Are there any rules for the distance between fire hydrants and fire hoses?
According to regulations, fire hydrant water outlet from the ground should be 1.1 meters, fire hydrants are installed in the box with fire tubes, then the installation height of about 1 meters
In principle, the fire box should be placed in the fire hydrant near, the best is 10 meters, because the best time of fire fighting is 3 to 5 minutes, until the fire spread, fire extinguishing effect is obvious, the fire box is provided to facilitate water intake, but also the sun and rain prevention function.
In order to ensure that fire engines draw water from fire hydrants, fire hydrants should not be more than 2m from the roadside. In order to ensure the safety of fire hydrant, the outer wall should be less than 5m. The outdoor fire hydrant is used for fire engines, therefore, the protective radius of the fire engine is the protective radius of the fire hydrant, and the maximum water supply distance (i.e. the radius of protection) of the fire engine is 150m, so the protective radius of the fire hydrant is 150m.
