Fire hydrant is a device that provides a water supply for firefighters to use in extinguishing fires. It is typically a metal pipe with a valve and a connection point for a fire hose. Fire hydrants are usually located along streets and are connected to an underground water main. When a fire occurs, firefighters can open the valve on the hydrant to release a high-pressure water supply. The water can then be directed onto the fire to help control and extinguish it. Fire hydrants are an essential part of firefighting infrastructure in cities and towns.
