Fire extinguisher chat made me think of a problem that�s been bugging me for months, though I think I finally cracked the case.

In aviation we use Halon 1301 to put out engine fires. Every time the topic comes up someone or another will swear that it is safe and does not bind with free oxygen to smother the fire. This is reflected in nearly all industry documentation that I�ve been able to dig up as well.

I�m willing to accept the answer �it interrupts the combustion cycle� but I need to know how. So I go digging a little bit about the chemical family and what they do and doing the best I can while knowing very little about chemistry I�ve come to discover that Bromotrifluoromethane is a haloalkane. That family tends to react with Nucleophiles, a notable member being Oxygen.

The MSDS specifically calls out the use of a SCBA in oxygen deficient environments (why are they on fire if no oxygen?)

You can know a lot about chemistry and still call reaction inhibiting extinguishers magic.

Haloalkanes are incredibly non reactive in a broad range of conditions so it being a nucleophile and reacting with oxygen is a bit of a red herring unless you're worried about the ozone layer. Which, well, famous problem with them being non reactive until they reach the upper reaches of atmosphere and UV catalyzed reaction with ozone happens to an amount of depletion of the ozone.

Second problem is when you make them too nonreactive with ozone and there's a greenhouse effect so it's hard to win with these chemicals.

Anyway how 1301 works is sort of a reverse catalysis. All those big honking halogens should be out there getting on fire too. But remember it's pretty non reactive. It's possibly reacting a few times in endothermic ways but it's largely there being a radical problem for the whole reaction chemistry requiring energies to solve that aren't present in the fire. If we were to assign anthropocentric attitudes here the fire just gives up at the exhaustion of trying to burn the combo of the fuel, oxidizer, and 1301.

You don't need oxygen replacing amounts of it to fight a fire and the handheld canisters for planes and tanks are sized to not choke you out of the thing. Room dump units are a different story because they have timers and alarms such to get people out before the dump. So even though they're used to dump in not oxygen replacing amounts , there was a fire burning in a close room for a little while and if you need to enter or do anything before they've been cleared for oxygen content you should enter with a SCBA.

Fun huffing fact. Many haloalkanes are anesthetic. They are non reactive so not really stripped by your liver while being able to enter your blood stream and pass into brain and spinal fluid at rates that make you loopy well before oxygen deprivation. If you feel loopy after a discharge this is playing more of a part than oxygen deprivation.

I like your exhaustion analogy.

In really basic fire science terms the chemical agent is removing heat energy from the fire triangle to slow/inhibit combustion. Really no different than using water, but you trade duration for lack of a giant mess.

An alternative clean agent approach is removing oxygen, of which the most basic approach is straight CO2 which is super effective minus the it�ll kill you too component. On the other end of the spectrum you get something like Inergen which dumps a bunch of noble gases into the room at a very specific ratio to room size to drop the oxy% enough to stop combustion without asphyxiating the room occupants. Super expensive though.

Halon's aren't contained by basic fire science terms. The fire triangle is an oversimplification. Not remotely similar to water, which CO2 is sometimes compared to cause most CO2 systems vent it cold as hell for thermodynamic reasons so you sometimes kill a flame before total exhaustion of oxidizer.

People sometimes extend the fire triangle to fire square when talking about halons and add the extra vertex of 'reactivity' which is usually a foregone conclusion once something is on fire, because fuel caught on fire and its obviously reactive with an oxidizer. Mixing halon in messes with reactivity for mostly indescribable reaction intermediate radical bullshit reasons. I'd rather call it magic than apply a fire triangle or suddenly spring a fire square on someone, which is just all of reaction chemistry to worry about now. A wizard did it.

# ? Feb 5, 2023 17:52

Sagebrush: Feb 26, 2012

You don't need to make a fire square or anything. Halon is just planting its foot right in the middle of the fire triangle and preventing the three components from getting to know each other.

quote:

As the day wore on, winds grew stronger and stronger. Frequent values of 220 mph were recorded between 12:00 and 1:00 pm, with occasional gusts of 229 mph. Then, at 1:21 pm on April 12, 1934, the extreme value of 231 mph out of the southeast was recorded. This would prove to be the highest natural surface wind velocity ever officially recorded by means of an anemometer, anywhere in the world.

fire creates a oxygen deficient atmosphere some times by using up all the oxygen or too much of it to allow for people to breathe. but also the composition of whats burning can mean that the reaction provides its own oxygen

The weather up there is insane, especially for a relatively small mountain, I learned all about it, and the many people who have died on Mt Washington, by reading a book in a hikers shelter nearby after almost getting hypothermia after getting stuck in a rainstorm-turned-blizzard in June. Which it turns out is why a series of cabin/shelters was erected in that part of the White Mountains.

You can drive up it in the summer. But during winter it's a fairly long hike and people tend to not take it seriously which means their rescue teams can get fairly busy. My climbing partner and I got roped into helping with a search one time after we had just finished fooling around on one of the more alpine routes up.

There is a TV show about GF&P officers in that area and it seems like every 3rd episode involves a search for a missing hiker on Mt Washington.

Yeah people don't realize that east coast climbers will go there to practice for pretty serious mountains since the weather is horrific and can turn bad really really quick. And once visibility goes down there are parts of the hike that get pretty sketchy if you haven't done it before and it's really easy to get lost. But because for the main route up you don't need any climbing gear a lot of people view it as a hike and that's dangerous

This is the terrifying moment a truck driver pulling out of a petrol station in Russia crushed another customer.

CCTV footage captured in Abakan on February 23 shows the truck starting to pull away after refuelling.

A customer at the pump spots the long vehicle is coming very close to his car and stands between the two vehicles attempting to alert the trucker to the danger.

As the larger vehicle's trailer swings around, it traps the man against the side of his own car and crushes him for several seconds.

According to reports, a 45-year-old resident of Bashkortostan seriously damaged one hip but avoided life-threatening injuries.
