Why does the fire department make holes in my roof and break windows?
Fire in a building creates a lot of heat and smoke. In many cases, firefighters must remove the heat and smoke before they can get close enough to put out the fire. Heat and smoke rise, so cutting a hole in the roof and breaking out windows in planned locations allows the smoke to vent upwards, allowing cool air to enter the building from below. This is called “ventilation”. It also improves visibility and lowers heat conditions for the firefighters inside, allowing them to quickly and safely extinguish the fire. Remember, heat and smoke can cause extensive damage; ventilation will actually reduce overall damage to a building and contents.
