What are devices called that facilitate water flow alongside fire hoses?

Appliances are devices used in fire service operations that help manage the flow of water through hoses and enhance the effectiveness of firefighting efforts. They encompass a range of equipment such as hose fittings, nozzles, adapters, and appliances for managing water flow, like pumps and manifolds. These devices are critical for controlling pressure, directing water, and connecting different lengths and types of hoses during firefighting operations.

In this context, appliances serve to facilitate the efficient transfer and distribution of water, allowing firefighters to effectively combat fires. Understanding the role of appliances is essential for proper implementation during firefighting scenarios, ensuring that water can be directed wherever it is needed most. This function differentiates them from other options, which do not specifically encompass the broader range of devices associated with managing water flow alongside hoses.
