What is the primary purpose of the alternating knees technique in firefighting?

The primary purpose of the alternating knees technique in firefighting is to provide heat relief on hot floors. This technique involves firefighters dropping to one knee while advancing, allowing them to stay lower to the ground and minimize exposure to intense heat that can rise from burning materials. By alternating knees, firefighters are able to take advantage of cooler air closer to the ground and avoid direct contact with extremely hot surfaces, thereby enhancing their safety and effectiveness during firefighting operations.

While other techniques may also promote speed, stability, or reduce fatigue, the alternating knees technique primarily addresses the critical concern of managing heat exposure. This approach not only helps in protecting firefighters but also maintains their operational capacity during high-temperature scenarios.
