The correct use of fire hose

Fire hoses are hoses used to carry fire-retardant liquids such as high-pressure water or foam. The traditional fire hose is lined with rubber and the outer surface is covered with linen weaving. Advanced fire hoses are made of polymer materials such as polyurethane. Fire hoses have metal fittings on both ends. You can attach another hose to extend the distance or connect the nozzle to increase the liquid injection pressure.

1. Open the fire plug door and take out the hose and water gun.

2. Check whether the hoses and joints are in good condition and use them if they are damaged.

3. Lay the hose in the direction of the fire to avoid kinking.

4. Connect the hose near the fire hydrant and the fire hydrant. When connecting, insert the connecting buckle into the chute and tighten clockwise.

5. Connect the other end of the hose to the water gun (the connection procedure is the same as the fire hydrant connection).

6. After the connection is complete, at least 2 people hold the water gun and aim at the fire (not to the person, to prevent high pressure water injury).

7. Slowly open the fire hydrant valve to the maximum and fire at the root of the fire.

8. When the fire hose is connected, the fire hose must be covered with a layer of soft protection when it is put on the fire hose interface, and then it is fastened with galvanized iron wire or hose clamp.

9, the use of fire hose. When using fire-fighting fire hoses, fire-fighting hoses that are resistant to high pressure should be placed close to the water pump. Fire-fighting hoses that are filled with water should be prevented from torsion or sudden bending, and the fire hose interface should be protected from collision damage.

10. Fire hose laying. When laying fire hoses, avoid sharp objects and various types of oil. When laying fire hoses vertically, use fire hose hooks and put fire hoses through traffic lanes. When protecting the bridge and passing through the railway, the fire hose should be passed under the track to prevent the fire hose from being damaged due to wheel abrasion and intermittent water supply.

11. Prevent ice formation. During the severe winter season, when the supply of water needs to be suspended on the fire site, in order to prevent the fire hose from freezing, the water pump needs to run at a slow speed and maintain a relatively small amount of water.

12, fire hose cleaning, fire hose after use, to clean, the fire hose to transport foam, must be carefully scrub, protective adhesive layer. In order to remove the grease from the fire hose, it may be washed with warm water or soap. For the frozen fire hose, it must first be used for melting. Then, the fire hose that has been cleaned and dried and not dried should not be stored in roll. The maintenance of the quality of the fire hoses by the hoses directly affects the effectiveness of fire fighting. In the course of use, the maintenance must be strengthened.

1, management, fire hose must have someone responsible for management, to prevent unwarranted damage, all hose should be classified according to quality, numbering in order to grasp the use of water.

2, storage, fire hose can not be placed in the outdoor sun and rain for a long time, can not be placed near the heat source, to prevent aging, to avoid corrosion and viscous material contamination, storage location, should have appropriate temperature and good ventilation, water should be The single layer is rolled up, placed on a hose rack or reel several times per year and folded several times in exchange, and the vehicle belt should avoid mutual friction. If necessary, exchange and fold.
