@8550ranger Not to come off as a know it all but The only difference between a flashover and a backdraft is the cause. The results can easily be the same. I have seen flashovers blow out windows. the concussion happens due to the speed of the oxidation if the flashover is fast enough then BOOM can has and will happen. be it not as common with a flashover but none the less it does still go boom on a fairly regular basis

It doesn't really matter how old the fire is. Many countries are happy to have any PPE at all. Several countries take our(North American) old expired PPE as donations.
This is a great example of what a backdraft. CO that is too heavily concentrated in the air to flash, is suddenly mixed with oxygen. As the mix of CO in the air is thinned by the oxygen, it reaches its upper combustable limit (74% concentration in the air) and explodes. Those poor guys on the platform didn't know what hit them. This backdraft was probably partially caused by the stream of water they were using. It helped introduce oxygen into the environment. Just glad they survived.
Smoke gas explosion. The smoke and gasses within the structure are hot enough to ignite but dont have enough oxygen to do so untill it escapes the structure and mixes with the oxygen rich air outside.
well im taking fire 1 as of now, and to my understanding this is a backdraft, the signs, are the smoke goin in,out,in, and out cause the fire is looking for oxygen, and those bursts of orange flames, and i still have to get a better understanding of smoke explosion but i know backdrafts have that characteristics of an explosion
@grimbomufc09 the video states that there BA was taken off them after the explosion so that would have prbly taken most of the damage there lucky the BA didn't melt to there face but it seems no no burns to the face
A plastics factory and theyre in a cloud of smoke with no SCBA... thats genius. They survived the blast just to go on and enjoy cancer later in theyre life. Byproducts of burning plastics is one of the nastiest things you can expose your lungs too.
a backdraught is where the fire has been starved of oxygen, the fire keeps burning and items in the room pyrolise (flammable gases given off by everything at certain temps) and fill the room with flammable gases. Once a door is open oxygen can come back into room re igniting the fire and all the gases creating a rapid fire increase
Flashover is when all the material reaches it flashpoint (the point at which the material gives off gas) and ignites, every thing in the room that can burn burns.
Backdraft is a point in the growth off a fire typically in the decay stage. The fire is starving of O2 the smoke seems to breath out of the building, also smoke will change colors from gray to brown.
Rollover is when unburned pockets of gas ignite on the ceiling. They move across the ceiling.
@MrStureef Hey man I see the instructor and the firefighter arguing above, but u seem to have given the most clear and agreeable definitions of flashover and backdraft. I have to agree with u. =)
@slim404 FLASH OVER = Everything in the room ignite..being solid or gas, you have the fuel you have the oxigen. BACKDRAFT = You have a room, full of inflamable gases but u dont have the oxigen for them to ignite...give them the oxigen and the gases will "KABOM"... inflame and explode.
@MrStureef That's inaccurate. A liquid can give off vapour below its flash point, which is the point at which that vapour mixture can ignite to cause a momentary flash. The point at which it continues to burn is the ignition point or fire point, not the flash point. Flash over is when the all the materials in the compartment reach their auto-ignition temperature, not their flash point. They then ignite simultaneously causing flashover.
Rollover is not just gas but the smoke igniting too.
To all firemen "that have to know" - just look for other videos on youtube with a description containing the word "backdraft" and soon you'll see how wrong you are. This is a backdraft.
if you seriously think this is flashover you are wrong. this is a very obvious case of backdraft. the fire looked like it was breathing, the smoke started forcing its way out, and you can obviously tell by the smoke that it was fuel rich and starved of oxygen, the water kept the fire cool and from further ignitng. they shut the hose off and the fire found more oxygen and caused a backdraft
Why are people saying this is a flashover? You can see the smoke getting very turbulent right when the backdraft is about to happen. That's a good indication that there's an upcoming backdraft. A flashover would be the smoke in an enclosed room and then they all reach their ignition temperature.
