What is a cross-lay?

• A. A Pre-Laid Supply Line Laid Across the Floor to Speed Deployment
• B. A Type of Nozzle Adjustment
• C. A Secondary Water Supply to Hydrant
• D. A Hose Storage Method

Answer: (A)

A cross-lay is a pre-connected hose line that’s laid out in advance so it can be deployed quickly to deliver water. It’s usually arranged to cross the floor or pass through a doorway from the engine to the interior, so once the crew opens the nozzle, water can be flowing almost immediately without having to couple hoses on scene. This makes the initial attack faster and more efficient, especially in the fast-moving early phase of a fire. It’s not about adjusting a nozzle, isn’t a secondary hydrant supply, and isn’t simply a hose storage method—the defining idea is a ready-to-use line laid out to speed deployment.
