By opening a large hole in the roof heat and smoke can quickly be removed from the structure. This rapidly improves conditions inside the building, hastening fire suppression.

What does venting a roof do in a fire?

When a hole is made in the roof, the smoke and gases escape. Venting the roof makes it easier for firefighters to see and find the source of the fire, and it also reduces the possibilities of backdraft and flashover.

Why is ventilation important in firefighting?

Simply put, we ventilate fire to improve interior conditions and to reduce the chances of getting people (citizens and firefighters) hurt or killed. The most severe event we face from fire is flashover, and ventilation needs to be a priority to reduce the likelihood of this occurring.
