What is the maximum speed at which the transmission should be shifted into drive for pumping?

The maximum speed at which the transmission should be shifted into drive for pumping is set at 15 mph for several important reasons that relate to operational safety and efficiency during firefighting operations.

Shifting into drive at this specific speed helps ensure that the vehicle's pump engages smoothly, minimizing potential mechanical strain. Being at a controlled speed allows the driver to maintain better control of the vehicle, which is essential when navigating through potentially hazardous environments, such as those encountered at emergency scenes. Additionally, engaging the pump while the vehicle is moving too fast could lead to excessive strain on the pump components, jeopardizing both equipment reliability and operational effectiveness.

Operational protocols often dictate specific speed limits to ensure that firefighters can safely manage both the vehicle and the work being performed, which includes managing hose deployment and maintaining stability. Adhering to the guideline of shifting at or below this speed helps to ensure the safety of all personnel involved and maximizes the effectiveness of the firefighting efforts.
