Extended data

The function of fire hydrant:

It is generally believed that as long as the fire truck arrives at the fire scene, it can immediately get out of the water to put out the fire. In fact, a considerable number of fire engines equipped by the fire brigade do not mention water, such as lifting fire engines, emergency rescue vehicles, fire lighthouses and so on. , and must be used with fire engines.

However, due to the limited carrying capacity of some fire engines, it is urgent to find water sources when putting out fires. At this time, the fire hydrant will play a huge water supply function.

However, in real life, due to the weak awareness of fire safety of some units and individuals, fire hydrants are damaged in various ways, or lack of "arms" or "legs", and some fire hydrants located beside main streets are occupied and buried by construction projects;

Some fire hydrants are surrounded by vehicles and stalls, and they can't be connected at all, and some even have water supply interrupted, which seriously threatens the smooth development of fire fighting work. In the event of a fire, these fire hydrants will not play their due role.

Fire hydrant is an important tool to ensure the fire brigade to extinguish fire. Its absence and damage pose a serious threat to people's lives and property. So I hope that while caring for public facilities in other cities, we should also pay attention to the "safety" of fire hydrants!
