What is a critical safety reminder during pump operations?

During pump operations, obtaining permission from command before throttling down if a crew is on line is crucial for ensuring the safety of all personnel involved. This guideline is essential because changing the pump's pressure can significantly affect the water supply and flow available to firefighters working on the line. If a crew is actively engaged in firefighting or rescue operations, reducing the pump's pressure without proper communication can lead to a sudden decrease in the water available to them, potentially putting them at risk.

Maintaining clear communication with command is vital for coordinating effective operations and providing the necessary support to crews in the field. It helps to prevent misunderstandings that might arise from sudden changes in water pressure, ensuring that all personnel are aware of the operational conditions and can adjust accordingly. Therefore, this practice promotes overall safety and operational efficiency during firefighting efforts.
