Which of the following can be used to aid in the coupling and uncoupling of hose?

Rocker lugs are specifically designed to facilitate the coupling and uncoupling of hoses. They have a unique shape that allows for easier manipulation when connecting or disconnecting hoses during firefighting operations. The design of rocker lugs provides a solid grip and aligns the coupling mechanism effectively, enabling firefighters to work efficiently, even in stressful or low-visibility situations.

In the context of other options, while Storz lugs and spanner lugs can assist with hose connections, they serve different purposes. Storz lugs are typically found on Storz couplings and are designed for a specific locking mechanism that doesn't require twisting, whereas spanner lugs refer to specialized tools used to tighten or loosen hose fittings but are not themselves a part of the coupling design. Wrench lugs are usually associated with equipment and not directly relevant to hose management. This distinction emphasizes why rocker lugs are the most suitable choice for aiding in hose coupling and uncoupling.
