What is the purpose of a forward lay in water supply?

• A. To lay hose from the scene back to the hydrant.
• B. To practice laying hose without connecting to a source.
• C. To bring the supply hose from the first arriving engine to the incident scene; a forward lay moves water toward the scene from the source.
• D. To relocate the water supply after the incident.

Answer: (C)

The key idea is delivering water to the fire efficiently by arranging the water supply hose from the hydrant toward the scene. In a forward lay, the supply hose is brought from the hydrant to the incident, so water moves toward the scene from the source and can be pressurized into the attack engine quickly. This setup lets the first arriving engine begin applying water to the fire without waiting for a long run of hose back toward the hydrant. It contrasts with laying hose from the scene back to a distant hydrant, which delays getting water to the nozzle.
