When using a lined fire hose, first open the fire hydrant cabinet, remove the hose and nozzle, and inspect them for damage; do not use the equipment if any damage is found. Lay out the hose toward the fire, ensuring there are no kinks. Connect the hydrant-end of the hose to the fire hydrant by inserting the coupling lugs precisely into the slots and tightening clockwise, then connect the other end to the nozzle. Once connected, at least two people should firmly hold the nozzle and aim it at the fire (do not aim at people, as high-pressure water can cause injury); slowly open the hydrant valve fully and direct the water stream at the base of the fire to extinguish it.

During use, avoid sharp bends or twisting when laying out the hose, and do not drag it forcefully across the ground after it is filled with water. Prevent contact with corrosive substances such as oils, acids, or alkalis. Additionally, avoid laying the hose over sharp objects; use hose hooks when laying it vertically to a height, and use hose bridges when crossing traffic routes. When crossing railway tracks, pass the hose underneath the rails to prevent it from being crushed by train wheels, which would interrupt the water supply. In freezing winter conditions, if the water supply must be paused during firefighting operations, keep the pump running at low speed with a minimal flow rate to prevent the hose from freezing. If small holes or leaks are detected during use, wrap the area tightly with a hose repair bandage and arrange for professional repair (weaving or patching) as soon as possible; if significant damage occurs, immediately remove the hose from service.
