What is a primary purpose of a Box Fan in a firefighting scenario?

In firefighting scenarios, a Box Fan primarily serves to aid in de-smoking by creating pressure areas. This function is crucial because smoke can obscure visibility, hinder rescue operations, and pose serious health risks to both firefighters and victims. By directing airflow out of the structure, the Box Fan helps to remove smoke and toxic gases more efficiently, thus improving conditions for firefighting efforts and victim rescue.

The fan achieves this by creating a pressure differential that encourages cleaner air to enter the space while pushing smoke-laden air out. This is particularly important in situations where smoke accumulates in a confined space; by integrating this technique, firefighters can significantly improve their operational safety and effectiveness. In contrast, while cooling down the area or managing generator operation might be relevant in some contexts, they do not represent the primary use of Box Fans during fire suppression efforts. Similarly, draining water is not the fan's function; its utility lies in air movement and ventilation rather than fluid management.
