The Smokin' Science of Fire Extinguishers

Different fuels create different types of fires, and each one needs to be extinguished using a specific strategy. Do you know which class of extinguisher is needed for different fires?

Not really a pun. At most a throw back joke

[@killagilla88]

That was a beautiful catch.

I don't think that's what a pun is...

[@prescribedfire1953]

Greetings SciShow. For the past 50 years or so fire has been my business. I was in the fire extinguisher/fixed fire system field primarily as an instructor. Later I was employed as a full time firefighter and currently as a hazard tree faller for Cal Fire. This video is one of the best I have seen. It had a couple of minor mistakes but overall it was good for the average person. I do believe you should have said the ABC multi purpose dry chemical is the extinguisher everyone should have in the home. The other types are only for industrial/commercial use. Keep up the good work!

[@TrialzGTAS]

But why make posts like the one i'm responding to at all, if they're unhelpful? Just copy and paste (tweak a few sentences to get by the spam thing) and you'll be educating people instead of just complaining.

[@torrqueable]

No there aren't, as a FFT I'm confident that I have a good grasp on the subject

[@gordonlawrence3537]

torrqueable for a start the chemistry is wrong. EG all you need is ANY reducing agent for a fire and oxygen is just one of them. Flourine would do in many cases and magnesium will even burn in carbon dioxide. For fat/oil fires you ALLWAYS smother them and in a kitchen that is best done with a fire blanket or a heavy damp towel and Red Adaire demonstrated how that can be done with water in the case of a very large fire - and you get trained how to do that if you ever work on an oil rig in the UK. There is no fire tetrahedron it's a fire triangle all you need is heat fuel and a reducing agent and you have fire. So you are an FFT are you? LMAO where did you get your certificate? A cornflakes packet?

Why does steam get rid of wrinkles in clothes?

[@dawsongranger4940]

There's more than just steam that goes into straightening clothes.

[@Skylerfi]

It's not just steam, it's the heat. The heat breaks the hydrogen bonds between the molecules in the clothing you wear. Once it's cooled in the flat shape that the iron has created, the hydrogen bonds reform and hold the shape and thus removing the wrinkles.

I worked in warehouse for a few years and learned this as part of the safety courses issued by the company. It makers perfect sense in a warehouse environment as we may experience each one of these issues and because of the type of environment it is makes it extremely practical to keep and store an alphabetical arrangement of the different types of extinguishers. I ain't got time for that at my house.

[@tblo]

Recently I found myself curious about something, Ive looked it up years ago but couldn't remember the details and thought for sure scishow would have a segment on it, but if they do I haven't found it, but as I really like their style this is my pitch for asking for it! Fevers! Why does your body respond to infection with them, what does it hope to accomplish in raising your temperature as such, and what mechanisms does it use to accomplish the effect, plus any other related science-y details that are relevant!

In Scouts, a couple guys made a candle using a can and some wax. They couldn't put it out, so I suggested using some dishwater. They poured some water on it, and immediately a 15 foot high column of flame erupted from the candle. It singed the eyebrows of the guy holding the candle on the stick, reduced the stick several inches, and could be seen on the other side of a small hill. Burning wax and water don't mix.

[@harrietharlow9929]

LOVE the title of this episode! My partner and I became homeless in 2017 after a house fire burned down our rented flat. Not our fault--the fire was caused by bad wiring ( my landlord had the building built on the super-cheap). I 've got this on my Scishow playlist!

[@ewllen808]

That "save your bacon" pun was spectacular, I am in awe.

[@hikaru-live]

If you have a kitchen (cooling oil or grease) fire and no extinguisher, any one of the following would also help: the matching lid of the pan (to choke off the oxygen supply of the fire) and wet leafy veggies (the water content reduces heat; while the plant material acts like a lid, trapping the burning oil droplets from flying out)

[@ariccastro]

The dry powder coats everything when you use an extinguisher. Some of the extinguishers use a colorful powder that shows up on clothing. Shutting down the power is usually the best for class C fires, then you're left fighting the material that is burning from the electrical fire. That's why most departments try to shut off the utilities to a building before engaging in fire attacks

[@cajagato]

Could you guys do a SciShow on what fire actually is? I've never been able to get a description that makes sense to me from anyone. Specifically, is fire a form of matter? Is it a substance that exists as either a gas, solid, or liquid? I'm told no. However, at times it behaves like a gas. Large fires can even flow down staircases like liquid. What the hell?

[@vifurawa2715]

no

[@JesReally]

I had no idea that there were different types of extinguishers - this is the shit they should teach you in school!!

