Which component is part of creating an effective water supply strategy in firefighting?

In the context of firefighting, creating an effective water supply strategy is crucial for managing and extinguishing a fire efficiently. Initiating the Fire Department Connection (FDC) is an essential part of this strategy because it allows firefighters to quickly establish an additional water supply from a nearby source, such as a hydrant. When faced with a large fire, the initial water supply from fire engines may not be adequate; therefore, having access to the FDC enables firefighters to boost their water flow, ensuring they can effectively combat the flames.

Establishing a command structure, while important for overall incident management, primarily deals with leadership and coordination rather than the specifics of water supply. Coordinating evacuation routes focuses on ensuring civilian safety during emergencies and does not directly relate to water supply. Setting fire behavior patterns involves understanding how fires spread, which helps in tactics and strategy but does not address the logistical element of ensuring adequate water access.

Thus, initiating the FDC stands out as a critical action specifically related to enhancing water supply capabilities during firefighting operations.
