This 2002 video graphically demonstrates the growth of fire in an office and the possible impact on companies and staff. A longer version on DVD is available from www.BREBookshop.com
It's called pyrolysis, the paper isn't on fire. The heat in the room is so intense it forces vapor out of the paper and ignites that. Clever stuff that fire :)
Vintage production! These days there would be a few lines about a VPN provider and a reminder to smash the like button and don't forget to subscribe! ;)
That void area above the ceiling is a perfect tunnel for the heat to radiate to other parts of the structure... so a small fire even if brought under control by the fire personal coula have started another fire somewhere else in the building and can go unnoticed for a long time.
If this video doesn't scare a person into taking fire safety seriously then nothing will. Incidentally, another thing that would help in this type of situation would be a fire suppression system such as a sprinkler system. A working sprinkler system would for the most part saved that office.
NOTICE!!! When the first firefighter started applying water high up at the flames and smoke, the fire just continued unabated. When water was trained on the burning material, the flames went out Instantly.
That didn't spread as fast as I thought it might, and the fire rolled over but the room never really flashed. I wonder if having one side completely open allowed the heat and gasses to escape and limited the thermal input on the rest of the room.
Мисля пожар се предизвиква от безотговорно несериозно отношение на охраната - пожар. Пожар толкова бързо се разраства, че е трудно да се гаси.... Благодаря, интересно, поучително видео!
Because smoke is unburned gases, meaning it could catch fire at the right temp. this can also cause a backdraft, say that this office was poorly ventilated with all doors and windows shut, When the fire started it would burn until oxygen became limited then you will get heavy Blackish/yellow smoke and if you was on the other side of that office in the hall or something, you would see blackish/yellow smoke puffing from the cracks of the door and it will literally look like the room is breathing it will poof it in and out in a breathing motion...then when someone opens the door to investigate BOOM backdraft...all of the Smoke and unburned gases will ignite violently because the oxygen going into the room feeding the fire. -Andrew Thomas-Manchester fire department-auxiliary firefighter
i think this would be a better example if you did not have an openning feeding the fire as it travelled over the ceiling and fed the fire , now i could be wrong yet thank you for the information
This is interesting, but surely it can only be so realistic without a 4th wall? Such a fire in a fully enclosed space would have quite a different outcome I suspect - and with heat bouncing and radiating off the missing 4th wall, I think flashover would occur much more quickly than is seen here.
Well, I think that would depend on how much oxygen was available in the room to start with, but either way, this is not a realistic test without a 4th wall.
tjf4375 But the thing is... it's not a realistic video, because most office buildings now have built in fire things, that would put out the fire. I still think the coolest one is a CO2 because it deprives the fire of one thing, O2.
No, breaking the 4th wall is something completely different - that means when an actor talks directly to camera (which is normally where the 4th wall would be) while they are filming on set. What I'm saying is that they needed to build a 4th wall here, because they are demonstrating something whose behaviour would be affected by the radiant heat reflected by it.
I’ve just been doing fire warden training and they used this video. Very educational, but there’s a niggling thought in my brain. I recognise the narrator, but cannot for the life of me find his name 😱 This is gonna bug me all day!!!
Fires can destroy a home and lives. They can cause massive amounts of destruction and kill people who are caught by either the flames or the smoke. If you survive such a horrible thing, you are likely to go through the stress and pain of rebuilding. It is especially difficult if you lost someone close to you. To avoid all of this, you need something that works. You need to fireproof your home with available coatings that are safe as well as effective. This will give you the chance to lower the risk as fire and contain any that do occur. With how dangerous fires can be, there is no reason not to do this. A fire retardant spray or paint will help to protect your home quite a bit. These will reduce the risk of a spreading fire, allowing you to escape and control the flames. If something does happen, like if there is a sudden fire in a single room, there will be less of a chance of it spreading. You will be more likely to survive the fire as well as stop it before it caused any major destruction. These are effective options and they can give you the chance to save yourself in many ways.
While the room itself could be made with concrete, the furniture cannot. Humans normally do not want to sit on naked concrete all day while working. Furthermore, most offices have lots of paper lying around.
What is the temperature of the radiant heat 6' away from the rooms exit door at the floor level where a victim might be? If the room was hit by a Heavy SPRAY of water through a window and instantly soaked all the interior material, what would be the temperature at the floor in the hallway? What would be the radiant heat temperature from the "Steam" created by the large amount of water, at the floor? How long would a flame be "Pushed" through the door by the spray before the flame was extinguished by the large amount of water? The answers will go a long way towards deciding which is better, waiting an eternity for firemen to find the victim while the fire rages and the effect on the victim if the room is hit by a large blast of water before the rescue.
Simple, if you listen to what the voice over man actually said, he said at this time they would have gone off, which says they have none. Its a demo anyway.
bluecylinder Not with the ongoing hours people are made to work nowadays so that the company can keep raking in profit especially at offices employers do not care about the home life of thier employees or certain hours of the day anymore they care about as much profit as possible everyday! Stay and work or get fired!
