What can be used to support a water chute constructed with pike poles?

A stepladder can effectively support a water chute constructed with pike poles because it provides a stable base and height that can help elevate the pike poles appropriately. When creating a water chute, it is essential to ensure that the chute is securely positioned to allow water to flow smoothly and efficiently, minimizing the risk of collapses or spills. The stepladder's structure allows firefighters to position the pike poles at the right angle, leveraging gravity to direct water flow.

Other options do not offer the same level of stability or height adjustment. A phone book lacks the necessary support and stability for a structure meant to handle water flow, while rope binding may not provide the rigidity needed to maintain the chute's shape effectively. A Halligan bar, while useful in firefighting tasks for prying and forcible entry, does not serve the purpose of supporting a water chute in this context.
