What should be done if a building's fire pump is operational during a standpipe operation?

When a building's fire pump is operational during a standpipe operation, it is essential to connect to the standpipe and charge the lines to a pressure of 150 PSI. This approach is crucial because the fire pump is designed to supply water at sufficient pressure for firefighting efforts.

Charging the standpipe at 150 PSI ensures that the system is adequately pressurized to deliver water effectively, maintaining a strong flow rate of water for fire suppression. This pressure allows firefighters to operate hose lines efficiently, facilitating better reach and delivering water directly where it is needed most.

Utilizing the building's fire pump while managing the standpipe system in this way supports optimal firefighting operations and ensures the safety and effectiveness of the firefighting team on the scene. It also aligns with standard operational practices regarding the use of pressurized systems in firefighting scenarios, which aim to maximize water delivery while ensuring adequate flow and pressure to combat the fire effectively.
