The appropriate equipment that engine companies should carry for buildings equipped with standpipes includes which of the following?

Engine companies are typically responsible for connecting to standpipe systems in buildings to provide effective firefighting capabilities. The correct answer highlights essential equipment that is critical for this function.

Carrying hoses allows firefighters to effectively deliver water from the standpipe to the fire. Nozzles are vital as they control the flow and direction of water, allowing for targeted application on the fire. Spanner wrenches are used to tighten or loosen hose couplings, ensuring secure connections between hoses and the standpipe, which is crucial for maintaining an uninterrupted water supply during firefighting operations. Adapters are necessary to connect hoses to different types of fittings, which can vary based on the building's standpipe system.

The combination of these items ensures that a firefighting team is fully equipped to engage effectively with standpipe systems, facilitating rapid fire suppression efforts in high-rise or multi-story buildings.
