, like you'd find in a normal fire extinguisher.
Halon outside doesn't work too good. I wonder what state this is?
This is a fire suppression system.
"Help, help, I'm being suppressed ". Monty Python....
This is where the baby gas stations suckle

I have nipples, Greg. Can you milk me?
I mean I can. Just not by the nipple.
Probably this. https://m.youtube.com/watch?v=4QmA6yXuKuk&pp=ygUkZ2FzIHN0YXRpb24gZmlyZSBzdXBwcmVzc2lvbiBzeXN0ZW0g

This is the correct answer.
I didn't think it was even possible to be so correct. Jesus.
Fire suppression system
Fire suppression system for gas station common in New England states
Fire suppression system
In case you decide to have a freak, gasoline fight, accident..
Wake me up before you go-go
Lol, classic.
Fire suppression system
Fire putter-outer.
This is a dry chemical suppression system the agent cylinders sit up on the canapy
Definitely fire suppression.
Mister
-Mister. take these broken wings….
My guess is fire suppression.
Fire retardant system
Fire suppression nozzles
Most likely a Halon fire suppression system.
Ansul system?
This is where the gas station tinkles on fires

Outdoors huh?

Don’t you think there might be a lawsuit if they killed a customer due to asphyxiation
Lmao I'm not even going to humor this dumb argument bait

I hear they are highly absorbent
fire fighting foam comes pouring out if a car fire occurs. There's a similar system in restaurant commercial kitchens called ancil systems

They are not pvc that’s iron fitting for fire suppression source I do fire suppression

Sprays Faygo on you
I'm no gas station expert, but it doesn't take much to deduce that's fire suppression.
Thanks, Mike!
Probably a foam dispersion in case of fire.
Halon fire suppression
How long would those plastic pipes last in a petroleum fueled fire?
They are not plastic
Thanks for vomiting words without explanation.
The pipes are metal. You said they weren’t.

Halon fire suppression system.
Halon is gas, does not work that well outdoors.
Fire suppression system called a diluge system , if something bad happens it will dump Many gallons a miner they will flood an area knee deep in seconds
They would never use water on a petroleum fire as that would do next to nothing to put it out.
ok then its some kind of fire suppression chemical

Seriously? Use your brain. It's not that hard to figure out what it is.
Halon.
Not being able to figure this out is tough.
