A ______ lay results when hose is unloaded at the scene of a fire and the pumper proceeds to the water source.

• A. Forward
• B. Direct
• C. Combination
• D. Reverse

Answer: (D)

This describes a reverse lay. In a reverse lay, the supply hose is unloaded and laid at the scene first, while the pumper then proceeds to the water source to connect to the hydrant. Once water is connected, it is pumped back through the already-placed supply line to the scene. This approach can speed up getting water to the scene when distances or access make it practical to position the engine away from the hydrant and have the hose ready at the location of the fire. In contrast, a forward lay would have the engine go to the hydrant and lay the hose toward the scene as it travels, with the pump brought close to the water source.
