What is the primary goal of using positive pressure ventilation during firefighting operations?

Using positive pressure ventilation during firefighting operations primarily aims to create a safe environment for both firefighters and potential victims trapped inside the structure. This technique is designed to remove heat, smoke, and other hazardous gases that accumulate due to combustion. By pressurizing the interior of the building and forcing smoke and hot gases out through strategically placed openings, positive pressure ventilation effectively lowers the overall fire load and improves conditions, allowing for safer access for firefighting personnel and facilitating potential rescues.

The method enhances visibility inside the structure, but this is a secondary effect rather than the primary goal. Cooling surrounding areas can be a moderate consideration, but the main focus remains on clearing the atmosphere to make it less dangerous for operations. Similarly, while dissipating toxic smoke is important, it acts in conjunction with the primary objective of establishing a safe environment where firefighters can perform their duties effectively and safely.
