If referring to SNI (Indonesian National Standard) and NFPA (National Fire Protection Association), the placement of Hydrant Pillar is determined based on the following:
The location and amount of hydrant (hydrant box and hydrant pillar) output are needed to determine the capacity of the pump as a medium for attracting and spraying water from reservoirs.
A good Hydrant placement distance is 35-38 meters between one another. because, the fire hose has a hydrant box whose length is 30 meters, while the water spray can reach 5 meters from the fire hose nozzle.
In buildings or buildings that are more than 8 stories high, hydrants must also be provided to prevent fires from spreading to adjacent buildings.
Hydrant Pillar and Hydrant Box are placed in a place that is easily accessible and safe, usually placed near the emergency exit.
