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

The combination of a clove hitch and a half hitch is commonly used to hoist a hose line due to the unique properties of each knot. The clove hitch is excellent for securing the hose to a fixed object, such as a ladder or a pole, because it tightens under load and is easy to untie after use. This makes it particularly advantageous in firefighting, where equipment needs to be secured quickly and effectively during operations.

The half hitch serves as a securing knot that adds extra security to the clove hitch. When applied over the clove hitch, the half hitch helps prevent the clove hitch from slipping, especially when the hose is being lifted or put under tension. This combination ensures that the hose line stays firmly in place during the hoisting process, which is crucial for safety and operational efficiency on the scene.

Thus, when performing tasks that involve hoisting hoses, the combination of these two knots provides both strong security and ease of handling, making it an ideal choice for firefighters.