just to settle this discussion, i am currently doing my breathing apparatus section of my fire fighter training and we have just covered backdrafts and flashovers etc today. a backdraft occurs in a compartment when the mixture of fuel to air is very rich, thius causes the fire to begin to die as it is running out of oxygen. when a door/window is opened and air is reintroduced to the mixture the fire begins to grow once again until it reaches its optimum ignition ratio and then it ignites rapidly
@addicted2firefightin I'm pretty sure it was a backdraft. As you can tell the oxygen was fed to the fire which caused the buildup and possibly someone opened a door a window which caused the backdraft.
"A smoke explosion requires a relatively cool mixture of fuel (smoke) and air within its flammable range to come into contact with a source of ignition. On the other hand a backdraft requires introduction of air to an hot, extremely ventilation controlled fire where the concentration of gas phase fuel (smoke) is high and oxygen concentration is low. Both result in an explosion, but the initiating event and indicators ... are considerably different."
to be honest i cant say this was either, seemed to powerful for a flashover the billowing smoke would indicate a backdraft as the fire trying to breath, but that's a massive fireball and would indicate something inside the factory exploding
I have no way of knowing what caused this, but I do know that plastics factories can have a surprisingly high risk of explosion, depending on what they are making. The raw plastic they put in the molds can range from grains the size of a marble to the consistency of flour. It's the latter that can be a problem if the particles are allowed to become suspended in the air. It's similar to what can cause grain silos to explode. Certain types of pigment used to color the plastic are even worse.
Ive been a fire fighter for three years in the brentwood fire department this is a back draft flash overs do not explode like this that did not flash at this point im sure it flashed either as soon as they got there or a minute or to before im in the busiest fire department on long island believe me i know
hahaha, i guess people dont get enough arguing and shit slinging at a scene, they gotta do it here to.
anyways, great video, CJfin, glad everyone survived. The instructor showed us a clip of this in fire fighter 1and you could hear an audible "THUD!" because the whole class's jaw hit the floor,haha!
@firedept35 Well mr science. To wake you up. They might have kicked in a window that causes ventilation. This may have caused the large outflow of unburned pyrolyse products. This ain't a flashover.. The closest thing that would be is a smokegasexplosion or a high pressure backdraft (caused by to much + pressure)
Another thing. Even with area's where oxygen flows in, it is possible to create a backdraft, so what you just said about it cant be a backdraft is total bullshit
@backdraftmagnet you are totally right. and firedept35 he would never get a promotion at my fire department @ any of the 13 stations we have in my district. what a dumbass. but lets get one thing straight tubesteakdynamo im from a southern fire department, and we do better than any of you yankee bastards that just wanna go in and spray water.
@marequizwcav im a dumbass, real nice and im guessing they give you a promotion down there for being a asshole to other firefighters. I could care less but your insulting another firefighter real nice
OK 1, its not a flashover Cenobyte78, sorry. Maybe somewhere in the building there was, but not there. 2. There is a difference between a backdraft, and a smoke explosion, usually you can't tell, but in this case, notice the smoke. It was what you would call 'breathing'. When smoke exits, it creates a vacuum that pulls air in but with a backdraft, it also pulls smoke back in sue to the lack of air. This is why it may be a backdraft. Now, to be a smoke explosion, the smoke must rapidly catch fire
this could be a back draft, there could have been a separate fire in room down stairs which could of just gained oxgen if u watch the fire ball comes out through a window down stairs.
agreed. why were they not wearin scbas? and no this isnt a backdraft. there were open spaces where oxygen would have already been present in igniting the smoldering flames. which it didnt. i agree this has characterisitcs of a smoke explosion
this is no backdraft. to have a back draft you need a closed off space with little to no flame then a suddent rush of oygen to ignite the fumes. this is either a smoke explosion or flashover. the smoke didnt really seem black enough to be a smoke explosion but its possible
