What is the first step in developing a pump chart?

The first step in developing a pump chart involves identifying all nozzles, devices, and layouts used by the department. This step is crucial because it provides a comprehensive understanding of the operating environment and the various equipment that will affect pump performance.

By cataloging all nozzles, devices, and layouts, the operator can determine the specific flow requirements and pressures needed for different firefighting scenarios. This foundational knowledge guides decisions on how to prioritize water supply, manage pump pressures, and ensure efficient operation during fire suppression efforts.

The development of an effective pump chart depends heavily on this initial understanding, as it sets the stage for assessing flow rates, water source availability, and the specifications of the pump. Without this step, the chart may not accurately reflect the needs of the firefighting apparatus, potentially leading to challenges during critical operations.