[@1997jankuschef]

Really interesting. Since most households have ABC fire extinguishers, it seems like they must work at least ok on K type fires, because it's all that's available.

[@youmaycallmeken]

For a grease fire in a pot or pan, if the cover is in reach, wouldn't it be best to shut off the stove and place the cover on the pot (with an oven mitt if necessary). If the cover is not close by, then a completely wet (but not dripping) towel can be used to cover the pot.

[@Laezar1]

That... was actually rather helpful owo' I just hope fire extinguisher are classified in the same way where I live, but this might one day save my life!

[@Fredengle]

where do you live The UK system is different the system they mention above is the U.S system!

[@Laezar1]

@@Fredengle France lol, also this did not in fact save my life and I totally forgot about it in the meantime =p

[@FoddMasterZim]

Good job guys this is the only funny bacon joke I've ever heard. Also thanx for you know saving my life.

[@stellarfirefly]

It should be noted that a Class B (U.S.) extinguisher may also be used for oil/grease fires. The Class K extinguishers were made for larger oil/grease fires such as in industrial kitchens. But for smaller kitchen fires, both Class B and Class K extinguishers will work. Just be careful to not "splash" the oil around with the usually higher pressure exhaust of the typical Class ABC extinguisher.

[@janweber2889]

Apparently +SciShow hasn't seen many pan fires, because the best way to put them out is just to drop a lid on the top of the pan. You would only need a fire extinguisher if somehow the fire spread to areas outside of your worktop/cooking surface.

[@MrHeems]

I had an AK fire in my oven once. I had forgotten that there was a plastic container in the oven and turned it on to preheat. A few minutes later I noticed smoke coming from the kitchen. I opened the oven and the added oxygen make the fire flash and almost took my facial hair off. I quickly closed the oven, turned it off, reopened it to splash in a pot of water and slammed the oven closed. It did put it out, and I spent the next week cleaning soot.

[@PrestigePotato]

[@skbartistry2473]

At this point my bacon is long gone and my neighbours are frantically calling the fire department, cause I dont have a fire extinguisher...

[@poeslaw1648]

Also class F fires, F is for FOOF. There is no way to put it out other that waiting for it to stop burning, it also burns everything, glass, stone, asbestos, and explodes in water or moist air.

[@SteveIsHavingMC]

thats fluorine fire right?

[@poeslaw1648]

SteveOwnsMC Yep Fluorine and Oxygen. Toxic, will ignite at any temperature above -230, creates many toxic gases and acids as it burns so even after it's done it's still dangerous to be in area.

[@SteveIsHavingMC]

Heard that a tanker with that stuff spilled and it burnt 1m of concrete gravel and dirt....

[@amperzand9162]

I believe you are thinking of CFl3. Chlorine triflouride, not diflourine dioxide.

[@typograf62]

First choice when the bacon is on fire and like fires may be to put a lid over the frying pan or the pot. Always know where a lid of the proper size is. A fire blanket is also good if you know how to use it. In a few cases it may be possible to put out a fire in oil or gasoline with water, but it is more like a party trick than practical. The fire has to be in an open barrel or pot and then you cover the space above the burning fluid with water mist. A bucket pump can do the trick. Maybe.

[@mantonyz]

We had a yearly fire extinguisher training at work last Wednesday.

[@robroysyd]

The "dry powder" extinguishers can be used on kitchen fires however they should be sprayed upwards to let the powder settle on the burning oil. Another types of extinguisher that can be used on burning oil in a kitchen uses damp oatmeal. Even with these it's important to not spray them at the oil or it'll likely spread. A fire blanket is a good thing to have on hand in the kitchen but even that does need to be used with care. Everyone in a household should know what to do in a fire and how to use basic fire fighting gear. Alkali metal fires need an extinguisher that contains glass beads. The glass melts to exclude oxygen and water.

[@cloudsplitter24]

I'd be curious to get the SciShow take on the fire extinguisher called Cold Fire. Demos are pretty interesting.

[@DeAthWaGer]

to save your bacon, use a lid, not an extinguisher!

[@meetaverma8372]

Pro tip sir

[@Gaehhn]

I Germany the classes are: A: Solid ordinary fuels B: Liquid fuels C: Gasses D: Metal E: electrical appliances (there is no specific E-Type fire extinguisher, the are usually labelled CO2-Extinguishers) F: fat/oil/grease Also the best way to put out a fire in a pot in your kitchen is by putting a lid on top, if you don't have anything fitting around you can also use a thick blanket if you use it quickly. Some extinguishers meant for burning oil are not really the best way to put out burning oil as they might still spray around the oil creating a huge fireball. At my local fire department we tested some cheap ones some time ago and I'd recommend none of them.

