How to use fire hydrants

1. Open the fire hydrant door: 2. One person connects the gun head and hose to the fire point: 3. Another person connects the hose to the valve port: 4. Turn the fire hydrant handwheel counterclockwise to spray fire.

Note: When the electrical appliance is on fire, be sure to cut off the power supply. Put the hose in the direction of fire to avoid distortion.

Extended data:

Initial fire fighting skill: 1. Back to the exit. For your own safety, you should turn your back to the safety exit when putting out the fire. Once the initial fire fighting fails, you can quickly evacuate the fire. 2. Don't be confused by the rising flames and smoke when using a fire extinguisher to aim at the fire source. When spraying, aim the nozzle at the root of the flame and swing from far to near until it goes out.

3, downwind fire fighting, to stand in the windward, downwind fire fighting, prevent the wind blowing flame to ignite itself. 4. After the fire goes out, water it again, so as to completely put it out, in case of "resurgence".

How to use the fire hydrant?

How to use the fire hydrant: Step 1: Press the spring lock on the door, and the bolt will automatically exit and open the fire hydrant door.

Step 2: After opening the door, remove the water gun rotating hose tray and unfold the fire hose along it. Step 3: Connect the hose interface with the fire hydrant interface, and pull the power switch of the kilometer wall in the box.

Step 4: Unscrew the handwheel of indoor fire hydrant according to the opening direction, and open the valve to spray water. Introduction of fire hydrant: Fire hydrant, officially named as fire hydrant, is a fixed fire-fighting facility, whose main function is to control combustible substances, isolate combustion-supporting substances and eliminate ignition sources.

There are indoor hydrants and outdoor hydrants. Fire fighting systems include outdoor fire hydrant system, indoor fire hydrant system and fire extinguisher system, and some will also have automatic sprinkler system, water cannon system, gas fire extinguishing system, fire detection system and water mist system.

Fire hydrants are mainly used for fire engines to take water from municipal water supply network or outdoor fire water supply network to extinguish fire, and can also be directly connected with hoses and water guns to extinguish fire. Therefore, the indoor and outdoor fire hydrant system is also one of the important fire fighting facilities.

Precautions for using fire hydrants: 1. When the building is within the protection radius of municipal fire hydrant 150m, and the fire water consumption does not exceed 15L/s, outdoor fire hydrant is not required. 2. Outdoor fire hydrants should be evenly arranged around high-rise buildings and should not be concentrated on one side of the building.

3. The outdoor fire hydrant of the civil air defense project should not be less than 5 m from the entrance of the civil air defense project. 4. The outdoor fire hydrant of the parking lot should be set around the parking lot, and the distance from the nearest row of cars should not be less than 7m, and the distance from the gas station or garage should not be less than15 m..4

5. Outdoor fire hydrants should be set in places where it is convenient for fire engines to pass. 6. Outdoor fire hydrants should be on the ground. When using underground fire hydrants, there should be obvious signs.

The underground type is used in cold areas, and the ground type is used in non-cold areas. If conditions permit, the ground type can be used for collision avoidance. 7. The diameter of outdoor fire hydrant on the ground should be150mm or100mm, with two bolts with a diameter of 65mm. ..

The outdoor underground fire hydrant should have a spigot with diameters of 100 and 65mm respectively. 8. The protection radius of outdoor fire hydrants should not exceed 150m, and the spacing should not exceed 120m.

9. The outdoor fire hydrant is not more than 2m from the roadside and not less than 5m from the external wall of the house.

Fixed fire extinguishing tools. The main function is to control combustible materials, isolate combustion-supporting materials and eliminate ignition sources.

Fire fighting systems include outdoor fire hydrant system, indoor fire hydrant system and fire extinguisher system, and some will also have automatic sprinkler system, water cannon system, gas fire extinguishing system, fire detection system and water mist system. [Edit this paragraph] Fire hydrant location 1. Fire hydrants should be placed in public spaces such as corridors or halls, generally in the walls of the above spaces. No matter what decorations are made on it, eye-catching signs (marked "fire hydrant") are required, and obstacles are not allowed in front to avoid affecting the opening of fire hydrant doors.

2. Fire hydrants are separated in a room (such as a box), which does not meet the fire control requirements. It is also not conducive to the timely rescue of firefighters. [Edit this paragraph] How to use the fire hydrant 1? Open the fire hydrant door and press the internal fire alarm button (this button is used to alarm and start the fire pump).

2. One person connects the gun head and hose to the fire point.

3. A second person connects the hose to the valve port.

4. Open the valve counterclockwise and spray water. Note: Be sure to cut off the power supply to prevent electrical fire.

Location of fire hydrant

1. Fire hydrants should be placed in public spaces such as corridors or halls, generally in the walls of the above spaces. No matter what decoration is done on it, it is required to have an eye-catching label (marked "fire hydrant"), and no obstacles should be set in front to avoid affecting the opening of the fire hydrant door.

2. Fire hydrants are separated in a room (such as a box), which does not meet the requirements of fire control and is not conducive to timely rescue by firefighters.

How to use fire hydrants

1. Open the fire hydrant door and press the internal fire alarm button (this button is used to alarm and start the fire pump).

2. One person connects the gun head and hose to the fire point.

3. A second person connects the hose to the valve port.

4. Open the valve counterclockwise and spray water. Note: Be sure to cut off the power supply to prevent electrical fire.

What are the steps to use the fire hydrant?

For indoor use 1, open the fire hydrant door and press the internal water pump alarm button (this button is to start the fire pump and give an alarm).

2. One person connects the gun head and hose to the fire point. 3. Another person connects the other end of the hose to the aluminum port of the plug.

4. Open the valve counterclockwise and spray water. Note: Be sure to cut off the power supply to prevent electrical fire.

For outdoor use 1, open the water bag connection switch of the underground fire hydrant with a wrench. 2. Connect the fire hose.

3. Open the outlet valve switch of the underground fire hydrant with a wrench. 4. Connect the hose port and the nozzle head.

5, at least two people holding water gun head, spray water to the fire, until the fire goes out. Fire hydrant installation points: Fire hydrant: a device connected with fire water supply system or water supply system, with on-off valve and one or more water outlets for supplying water to fire hose or fire truck.

Fire hydrant is divided into indoor fire hydrant and outdoor fire hydrant. When indoor and outdoor fire hydrants are directly supplied by municipal water supply pipes and an independent fire water supply system is adopted, a backflow preventer should be set at the interface with the municipal water supply pipe network.

The water filling time of dry hydrant system should not exceed 3min. 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.

Outdoor fire hydrants should be evenly arranged around high-rise buildings and should not be concentrated on one side of the building. The number of outdoor fire hydrants on one side of high-rise buildings should not be less than two. Outdoor fire hydrants should be set in front of the backflow preventer of the household pipeline from the municipal water supply network.

The application valve of fire water supply network is divided into several independent sections, and the number of fire hydrants in each section should not exceed 5. The distance between outdoor fire hydrant and fire pump adapter should not be less than 15m, nor should it be greater than 40m.
