Fire hydrant

A fire hydrant, also known as a fire plug or johnny pump, is a tool used for fighting fires. They are usually found easily on streets, stuck to the road. The first fire hydrant recorded was in Philadelphia.
A fire hydrant is the primary method of firefighting in a municipal area. It is basically an outlet with a valve that provides water to the fire pumps or fire jeeps engaged in firefighting. Laws for keeping operational fire hydrants at specific intervals and with free access in buildings, factories, urban and developed areas are an important component of fire control and safety.