it's neither backdraft or flashover it's a smoke explotion the smoke isn't black so its not full of carbon, it still has fuel, the water was keeping it just cool enough remove that and the in the fuel in the smoke ignites
If all you see is a lot of smoke and dying or no flames at all, then get the hell away from the building!!! Dont wait to see whats going to happen. And wear some SCBA!!!
do you even know what you are talking about, you better shut up then, that is a flashover, backdraft is when a dying fire gets fresh oxygen from a opening door or a broken window, the windows and front door were already open so its not a backdraft, its a flashover, flashover is when everything in one room or floor reaches the combustion point and everything burst at one time, they stopped water for acouple of seconds let it get to hot in there, thats what happened smoke explotion is possible to
@firedept35 < that was neither flashover nor Backdraft. That was a chemical explosion from the barrels of solvent on the bottom floor. Listen to your self...they stopped putting water on the upper floors and you say that caused the BOTTOM floor to flash???? Dumb shits. You must be from a southern hillbilly dept.
@tubesteakdynamo dont call me a dumb shit, im just saying my opion man, im guessing your a firefighter idk why your talking to another one like that, and what the point if i was from the south you think your some big shit because your from a city, and trust me that was no chemical explosion i can tell you that
@firedept35 <Opinions get people killed. Training and common sense, that's how you stay safe. As an instructor I call shit like I see it and I'm NOT sorry if that offends.
@tubesteakdynamo ok asshole you say what you want to, and assholes like you kill people in fires if you act like this, and nice page im the jackhole FUCK YOU. seems everyone hates you. thinking your big and tough on the internet you aint worth my time
@firedept35 , Well, it's definitely not a backdraft; firedept35 gave the correct definition of one. tubesteakdynamo, I'd be interested to know where you got your information that solvents on the bottom floor ignited. It looked like fire came from both the first and second floors to me, and that the smoke hid the fireball from the second floor from the view of the camera. This is all just speculation though. I'd also be interested to know why you would insult a fellow firefighter. As an instruct
@firedept35 tor, you should definitely know better. For the record, I'm with a fire department in the suburban New York area, but fire is fire; it doesn't go easier on you just because your from the rural south or the urban north.
Its not a flashover, too much force coming from it.
Most likely a fire smoke explosion like you said which are very similar to backdraughts but have a different ignition, e.g an burning ember. so with the water stopping it would allow a pyrolising object to ignite and cause the deflagration.
@firedept35 whaha thats definitely not an flashover :P ive seen flashovers and flashovers doesnt explode backdraft does all u see is smoke not fire than at the suddenly the ladder stopped and the fire got a change of oxygen which causes the backdraft
Easy man. This could have been a backdraft if the fire started on the second floor and then suddenly broke through to the available O2 on the bottom floor. Notice that the blast came from the bottom opening. I'm not saying I'm an expert but the force of the blast seems to indicate backdraft. Someone please let me know if I am wrong.
"A smoke explosion requires a relatively cool mixture of fuel (smoke) and air within its flammable range to come into contact with a source of ignition. On the other hand a backdraft requires introduction of air to an hot, extremely ventilation controlled fire where the concentration of gas phase fuel (smoke) is high and oxygen concentration is low. Both result in an explosion, but the initiating event and indicators ... are considerably different."
@anon01111, ok. Backdraft is when all the oxygen is burnt up in the room and the fire is dying out and there is no vetilation at all. When you get fresh air into that room the fire will blow back at you. So if flames are already coming out of this structure then its ventalated already and has freash air coming in at all times SO ITS NOT A BACKDRAFT. We had a very long disgustion at my Fire Science Class about this video and we had instructors who been on this job for over 50years
@anon01111 Great description- The only thing I would add is the backdraft is in an enclosed area and occurs when vented.
The smoke explosion has a supply of O2 already there when it finds that ignition source. Both can be deadly. I also agree with I have X years....2 SFFD guys just died in a flashover and they were early 50's and late 40's...can happen to any of us.

