No ventilation necessay at that time, it’s seem a little fire in the leaving room

The fire of Terre Haute and the Gary Indiana are two lost fires attack by imcompetent firefighters
anybody can do better than these fireman,not qualify a bit.very sorry
I see the keystonecups to fight a fire.
They are not professional, not wearing their full gear suit and SCBA, the first mission is to oppen the roof,nothing else the only to évacuate the gaz the heat and hot smoke,from the roof and the inside of the house, ready to step in with the rignt flow rate to absorb the heat of the fire and go in to knock down the fire, in on place not in front ,and the side B et in the front
No horizontal ventilation at the beginning, keep the place close ,it’s always the same think on every fire no ventilation, and they opened all door and window. and opening feeds the fire, close the door,dont brake windows pane etc,it’s will be heasy to extinghuish that fire. the most important thing is to make the roof ventilation to eliminated the gas. the heat,and hot smoke from interior and the interior wall and ceiling,all the closes spaces,evacuate to the outside it’s not complicated. do it

Rapid fire progress due to ventilation induced flashover or backdraft is not an instantaneous process. Depending on a number of variables such as the location of the fire, current level of involvement, temperature of the smoke (hot gas) layer, and extent of the increase in ventilation these rapid fire progress phenomenon may take some time to occur. However, when it does, fire development will be extremely rapid! Firefighters entering a compartment or building containing an under ventilated fire must be aware of and manage the hazards presented by the potential for rapid fire progress. Remember, many if not most fires that have progressed beyond the incipient stage before firefighters arrival are ventilation controlled and present the potential for rapid fire progress with increased ventilation (see Situational Awareness is Critical).
