Where should ventilation occur during a fire response?

Ventilation during a fire response is crucial to improve conditions within the structure and to assist firefighting efforts. The primary aim of ventilation is to remove smoke, heat, and toxic gases that accumulate during a fire. By venting as close to the fire as possible, firefighters can more effectively control smoke movement and reduce the potential for flashover, which is a rapid spread of fire due to increased temperatures and the presence of flammable gases.

Ventilating near the fire also helps in creating a more favorable environment for both firefighters and potential victims, allowing for better visibility and reducing the overall heat load. This method enables a more efficient attack on the fire by allowing cooler, breathable air to enter near the fire, while toxic fumes and superheated gases can exit from the same area, facilitating effective fire control and rescue operations.
