FHS-Fire Dry barrel Hydrant system
A Fire Hydrant System (FHS) is a critical fire safety infrastructure used to supply water for fighting fires in emergencies. It consists of a network of underground pipes, hydrants, pumps, and water tanks that are strategically placed throughout buildings, factories, and outdoor spaces. The system is designed to provide a reliable and easily accessible water source to fire service personnel, enabling them to control and extinguish fires quickly. Fire hydrants are usually located in accessible areas and are equipped with outlets for connecting hoses, allowing firefighters to directly tap into the water supply during a fire. The fire hydrant system is also equipped with pumps that ensure water pressure remains high enough for effective firefighting. It is an essential part of both industrial and residential fire protection systems, providing an immediate water source in the event of a fire, preventing significant property damage and safeguarding lives.
