How does a doughnut hose roll differ from a straight hose roll?

The doughnut hose roll is characterized by the way it accommodates hose couplings, making the couplings easily accessible for quick deployment. In this type of roll, both couplings are positioned on the outside of the roll rather than being enclosed within the roll itself. This design allows firefighters to quickly connect the hose to a water source or other hoses without needing to unroll the entire hose, thereby enhancing efficiency during operations.

In comparison, a straight hose roll typically contains couplings within the center of the roll. This can make access to the couplings slower and more cumbersome, as firefighters may need to unfold or unroll a portion of the hose to connect it, especially in a situation where time is of the essence.

The unique arrangement of the couplings in the doughnut roll contributes to its practical application in firefighting, where every second counts, and quick access to equipment is crucial for effective emergency response.
