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.
