Which combination of knots is typically used to hoist a hose line?

The combination of knots typically used to hoist a hose line is the clove hitch and half hitch. The clove hitch is particularly effective for securing the hose to a specific point, such as a ladder or a pole, because it provides a firm hold and allows for easy adjustment and removal. This knot can be tied around the hose without needing to unroll it entirely, making it practical for quick deployments in emergency situations.

The half hitch complements the clove hitch by providing additional security once the hose is hoisted. It is often used to further stabilize the load and prevent any slipping that might occur after the initial securing with the clove hitch. This combination of knots ensures that the hose remains secure during the hoisting process, allowing firefighters to maintain a focus on their tasks without worrying about the equipment coming loose or falling.

Other combinations might not offer the same level of security or practicality for specifically hoisting hose lines. For example, the bowline creates a fixed loop, which is not as adaptable for quick adjustments when securing a hose, and may not be necessary in this context. Therefore, the clove hitch and half hitch stand out as the most suitable choice for this application.
