The selection of hose load carried on the pumper is primarily determined by the type and size of fires expected to be encountered. This consideration is crucial for effective firefighting, as different fire scenarios require different levels of water flow and types of attack. For example, a large commercial building may require a different hose diameter and configuration compared to a small residential fire. The expected fire conditions dictate the amount of hose, nozzle type, and pressure that will be needed to effectively combat the fire.

Considering the other factors, while the type of water supply and the experience of the crew can influence hose deployment and tactics, they do not directly dictate the initial selection of hose load. The manufacturer of the pumper also plays a role in the capabilities and configurations allowed, but it is ultimately the fire scenario that drives the need for specific hose loads. Therefore, understanding the anticipated fire types and sizes is key to preparing the equipment necessary for an effective response.
