Under what circumstances can municipal fire hydrants be incorporated into indoor fire hydrants?
The number of outdoor fire hydrants should be determined by comprehensive calculation according to the protection radius of fire hydrants and the fire water consumption of outdoor fire hydrants. The water output of each outdoor hydrant is calculated as 15L/s, and municipal hydrants with a distance of 5 ~ 40m from the protected object can be included in the number of outdoor hydrants.
Article 28 of the Fire Protection Law stipulates that no unit or individual may damage, misappropriate or dismantle or stop fire control facilities and equipment without authorization, bury, occupy or block fire hydrants or occupy fire prevention spaces, or occupy, block or close evacuation passages, fire exits and fire truck passages.
Among them, "fire hydrant" refers to the fire water supply device connected to the water supply pipe network, which is composed of valves, water outlets and shells and is an important water supply device to prevent the spread and expansion of fire.

Article 7.3.6 of the High Code stipulates: "The number of outdoor fire hydrants shall be calculated and determined according to the water consumption of outdoor fire hydrants specified in Article 7.2.2 of the High Code, and the water consumption of each fire hydrant is10l/s ~15l/s."
In order to facilitate the use of fire engines, fire hydrants should be evenly arranged along the fire lane. If it can be arranged near the roadside of high-rise civil buildings, it can avoid the disadvantages of hose bursting caused by fire engines crushing hoses during fire fighting.
In order to facilitate the fire truck to take water directly from the fire hydrant, the distance between the fire hydrant and the roadside should not be more than 2 m; ; There should be a fireman's working site around the fire hydrant, so the distance from the external wall of the building should not be less than 5 m. At the same time, for the convenience of use, the distance between the fire hydrant and the protected building should not exceed 40 m.
