Principles for the layout of indoor fire hydrants

The following principles are followed for arranging indoor fire hydrants:

1. Ensure that two water guns can reach any part of the room at the same time when a fire occurs

When setting up indoor fire hydrants, Fire hydrants should also be arranged according to different fire protection zones. When there are two or more fire protection zones on a floor, a fire door is provided between the fire protection zones. The fire door will be closed in the event of a fire. If the indoor fire hydrant does not have two water guns, the fire hydrant in the fire protection zone will be threatened by fire. Difficult to use normally.

The fire point may lose the best time to extinguish the fire due to lack of effective control, resulting in the fire becoming larger. Therefore, when designing indoor fire hydrants, except for some special circumstances such as civil air defense projects, it is basically necessary to ensure that every point in the building is protected by two fire hydrants.

2. Control the spacing of fire hydrants

The installation height of the indoor fire hydrant spout should be convenient for the connection and use of fire hoses. The height from the ground should be 1.1m, and the water outlet direction should be It is convenient for the laying of fire hoses and should be at 90° or downward to the wall where the fire hydrants are installed.

In buildings where fire hydrants are arranged according to 2 full water columns of 2 fire water guns, the distance between fire hydrants should not be greater than 30.0m. In buildings where fire hydrants are arranged according to one full water column of one fire water gun, the distance between fire hydrants should not be greater than 50.0m.

3. The layout should be carried out according to the requirements of fire protection zoning

Conceptually speaking, fire protection zoning refers to the use of fire-resistant partitions in order to control the fire situation and reduce fire losses. . It plays a certain role in preventing the spread of fire.

Therefore, fire partitions should not be artificially destroyed. Use indoor fire hydrants in non-fire fire partitions to extinguish fires in another adjacent fire partition by passing through the fire partitions. When arranging indoor fire hydrants, the spacing should be considered independently of fire zones.

4. Fire hydrants should be installed on every floor of a building for fire protection and water supply, except for floors without combustibles.

On every floor of a building for fire protection and water supply, except for floors without combustibles Fire hydrants must be installed outside the floors. For special buildings, if some buildings have a partial second floor or more, and there is a lack of fireproof isolation between the upper and lower floors, they belong to fireproof zones.

At this time, indoor fire hydrants should be installed on each floor. If the area of ??the local second floor is small and the water column of the fire hydrant on the lower floor can reach any part of the second floor indoors, then no fire hydrant should be installed on the local second floor. When setting up indoor fire hydrants, the convenience of access, operation and coordination should be fully taken into consideration, and the layout should be based on the actual situation. It should take into account both the broad area and the focus.

In short, as my country's urbanization process continues to accelerate, the number of various types of buildings has increased dramatically. At the same time, building fires have also continued to increase. Therefore, when we arrange fire hydrants indoors, we must strictly follow the regulations to protect ourselves and our families.
