What is the purpose of a ventilation hole in firefighting?

The purpose of a ventilation hole in firefighting is to release heat and smoke from a structure during a fire. Creating ventilation holes allows the hot gases and smoke, which can be dangerous to both firefighters and potential victims inside, to escape. This process helps to lower the temperature within the building and improves visibility, making it safer for firefighters to operate. Proper ventilation can also help to control the spread of the fire by reducing the intensity of the conditions inside. When heat and smoke are allowed to escape, it can also prevent the potential for a backdraft, which occurs when fresh air is introduced into an environment that is already heavily charged with heat and smoke. Therefore, the focus of creating a ventilation hole is centered around safety and fire control.
