J Trane To know that this flame will spread this way across the door and up across the ceiling, not because of the physics of flammable liquids, but because it wants to.
Notice how after he closes the door after the backdraft at 7:45 the smoke on the roof changes from thin white smoke to thick fat dirty brownish yellow smoke. Also, the smoke comes through every gap in the top window. This is something to alert you when you approach a burning building: There is heat and fuel, just not enough oxigen. Be careful about venting.
When I was 20 years old, living in Sudbury, my neighbours house caught on fire. I watched the firefighters doing their thing. Two fighters were on the roof, and when they cut a hole in it, it was light an explosion. Fire spewed out 20 feet into the air like a blow torch. I felt the heat from across the street. What was so crazy though, was the fire fighters, who were completely engulfed in it, continued on working like it was nothing. It blew my mind, how 2 people completely on fire, could go about their business like it was nothing. It really made me appreciate how dangerous the job is, and the grit fire fighters must have.
actually its not even uncommon their are quite a lot of arsonists that are or where firefighters ... its like being addicted to drugs you cant get enough of them fires i think...
Ok, this is a really cool simulator. I'm going to have to pinch this idea & build some props for our own brigade training based on local retaliate. Great job.
Any questions after this demonstration on the vicious behavior of fire you just witnessed to make you a more aware firefighter?... “How long it take ya to build that” lol
Man everyone in this comment section could build that in less than 5 hours AND knows everything about being a firefighter. Why don’t they just start hiring from comment sections??
There is a waiting list to be a firefighter where i live. I don’t wanna hear anyone complaining about the job. It’s dangerous but your not volunteering and there is a lot of safety precautions
they pretty much do actually. most firefighters start as children volunteering to go get themselves killed. the ones who survive end up being fire fighters because it pays far better than most jobs, has no real requirements, and you get the "hero" factor for doing something you get paid for. protip: heroes arent doing things for a paycheck.
Anyone else noticed that by venting the roof he promoted fire progression throughout the second floor of the house when prior to ventilation it was just filled with fire gasses
People that watch too many of these videos end up wetting the bed. They dream "Uh oh, the bed is on fire, quick pull out the hose! Turn on the hose! Okay, hose everything down to put out the fire".
7:20 is flashover, the smoke reached fire point. BACK DRAFT is a hell of alot more explosive, there was no churning of smoke(bellowing) Now before people start saying:" what the hell would you know? My reply: 12 year I.F.S.A.C/N.F.P.A Level 2 Firefighter. I also agree, they need to shut up while he's teaching.
@@HeavyWindBreakGlass i meant so the fire doesn't rage. Say you already got out of it and could still close off everything. Would that be the best thing to do until the f.d. showed up?
@@thejohn6614 Bro, both of those comments were sarcasm lol. But to get serious, judging by basic grilling and science, you'd close everything off to smother the flame as much as possible. Of course that depends on the size of the flame already.
What he fails to explain is that a backdraft is not the fire's fuel exploding into flame, but carbon monoxide (CO/Woodgas) from incomplete combustion. When oxygen is limited or cutoff, a fire's fuel will continue to oxidize/burn, creating higher concentrations of highly flammable CO instead of carbon dioxide (CO2) gas. When oxygen is restored, the CO can/will explosively oxidize. Additional fact, what we call flames are actually a second combustion event. Flames are the result of rapid oxidation of exhausted gases (mostly CO) from the first combustion. A wood fire is the oxidization of the wood fuel, which then throws off copious amounts of CO that then oxidizes into flames.
I saw a video where firefighters used a 15 or so foot long shipping crate to demonstrate backdraft. It was massive and incredibly loud and powerful. Is it possible to get a powerful backdraft from that smaller scale house? If you have a smaller ventilation hole, will the backdraft be more powerful or do you just need a greater volume of smoke?
Awesome video. Would like to see this done with A water spray bottle with a nozzle to show different affects droplet sizes have with gas cooling methods
What he keeps doing is deprivating the fire of oxygen when it's got tons of fuel. Basically making it burn too RICH. Then he feeds it oxygen creating a back draft scenario and it fires back up. He was lucky that one time he didn't burn his face.
foramagasobeselettucepurplergasmup Facial hair actually protects you in a fire, I saw the results of a LPG explosion and the only parts of the guy's face and torso that didn't get third degree burns requiring skin grafts were those protected by his beard and moustache. The skin in those areas looked virgin, no injury at all.
Say you're giving a fire demonstration to a bunch of people, and your fire goes out unexpectedly! It's still hot in there, but there is no air! What are you gonna do?? LETMESHOWYASOMETHING!
What scares me is that it seems unpredictable. I mean, we know the conditions that make a backdraft, but when those conditions get met are hidden within the structure until you open a section/window etc. Like around 9:20. How do you know, when you get to a scene, if the thing is going to try kill you or not? Edit: and what if you are on a crane near the roof at 9:50? Can making a hole put you in danger? Guess that's why I'm not a fire-fighter...
Some signs that firefighters can use to identify a backdraft: First of all, keep in mind that to occur a backdraft the smoke has to be very hot and concentrated enough with combustible, only lacking the O2 to ignite. 1 - Khaki/beige, dense and turbulent smoke getting out violently from upper openings 2 - Air being "sucked in" the building, you can see it and also hear a whistle sound 3 - The presence of flameover (smoke getting out the building and instantly igniting), which means: The smoke that gets out of the building is hot and has combustible enough to burn and it will burn as soon as O2 enters the game 4 - High temperature doors, door handles and walls indicates that the inside of the building is very hot 5 - You will hear stuffy noises, due to the high density smoke 6 - Windows will look oily, due to soot and water mixture (products from the combustion)
fire moves much much faster than the average person imagines if you have a fire in your house get the people out dont wait if you do people will die and if you are building a home now or in the future have sprinklers installed in homes with them no one dies
When you hear about firefighters dying in a fire it’s most likely not because of smoke inhalation, it’s probably because of them getting caught in a backdraft that got them all disoriented.
I'm glad none of the fires I lit went cuckoo. We had a sheriff show up at our bonfire to let us know he could see it from 15 miles away. He thought it was something serious. Nope just 6 guys out with a truck picking up dead brush and dead trees, limbs and stuff then burning it. We did it over a sand pit in the forest .
I watched something similar to this the other day and someone commented asking where to get the plans to make it. Man, if you need to aquire plans for something this fucking simple then you don't need to be on the fire department. Period.
This is why you close doors and windows as you evacuate. Also Firefighters can take opportunities to strategically vent fire away from victims inside. 🏠 🔥 🚒 🌊
Barbie and Ken were devastated when they found out...

Fern Cha well, no. The hand can cut off oxygen but as soon as the fire is re introduced to oxygen it blows up like a bitch

Its kind of weird watching a fireman start a fire.
actually its not even uncommon their are quite a lot of arsonists that are or where firefighters ... its like being addicted to drugs you cant get enough of them fires i think...
Alot of wildfires become offset due to firefighters lighting fires to defend against the oncoming wildfire
I wish the people behind the camera would shut dafuq up
It happens that many are arsonists
I wonder if someone called and thought that their was a fire 😂

sooo..if my house is on fire...close every window and door and wait till it's over I guess
i don't think a conventional glass window would tolerate the heat

Get out first
Uhhhh. No. Lol just run tf out and call 911. Compartmentalization will help contain the fire but trying to close everything will kill you.
