Fire hose connection. When the fire hose is put on the fire hose connector, it must be covered with a layer of soft protection, and then fastened with galvanized iron wire or hose clamp.

Application of fire hose. When applying fire hoses, the high-pressure fire hoses should be connected close to the water pump. The fire hoses should not be twisted or bent abruptly after being filled with water. In addition, the fire hose joints should be prevented from being damaged by impact. Fire hose paving. When paving fire hoses, avoid sharp objects and various oils. When paving fire hoses vertically to a high place, use fire hose hooks. When paving fire hoses with the help of traffic arteries, pave fire hoses. When using the railway to protect the bridge, the fire hose needs to be drawn from under the track to prevent the fire hose from being crushed by tires and interrupting the water supply.

Maintenance method: avoid freezing. In the cold winter, when the water supply needs to be suspended on the fire site, in order to avoid freezing of the fire hose, the water pump needs to run at a low speed to maintain a small water output. The fire hose is clean. After the fire hose is applied, it must be clean and tidy. The fire hose that transports foam must be carefully cleaned to protect the glue layer. In order to better eliminate the oil stains on the hose, it can be cleaned with warm water or soap powder. For the frozen fire hose, first apply it to melt, and then clean and dry the fire hose that has not been dried. Volume storage.

Precautions for the use of fire hoses:
(1) Sudden twists and turns should be avoided during laying to prevent the ability to withstand water pressure from being reduced; twisting should also be avoided to prevent the hose from turning after being filled with water and disengaging the internal buckle hose connector.
(2) After filling with water, avoid dragging forcibly on the ground. When you need to change the position, try to lift and move as much as possible to reduce the wear of the hose and the ground.
(3) Avoid contact with corrosive chemicals such as oils, acids and alkalis.
(4) In areas where there may be flames or strong radiant heat, cotton or linen hose should be used.
(5) It should be cleaned after use, and the unlined hose should be hung in the sun. After drying, the coil should be stored in a cool and dry place.
(6) If any small holes are found to be damaged during use, they should be wrapped tightly with a hose cloth, and darn or glued as soon as possible afterwards; when there is obvious damage, they should immediately withdraw from combat readiness.
(7) When the vehicle needs to pass the laying hose, a hose bridge should be installed at the passing position in advance.
(8) If you pass the railway when laying, the hose should pass under the rail.
(9) After the hose and the interface are re-bound, the hose and the interface need to withstand 1.5 times the working pressure, and there should be no slippage, leakage, damage, etc.
