Study Notes

Water Supply Operations

The first engine at a fire scene is responsible for laying an initial attack line and securing a water supply, while the second engine lays a back-up or second line of equal or greater size and type as the initial attack line.

Securing Water Supply

In certain situations, the first engine may direct the second engine to secure a water supply for the initial attack engine, which must be confirmed by radio communications.

Water Supply Methods

Front suction on the first arriving engine:
- Engine stops within 100' of the fire hydrant.
- Driver/operator uses the 50' front suction and/or additional LDH sections to complete the water supply connection.
LDH pulled from rear of the first arriving engine:
- Engine stops not within 125' of the fire hydrant.
- Driver/operator pulls up to 200' of LDH to complete the water supply connection.
Reverse lay using the LDH off the second arriving engine:
- First engine stops in front of the incident and is not within 125' of the fire hydrant.
- Second engine is given the water supply assignment.
- Second engine drops its LDH hose at the first engine and reverses out to the fire hydrant.
- LDH can be connected directly to the fire hydrant or connected to the hydrant and relay pumped to the first engine.
Forward lay using the LDH off the first arriving engine:
- First arriving engine stops at a fire hydrant before the incident scene.
- Jump Seat Firefighter or Ambulance Passenger gets out and pulls the LDH to complete the hydrant wrap.
- Engine is driven forward, deploying the LDH as it moves to the incident scene.
- LDH is connected to an intake of the engine to prepare to receive water from the second engine.

Key Definitions

LDH: Large Diameter Hose
Forward Lay: Hose laid from the water source to the fire
Reverse Lay: Hose laid from the fire to the water source
Looped Hydrant: Process of using a commercial strap attached to the end of the LDH to lead out the LDH from the hose bed.
