The practice of cutting holes in the roof of a burning structure is known as ventilation. Ventilation helps firefighters inside the building by allowing smoke and superheated gases to escape, which eliminates some of the smoke in a building and makes the environment a little easier to work in, in addition to keeping the superheated gases from igniting an attic fire. Unlike the movies, it is normally pitch-black inside a burning building because of all the smoke. Ultimately, ventilation helps firefighters who may be searching for someone trapped in the building by eliminating some smoke and heat, or those who are trying to put the fire out by allowing hot steam to escape rather than come back at them and burn them. This helps us save people who may be trapped, and to put the fire out quickly, saving more of the building.
