According to the protection radius of the fire hydrant and the water consumption of the outdoor fire hydrant, the discharge of each outdoor fire hydrant should be calculated according to 15L/s. The distance between the outdoor fire hydrant and the protected object should be in the range of 5-40m, which can be included in the number of outdoor fire hydrants.
Outdoor hydrants should be evenly arranged around high-rise buildings, and should not be centralized on one side of the building. The number of extinguishing hydrants on one side should not be less than 2.
