Part 3 of 7: (Fire Dynamics) NIST & UL Research on Fire Behavior & Fireground Tactics 

H factor would be like wind chill, only instead of sucking it away, it is juicing you up..... In the Southwest USA, the sun is hitting you at 3kw per meter in the summer.....

2:07 - Fires do not require oxygen. This is less applicable to residential fires, but a variety of common industrial chemicals, such as acetylene, will combust spontaneously when in the presence of a chemical which can accept electrons like the halogens.

FDIC Science In The Big Room

3:33 Gaseous fuel and Pressure! 12:20 Just about every room in a house has a window. If you have 1300 degrees at the ceiling you do Not want to go into that room to cool it down and extinguish the burning material. You break out the sashes in the fire room windows from the safety of outside and hit the ceiling with a straight stream and wave it around. The hot gasses which are under pressure will explode out the window and the instant application of water will eliminate the flames in 2-3 seconds and soak the burning material in 3-5 seconds. All the gaseous material will go right out the window. THEN, you go into a Much safer interior to mop up. Even or especially if there are victims inside, you do the same thing exactly. Would you want to be laying on the floor with 1800 degrees right around the corner? 13:28 That's why you want the windows out in the fire room so all that hot gas will go directly outside not through the house. If you can see the BM through the window, then you can put it out without having to go in. There is No reason for that guy to be in there before the fire is extinguished from the outside. 17:35 There shouldn't be a fire fighter in there in the first place. That room can be vented and extinguished through the window and door. 18:45 The flames are Not moving toward the source of oxygen!!! The gasses are igniting due to a constant supply Of gasses and the fresh air coming in the door. They are moving toward the door because Pressure is building up and it is Releasing out the open door. Flames do Not go looking for oxygen. They have a very Low IQ and can't think that far ahead. This was a pretty much Useless video as it was full of useless science and nothing about Safe and Fast gas venting and fire suppression. Stop talking and just put the fire out!
