Why do firefighters break windows in a burning building?
As mentioned in the statement above, dangerous superheated gases need to be ventilated to allow firefighters to safely and quickly rescue trapped occupants and extinguish the fire. By venting the window of a room that is on fire, it actually helps to contain the fire within that room of origin. Otherwise heated gases spread throughout the inside of the house. Breaking the window really prevents a great deal more damage than it appears to cause.