@anon01111 years both of them said its a flashover. When the room gets to a specific temp. all the objects will explode resulting in a flashover. The water was cooling the fire off, THE NEWS CASTER said they took water off just for a second giving the fire time to build up in temp. and causing a flashover. This is a flashover not a backdraft end of discussion.
@firedept35 :-) "backdraft is when a dying fire gets fresh oxygen from a opening door " so you work at firedept? :-)) As anon01111 said - "just because someone has "X years of experience" doesn't mean they know it all." Just try a simple thing - google out the two terms and you soon find out you've just switched the meanings.
@firedept35 This is not a flashover. This is clearly a backdraft, or more likely a source of explosive igniting. Flashovers do not explode, nor do they cause such force in the surrounding area. Flashover is a simultanious ignition of all combustible material in a compartment. Basically, everything that can catch fire, catches fire.
Notice how the smoke begins to roll and has much less of a push out the opening as it did? Notice the huge color change in the smoke from dark grey to light brown.
Its a flash over its when the smoke explodes, A backdraft is when a fire is starved of oxygen, and it gets air that causes the explosion, this isnt a backdraft,, what cased the explosion here is the build of dangours gases caused by the buildings contents.
A flashover is the near simultaneous ignition of all combustible material in an enclosed area. When certain materials are heated they undergo thermal decomposition and release flammable gases. Flashover occurs when the majority of surfaces in a space are heated to the autoignition temperature of the flammable gases
backdraft is a situation which can occur when a fire is starved of oxygen; consequently combustion ceases but the fuel gases and smoke remain at high temperature. If oxygen is re-introduced to the fire, eg. by opening a door to a closed room, combustion can restart often resulting in an explosive effect as the gases heat and expand
this can't be a backdraft. Backdrafts are caused when the fire is starved of oxygen in a room. The backdraft occurs when oxygen rushes back into the room feeding the fire. Causing the fire to rush out. But on this vid, there was no windows in the building so the fire couldnt be starved of oxygen
We discussed this as a crew. It's backdraft, not flashover. Note how dark and pressurized the smoke is. Flashovers burns cleaner, more complete combustion all of a sudden, and is not an explosion. The density and blackness of this smoke means very incomplete combustion, i.e. starved for oxygen, the condition necessary for backdraft.
Look up the definition of smoke explosion...it is not a BD or a FO. The term SE and BD are used interchangably, but the they have very different definitions. Also if this was a terrorist fire it has nothing to do with explosive charges. Look how the smoke starts to "breath and belch out". There is obviously air to the fire and venting itself...hence a SE.
This was reported as a terrorist explosion, explosives within the structure ignited which caused the explosion. DON"T BEAT ME UP! thats the information that was conveyed during a tv broadcast
I love how we're all experts from a one minute vid....my guess is a BLEVE or rapid container failure of a large quantity of something inside...but that's just a guess. I'm smart enough to realize I don't have enough info to be smart enough....and smart enough not to call my brothers silly names.
This is neither a backdraft or a flashover, it is a perfect example of something known as a delayed backdraft. Due to the gases within the compartment being super heated they expand outward through the opening, being very rich they take time to mix and warm the oxygen in the atmosphere outside the opening till it all reaches the ideal mixture and hits it's flash point at which they ignite in the same way a jet engine does to produce thrust, not an explotion. Trogman 12 you are a clown.
For one, I havent heard much about delayed backdrafts, for two isnt the definition of a flashover that a flashover occures when super heated gases within the thermal layering reach thier ignition temperature all at the same time producing a violent eruption of flame? Basically what you just said, and for three WTF did I do to you, if you dont like my comment, fine, doesnt mean you have to drop to the level of b00shdag down there.
Do you not understand the concept that a backdraft MUST NOT be self ventelated to be considered a backdraft? Man seriously you could correct me if I was wrong, but you are obiously not a respectable firefighter.
This is actually a flashover, not a backdraft. A backdraft happens when oxygen is rapidly introduced into a smothered fire, such as opening a door into a sealed room that contains fire. A flashover like this is when all of the combustable material within the fire reaches its ignition point simultaniosly. The way you can tell its a flashover is that the fire is obiously ventilated and already has plenty of oxygen before it explodes.
You get a "Backdraft" when the fumes from the fire(gas) mixture with air is in an perfect combination, the gases ignites. No different on "typical" black-smoke fumes or propan fumes, the explotion is the same, but it may be need different "mixtures to ignite. Here ti explotion is caused by lots and lots of dark smoke and fresh air streamin´in in the bottom of openings. windows,dores etc..
What do you expect? these so called "firefighters" have minimum, if any training at all......this took place in Peru (South America) where there's NO money for all volunteer fire dept.
One major sign of a backdraft is smoke being sucked into the building and then pushed out. This goes on untill O2 is introduced which then will cause an explosion... This is a plastic factory. It looks to me that this is simply a chemical explosion.
Backdraft!! if you look closely at the video the smoke coming from the second story windows and the first story is completely different. First floor is yellowish brown which is a distinctive warning sign of an impending backdraft, and the second is thick black smoke. The fireball only comes out of the first floor too
Hey all this is actually a smoke explosion. A backdraft occurs when a superheated atmosphere has O2 infused into it after it has consumed most of the O2. It then blows. A flashover is when everything heats to ignition in an active burning area or room. A SE is what happens here- you have an area of smoke that gets to the right temp, O2 mixture and then finds an ignition source and then you have a violent explosion, just as you would have if you had a room full of a combustible fuel (gas, LP)
To correct some ppl, This is actually a flashover. As you can see by the footage the premise is billowing thick clouds of black smoke and the Aerial water stream is being fired through an open window. What you are seeing is what happens when everything in a given area reaches auto ignition point and the gas & oxygen mixture in the smoke reaches ignition point. Hope that clears it up a bit.
You obviously haven't taken flashover class.