Im a fireman and this is how I remember them and what they are used on: A = Ash (wood, combustibles) B = Boil (liquid) C = Conduct (electricity) D = Dent (metals) K = Kitchen

[@ThallanarRabidtooth]

How I learned how to combat grease fires (Or 'K' fires) without a 'K' extinguisher: Get a lid and cover it. It removes the oxygen supply and basically smothers it. Whatever you were cooking might be burnt to a black crisp or perhaps you seared your steak just the way you like it really quickly... Either way, it works.

[@reginaldknowles3890]

I love this channel.

[@TechItOut]

In the UK we now have water extinguishers for electrical fires. CO2 and Dust are being phased out. Water Mist Extinguisher (‘Dry’ Water Mist) Water Mist Extinguisher Signal Red on a White Background Best For The first broad spectrum extinguisher to tackle A, B, C rated risks as well as fats and deep fat fryers (Class F). Models with dielectric test to 35k Volt can be safely used on electrical fires (up to 1000 Volt) if a safety distance of 1m is adhered to, as their mist (de-ionised water) does not conduct electricity and the extinguisher does not normally form puddles, which could conduct electricity. The E-Series extinguishers also contain only de-ionised water which cannot carry any electric current. How to Use Point the jet at the base of the flames and keep it moving across the area of the fire. Ensure that all areas of the fire are out.The fire draws the microscopic water particles into the fire How it Works Water is turned into microscopic particles in the supersonic nozzle. The water mist is drawn to the fire where it cools and suffocates the fire. The mist also forms a safety barrier between user and fire, which keeps some of the heat back.

[@maverickbna]

Could you cover clean agents? They are commonly used in data and telecom centers around expensive electronics, and when they are used, they don't leave a residue that can damage electronics. I'm talking things like Halotron, Novec 1230, Inergen and Argon. Thanks for covering this! It was very informative.

[@ronniessebaggala362]

This video was lit.....

[@Alalias]

The first time I used a fire extinguisher I discovered that a small 3 pound ABC (dry chemical) extinguisher has only 3 or 4 seconds worth of squirt. It's sufficient to put out a fire in a small office trashcan...probably. But it'll just piss off anything bigger.

[@bradstone2603]

in Australia we have a lithium classed fire extinguisher, fine copper powder propelled by 50 bar or argon gas.

[@DarthRevan42]

Thank you! I never knew!!!

[@killagilla88]

I think this is a very well done video and something that people should really be more aware of however I was disappointed that you didn't also mention that using an ABC fire extinguisher on people, like we see all the time in movies, is a really bad idea and will just give them chemical burns.

[@nickmceachern3373]

I dig this, cheers!

[@DustinRodriguez1_0]

If your bacon, or anything in a skillet or pot on your stovetop for that matter, bursts into flame... don't grab a fire extinguisher at all. Grab a cooking mitt or wrap your hand in a kitchen towel or similar, grab the handle of the skillet or pot, and remove it from the heat (while turning the stove off). Either cover it with a cover made for the skillet/pot, or take it outside. You only really have a serious problem if the fire has spread to other flammable surfaces in your kitchen. Fires burn out when they run out of fuel. Just make sure it can't spread, and probably take it outside so the soot and smoke doesn't cause problems inside or, preferrably, just cover it and it will starve itself of oxygen nearly instantly.

[@maccrazy7335]

Since almost no one had a fire extinguisher when I grew up, we were taught to, if at all possible, put a glass or metal lid over the burning pan...

[@MrRishik123]

Ima keep this info handy when recording my mix tape

[@maverickbna]

Could you cover clean agents, such as what used to consist of Halon-type extinguishers? I'd like to hear a more detailed overview of these agents, such as Halotron, Inergen and Novec 1230.

[@lauraameliarr]

That stove-burning picture is the one people use for the Sims meme

[@Kram1032]

I don't quite see the difference between B and K fires. Both are about flammable liquids or gases which either don't care about water or simply are spread around more by it, right? Or am I missing something?

[@re46tygrews7x]

Class K are liquids that resist water like oil. Class B are liquids that don't resist water like gasoline.

[@schwarzerritter5724]

I guess the difference is that fat and oil only burn if you boil them or use a wick.

[@TechItOut]

Class K are explosive when water is in contact with them as the water instantly vapourises into steam

[@NahmiiVuhuni]

This was mentioned in the video. Water doesn't work on anything bar A, and K fires pretty much ignore dry chem's foam blanket. Firefighting is more science than manpower, that's why we spend so much time in a classroom compared to on the field.

