What is the primary role of fire hydrants according to NFPA 24?

The primary role of fire hydrants, as outlined in NFPA 24, is to provide a source of water for firefighting operations. They are critical components of fire protection systems, allowing firefighters quick and easy access to a reliable water supply during emergencies. Fire hydrants are strategically placed within communities to ensure that response teams can efficiently tackle fires, ensuring that the fire can be suppressed effectively and safely.

While there are other uses for water sources, such as irrigation and providing drinking water in certain settings, those functions are not the primary focus of hydrants as per NFPA 24. Additionally, measuring water pressure is a function related to water systems but does not align with the main purpose of hydrants in fire service life safety and property protection. Hence, the emphasis on firefighting operations distinguishes the correct answer.
