    Study Notes

    Hydrant Kit Bag

    • The hydrant kit bag is stored in the right rear compartment of the apparatus.
    • The kit bag contains:
      • 2 x 65mm gate valves with 100mm Storz adapters
      • 1 x hydrant wrench
      • 2 x spanner wrenches
      • 1 x dead blow hammer

    Forward Lay

    • In a forward hose lay, hose is deployed from the water source to the incident.
    • The firefighter connects to the hydrant while the apparatus proceeds to the fire.
    • Disadvantages of forward lay:
      • Friction loss becomes an issue in the supply line as flow rates increase.
    • Steps for forward lay:
      • Apparatus stops at the hydrant, firefighter exits, and retrieves the hydrant kit bag.
      • Firefighter lays the hose down and folds it back onto itself, making a bight.
      • The hose is secured against the barrel of the hydrant with the toe of the firefighter's boot.
      • Signal is given to the apparatus driver to 'LAY HOSE'.

    Reverse Lay

    • In a reverse hose lay, hose is deployed from the incident scene to the water source.
    • Advantages of reverse lay:
      • Decreases friction loss from the hydrant to the apparatus.
      • Easier to connect multiple supply lines from the hydrant to the apparatus intakes.
    • Steps for reverse lay:
      • Firefighters remove tools and equipment from the apparatus before it proceeds to the water source.
      • Pump operator begins supplying attack lines, then secures their own water source.

    Split Lay

    • In a split hose lay, supply hose is dropped by an apparatus and connected to by another apparatus.
    • Commonly used in:
      • Dead-end streets
      • Industrial/commercial complexes with private water supply
      • Long access roads/driveways
    • Steps for split lay:
      • Apparatus stops at a designated location, firefighter exits, and removes 15m of 100mm supply hose.
      • Second arriving apparatus arrives, firefighters exit, and connect to the dropped supply hose.
      • Firefighter connects the 100mm hose from their apparatus to the dropped supply line.
      • Pump operator secures the water source and coordinates relay pump operations.
