What is the main purpose of ventilation in firefighting?

The main purpose of ventilation in firefighting is to remove smoke and heat from a structure to improve visibility and safety. Effective ventilation plays a crucial role in managing hazardous conditions during a fire incident. By removing smoke and heated gases, firefighters can enhance visibility, which is essential for navigating the structure and locating victims or the fire itself. Improved visibility allows for safer operations and helps prevent disorientation among firefighters.

Furthermore, reducing heat levels can mitigate the chances of flashover, a dangerous fire phenomenon that occurs when combustibles in the vicinity reach their ignition temperature, leading to extreme fire behavior. Therefore, facilitating the removal of smoke and heat not only aids in firefighting efforts but also significantly enhances the safety of both firefighters and any individuals who may be trapped inside the structure.