[@windyswimming520]

the fuel in the kitchen fire is usually contained in heavily insulated containers and the containers are relatively deep so the fuel maintains the high heat and combustion level so that a regular ABC extinguisher isn't effective. the were Chem k extinguishers work with the hood systems to create a thick layer that separates the fuel from the oxygen.

[@dagwood1327]

Where does Halon gas exterminators fit into the scales of things?

[@oogieboogie232]

Its different, though there are handeld extinguishers. In terms of the tetrahedron described, Halon and similar agents circumvent the chemical reaction (oxidation) with its own reaction, using up the hydrogen the oxygen would have bound with.

[@spud4242]

halon is used in data centres for electrical fires... trouble is it is very expensive. went through incuction for a 2 floor data centre and the cost of the gas was $80,000 AUD... then he goes on to say "dont worry about the cost, if there is a fire and you think you need to pull the gas ,just do it".. lol supposedly it takes away enough oxygen to put out the fire but enough so if you are caught in it you wont die... not going to try that one!!

[@hart-of-gold]

Only really for large electronic and electrical systems for a few reasons. First they're good because they don't damage surrounding systems and disapate completely so repair and restart time is shortened. Second, they will put out basically anything and are inert. But they are the most damaging chemicals in the ozone layer and they are covered by the Montreal Protocol. So you need a good reason to use one.

[@travisscavoni369]

Halo can also be used in professional kitchens.

[@Skylerfi]

From my current knowledge, early Halon extinguishers are completely banned from civilian use due to the Montreal protocol as they contain tetrachloromethane and methyl bromide which both deplete the ozone layer. Current usage in the UK is by the ministry of defence, police and I think the underground international rail systems. Current Halon extinguishers use bromotrifluoromethane. Problem is once in use against the fire, in this case, solids or liquids, hydrogen chloride gas is produced.

[@iota-09]

i just realized he said "most common fire extinguishers in households" you guys in the usa have fire extinguishers in your houses? what a time to be in a wealthy country.

[@sixlugchris3747]

also if theres an electrical fire in an area with sensitive electronics, like a server room, they always use CO2 fire extinguishers because dry chemical can damage the electronics even more

*Save yourself with a class K fire extinguisher before saving your bacon.

[@asyyfjd]

I am really surprised how approach for extinguishing fires in USA differs from that in Poland where I live. For example for K fire type (marked as F in Poland) we use potassium acetate foam, and for A type fire we use NaHCO3 or KHCO3 powder.

[@Fredengle]

that would be strange as what you mention are baking soda and purple k both agents are only rated for liquids and l electrical fires!! they are not rated for class a fires as they do not work well on paper fires! foam would be dangerous on a Class F fire because it has a high water content!

[@amperzand9162]

Running shoes.

[@thomask2006]

You run like hell

[@nlotsobabies996]

Now I know what to do outside my own country

[@AfonsodelCB]

am I suppose to have a fire extinguisher at home?

[@skyr8449]

yes

[@xaderalert]

Preferably multiple. (I'm assuming your home has a kitchen and also many things that are not a kitchen, yes?)

[@LadyAnuB]

Yes, an ABC extinguisher which you should have inspected yearly. If you live in an apartment complex, an extinguisher should be within an easy distance of your apartment.

[@AfonsodelCB]

I live in a house, in Portugal. I don't remember seeing a fire extinguisher at anyone's home, but maybe I missed it. It does sound like a good idea

[@Borednesss]

You also are required to have one on a boat if it has an enclosed cabin

[@Random_Canadian00001]

good to see you went past the triangle and ABC

[@Rayne1936]

A b c d and k... Science WTF

[@vectoredthrust5214]

Rayne1936 "K" was probably developed much later when it was realised that you needed a special extinguisher for kitchen fires due to the unique setup of hot oils/grease and heat sources below. So given that it's designed specially for kitchens, "K" makes sense

[@FrenchLightningJohn]

a type B extinguisher work fine with those fire, the type K was surely invented for restaurant that didn't like to close the restaurant for a few day just to clean it from the chemical

[@shashwatsharma2406]

Great

[@navilhernandez6633]

This video is lit ;)

[@youmaycallmeken]

Would keeping baking soda in an easy to open wide container be a good homemade extinguisher to keep in the kitchen? Would baking soda work well on all the types of fire mentioned? What about salt instead of baking soda. What about sand?

[@Tigermanic21]

I was never taught about a class K fire in school, and always assumed it was comparable to a class B

[@KeaLynn]

what kind of extinguisher is usually in houses? because my sister caused a grease fire and our fire extinguisher put it out but you said most of them are water fire extinguishers