I have no way of knowing what caused this, but I do know that plastics factories can have a surprisingly high risk of explosion, depending on what they are making. The raw plastic they put in the molds can range from grains the size of a marble to the consistency of flour. It's the latter that can be a problem if the particles are allowed to become suspended in the air. It's similar to what can cause grain silos to explode. Certain types of pigment used to color the plastic are even worse.

dackdraft can also occur when a fire is smothered out by its own smoke (the smoke gets too thick for a sustainable amount of air to penetrate)

@firedept35 Well mr science. To wake you up. They might have kicked in a window that causes ventilation. This may have caused the large outflow of unburned pyrolyse products. This ain't a flashover.. The closest thing that would be is a smokegasexplosion or a high pressure backdraft (caused by to much + pressure)
Another thing. Even with area's where oxygen flows in, it is possible to create a backdraft, so what you just said about it cant be a backdraft is total bullshit

OK 1, its not a flashover Cenobyte78, sorry. Maybe somewhere in the building there was, but not there. 2. There is a difference between a backdraft, and a smoke explosion, usually you can't tell, but in this case, notice the smoke. It was what you would call 'breathing'. When smoke exits, it creates a vacuum that pulls air in but with a backdraft, it also pulls smoke back in sue to the lack of air. This is why it may be a backdraft. Now, to be a smoke explosion, the smoke must rapidly catch fire

this is no backdraft. to have a back draft you need a closed off space with little to no flame then a suddent rush of oygen to ignite the fumes. this is either a smoke explosion or flashover. the smoke didnt really seem black enough to be a smoke explosion but its possible

@firedept35 < that was neither flashover nor Backdraft. That was a chemical explosion from the barrels of solvent on the bottom floor.

@firedept35 , Well, it's definitely not a backdraft; firedept35 gave the correct definition of one. tubesteakdynamo, I'd be interested to know where you got your information that solvents on the bottom floor ignited. It looked like fire came from both the first and second floors to me, and that the smoke hid the fireball from the second floor from the view of the camera. This is all just speculation though. I'd also be interested to know why you would insult a fellow firefighter. As an instruct

thecartoonhero87 1 year ago
@firedept35
Its not a flashover, too much force coming from it.
Most likely a fire smoke explosion like you said which are very similar to backdraughts but have a different ignition, e.g an burning ember. so with the water stopping it would allow a pyrolising object to ignite and cause the deflagration.
It definately gives the same result

Easy man. This could have been a backdraft if the fire started on the second floor and then suddenly broke through to the available O2 on the bottom floor. Notice that the blast came from the bottom opening. I'm not saying I'm an expert but the force of the blast seems to indicate backdraft. Someone please let me know if I am wrong.
vonskinnyfish 1 year ago
@firedept35
"A smoke explosion requires a relatively cool mixture of fuel (smoke) and air within its flammable range to come into contact with a source of ignition. On the other hand a backdraft requires introduction of air to an hot, extremely ventilation controlled fire where the concentration of gas phase fuel (smoke) is high and oxygen concentration is low. Both result in an explosion, but the initiating event and indicators ... are considerably different."
So it's a backdraft.
anon01111 1 year ago
@anon01111, ok. Backdraft is when all the oxygen is burnt up in the room and the fire is dying out and there is no vetilation at all. When you get fresh air into that room the fire will blow back at you. So if flames are already coming out of this structure then its ventalated already and has freash air coming in at all times SO ITS NOT A BACKDRAFT. We had a very long disgustion at my Fire Science Class about this video and we had instructors who been on this job for over 50years
firedept35 1 year ago
@firedept35 ... a backdraft/ smoke explosion is just a special case of a flashover.
A backdraft is an "over rich" flashover, which ignites after oxygen is introduced into an over rich fuel/air mixture that's above its ignition temp.
A smoke explosion is a "delayed flashover", where cool smoke is ignited by an ignition source.
Further more, just because someone has "X years of experience" doesn't mean they know it all. As an instructor, I run in that attitude all the time.
anon01111 1 year ago 15
@anon01111 Great description- The only thing I would add is the backdraft is in an enclosed area and occurs when vented.
The smoke explosion has a supply of O2 already there when it finds that ignition source. Both can be deadly. I also agree with I have X years....2 SFFD guys just died in a flashover and they were early 50's and late 40's...can happen to any of us.

@anon01111 years both of them said its a flashover. When the room gets to a specific temp. all the objects will explode resulting in a flashover. The water was cooling the fire off, THE NEWS CASTER said they took water off just for a second giving the fire time to build up in temp. and causing a flashover. This is a flashover not a backdraft end of discussion.

