When hoisting a portable ladder to the roof, how far from the end of the rope should the bowline knot be tied?

When hoisting a portable ladder to the roof, the bowline knot should be tied 9 feet from the end of the rope to ensure safe and effective lifting. This distance is optimal because it provides sufficient length for handling the rope while maintaining control over the descent of the ladder. The 9-foot measurement allows firefighters to have enough rope to secure the ladder while ensuring that the knot is at a height that helps prevent it from getting caught or tangled during the hoisting process. This distance also aids in properly positioning the ladder for safe placement on the roof.

Choosing an incorrect distance could lead to difficulties in maneuvering the ladder or insufficient rope to maintain control, potentially leading to safety issues during operations. The 9-foot guideline is a standard practice aligned with safety protocols within fire service operations.
