1、建筑物内室外消火栓的布置，除应符合本节的规定外，还应符合市政消火栓一章的有关规定。
1. In addition to the provisions of this section, the layout of outdoor fire hydrants in buildings shall also comply with the relevant provisions of the chapter on municipal fire hydrants.
2、建筑物内室外消火栓的数量应根据室外消火栓的设计流量和保护半径计算确定。保护半径不应大于150m。每个室外消火栓的出水量应按10~15L/s计算，室外消火栓应均匀分布在建筑物周围。建筑物消防面一侧的室外消火栓数量不应少于2个。
2. The number of outdoor fire hydrants in the building shall be determined according to the design flow and protection radius of outdoor fire hydrants. The protection radius shall not be greater than 150m. The water output of each outdoor fire hydrant shall be calculated as 10~15l/s, and the outdoor fire hydrant shall be evenly distributed around the building. The number of outdoor fire hydrants on one side of the fire-fighting surface of the building shall not be less than 2.
3、人防工程、地下工程等建筑物的出入口附近应设置室外消火栓，出入口距离不小于5m。不应大于40m；小于7m，距离加油站或油库不小于15m。
3. Outdoor fire hydrants shall be set near the entrances and exits of civil air defense works, underground works and other buildings, and the distance between the entrances and exits shall not be less than 5m.

5、工艺单元区域内使用高压或临时高压消防供水系统的场所，应在其周围设置室外消火栓。数量应按设计流量计算确定，间距不大于60.0m。当工艺安装区宽度大于120m时，室外消火栓应安装在安装区的路边。
5. Outdoor fire hydrants shall be set around the places where high-pressure or temporary high-pressure fire water supply system is used in the process unit area. The quantity shall be calculated and determined according to the design flow, and the spacing shall not be greater than 60.0m. When the width of the process installation area is greater than 120m, the outdoor fire hydrant should be installed on the roadside of the installation area.
6、室外消防进水管装有防倒流器，发生火灾时室外消火栓因水头损失不能满足规范要求时，应安装室外消火栓在回流防止器前面。
6. The outdoor fire water inlet pipe is equipped with a backflow preventer. In case of a fire, the outdoor fire hydrant should be installed in front of the backflow preventer if it cannot meet the specification requirements due to the head loss.
