What are appurtenances in the context of NFPA 24?

Appurtenances in the context of NFPA 24 refer to components that are associated with fire service mains, which includes valves, fittings, and other necessary accessories that support the functionality and operation of the fire protection system. These components play a crucial role in managing water flow, maintaining pressure, and ensuring that the system can operate effectively during a fire emergency.

The inclusion of valves allows for the control of water supply to various parts of the fire service system, while fittings connect different sections of piping and ensure that the system remains watertight and operates efficiently. By understanding the significance of these appurtenances, one can appreciate how they contribute to the overall integrity and reliability of fire protection systems as defined in NFPA 24.