@firedept35 :-) "backdraft is when a dying fire gets fresh oxygen from a opening door " so you work at firedept? :-)) As anon01111 said - "just because someone has "X years of experience" doesn't mean they know it all." Just try a simple thing - google out the two terms and you soon find out you've just switched the meanings.
harvestercz 1 year ago
@firedept35 This is not a flashover. This is clearly a backdraft, or more likely a source of explosive igniting. Flashovers do not explode, nor do they cause such force in the surrounding area. Flashover is a simultanious ignition of all combustible material in a compartment. Basically, everything that can catch fire, catches fire.
Notice how the smoke begins to roll and has much less of a push out the opening as it did? Notice the huge color change in the smoke from dark grey to light brown.

Its a flash over its when the smoke explodes, A backdraft is when a fire is starved of oxygen, and it gets air that causes the explosion, this isnt a backdraft,, what cased the explosion here is the build of dangours gases caused by the buildings contents.
kd84afc 1 year ago
A flashover is the near simultaneous ignition of all combustible material in an enclosed area. When certain materials are heated they undergo thermal decomposition and release flammable gases. Flashover occurs when the majority of surfaces in a space are heated to the autoignition temperature of the flammable gases
bobsasleep 1 year ago
backdraft is a situation which can occur when a fire is starved of oxygen; consequently combustion ceases but the fuel gases and smoke remain at high temperature. If oxygen is re-introduced to the fire, eg. by opening a door to a closed room, combustion can restart often resulting in an explosive effect as the gases heat and expand
bobsasleep 1 year ago
this can't be a backdraft. Backdrafts are caused when the fire is starved of oxygen in a room. The backdraft occurs when oxygen rushes back into the room feeding the fire. Causing the fire to rush out. But on this vid, there was no windows in the building so the fire couldnt be starved of oxygen
DanFairbridge21 1 year ago
This has been flagged as spam show
We discussed this as a crew. It's backdraft, not flashover. Note how dark and pressurized the smoke is. Flashovers burns cleaner, more complete combustion all of a sudden, and is not an explosion. The density and blackness of this smoke means very incomplete combustion, i.e. starved for oxygen, the condition necessary for backdraft.

Look up the definition of smoke explosion...it is not a BD or a FO. The term SE and BD are used interchangably, but the they have very different definitions. Also if this was a terrorist fire it has nothing to do with explosive charges. Look how the smoke starts to "breath and belch out". There is obviously air to the fire and venting itself...hence a SE.

This is neither a backdraft or a flashover, it is a perfect example of something known as a delayed backdraft. Due to the gases within the compartment being super heated they expand outward through the opening, being very rich they take time to mix and warm the oxygen in the atmosphere outside the opening till it all reaches the ideal mixture and hits it's flash point at which they ignite in the same way a jet engine does to produce thrust, not an explotion. Trogman 12 you are a clown.
sfly5 2 years ago
For one, I havent heard much about delayed backdrafts, for two isnt the definition of a flashover that a flashover occures when super heated gases within the thermal layering reach thier ignition temperature all at the same time producing a violent eruption of flame?

Trogman12 2 years ago
This is actually a flashover, not a backdraft. A backdraft happens when oxygen is rapidly introduced into a smothered fire, such as opening a door into a sealed room that contains fire. A flashover like this is when all of the combustable material within the fire reaches its ignition point simultaniosly. The way you can tell its a flashover is that the fire is obiously ventilated and already has plenty of oxygen before it explodes.
Trogman12 2 years ago
You get a "Backdraft" when the fumes from the fire(gas) mixture with air is in an perfect combination, the gases ignites. No different on "typical" black-smoke fumes or propan fumes, the explotion is the same, but it may be need different "mixtures to ignite. Here ti explotion is caused by lots and lots of dark smoke and fresh air streamin´in in the bottom of openings. windows,dores etc..

One major sign of a backdraft is smoke being sucked into the building and then pushed out. This goes on untill O2 is introduced which then will cause an explosion... This is a plastic factory. It looks to me that this is simply a chemical explosion.

boostnsupra101 2 years ago
Hey all this is actually a smoke explosion. A backdraft occurs when a superheated atmosphere has O2 infused into it after it has consumed most of the O2. It then blows. A flashover is when everything heats to ignition in an active burning area or room. A SE is what happens here- you have an area of smoke that gets to the right temp, O2 mixture and then finds an ignition source and then you have a violent explosion, just as you would have if you had a room full of a combustible fuel (gas, LP)
ffmed74 2 years ago
To correct some ppl, This is actually a flashover. As you can see by the footage the premise is billowing thick clouds of black smoke and the Aerial water stream is being fired through an open window. What you are seeing is what happens when everything in a given area reaches auto ignition point and the gas & oxygen mixture in the smoke reaches ignition point. Hope that clears it up a bit.
