What gauge pressure must be maintained while the fire apparatus is moving for pump-and-roll operations?

For pump-and-roll operations, it is essential to maintain appropriate gauge pressure to ensure adequate water flow and pressure while the fire apparatus is in motion. A pressure of 80 psi is typically regarded as the standard for these operations, allowing for effective firefighting while the apparatus is moving. This pressure ensures a stable water supply sufficient for operation, optimizing performance and ensuring safety.

Maintaining this level of pressure helps maximize the effectiveness of the water stream while allowing the vehicle to maneuver effectively. Additionally, it strikes a balance between sufficient water flow and control over the apparatus, which is critical during dynamic fireground situations where both precision and responsiveness are necessary.
