What does the term "ventilation" refer to in firefighting?

The term "ventilation" in firefighting specifically refers to the process of removing smoke and heat from a burning structure. This process is crucial for improving visibility and reducing the risk of flashover, as it helps to create a safer environment for both firefighters and victims potentially trapped inside. Effective ventilation allows for the release of superheated gases and smoke, enhancing fire behavior control and facilitating extinguishment efforts. Proper ventilation techniques can involve natural methods, such as opening windows or doors, or mechanical methods using fans or other equipment to aid in smoke and heat removal. Understanding ventilation is essential for firefighters to mitigate hazards and improve conditions within the structure being attacked.
