In an airtight room when there is a fire it consumes the oxygen and becomes ventilation controlled the room gets hotter and hotter and the combustible solids in the room continue to pyrolyze into flammable gasses but can’t burn because there is no oxygen. Then a firefighter opens the door…
There’s actually a vacuum in the room, it sucks fresh air in and all those flammable gasses and smoke ignite and explode.
It’s called a backdraft. It only happens when there is a tightly sealed home/room.
If there is a fire in in a air tight room and you close the door and stop the ventilation, wouldn’t the fire die out because of the lack of oxygen?

Depending on how air tight it is, couldn’t it make the room explode due to the increased pressure from the hot gasses expanding?
