    Study Notes

    Water Supply for Fire Mitigation

    • Effective water supply is crucial for incident mitigation; however, it should not delay immediate response actions.
    • "Fast water" through booster tank attacks is prioritized to enhance life safety and fire suppression.
    • Booster tank attacks significantly improve suppression capacity, allowing for flow rates that are effective in residential fires, typically controlling fires with 200 to 300 gallons.
    • With 1,000-gallon booster tanks, a safety factor of approximately 4:1 is achieved, allowing for aggressive fire control and safety assessments for rescues.
    • Early fire control through hoseline deployment leads to reduced fire growth, aligning with the second objective of stabilization.

    Water Supply Algorithm and Plans

    • A water supply algorithm provides multi-step plans (A through D) starting with the booster tank attack.

    Plan A: First-Due Engine Takes Its Own Hydrant

    • If within 200 feet of a hydrant, the first-due engine will establish its own water supply.
    • Engine companies should consider hydrant location for optimal apparatus placement, helping maintain access for truck placement.

    Plan B: Reverse Lay

    • If the first engine cannot reach the hydrant, the second-due engine completes water supply while ensuring better positioning for the truck.
    • Personnel from the second engine exit to prepare for action promptly upon arrival.

    Apparatus Operator Responsibilities

    • Operate in minimal turnout gear while establishing water supply; proceed to hydrant unless relay operation is needed.
    • Maintain pump redundancy by having a pumper at the hydrant ready to support the attacking pump in case of mechanical failure.
    • Advantages of reserve lay include faster personnel readiness, lesser scene obstruction, enhanced flow capacity, and operational redundancy.

    Forward Lay Strategies

    • Forward Lay by Second Engine with Booster Backup: Second-due engine shares booster tank water, increasing total initial water supply to 2,000 gallons while maintaining operational readiness.
    • Forward Lay by First Due Engine: Historically used but causes delays in engine arrival and initial attack line deployment, ultimately reducing overall water supply effectiveness.

    Access to Water Supply

    • Full water supply potential from hydrants depends on their support and operational readiness; unsupported hydrants often limit usable water volume during incidents.
