The fire hose is a hose used for water delivery at the fire scene. According to the material, it can be divided into lined fire hose and unlined fire hose. Among them, the unlined fire hose has low pressure resistance, high resistance, easy to leak, and is prone to mildew and rot, and has a short service life. Durable, not easy to leak, low resistance, can also be bent and folded at will, moved at will, easy to use, suitable for laying on external fire sites and connecting fire engines.
When using the fire hose, pay attention to:
1. When laying, sudden twists and turns should be avoided to prevent the ability to withstand water pressure; twisting should also be avoided to prevent the inner buckle hose connector from being disengaged due to the rotation of the hose after filling with water.
2. After filling with water, forceful dragging on the ground should be avoided. When the position needs to be changed, it should be lifted and moved as much as possible to reduce the abrasion between the hose and the ground.
3. Avoid contact with corrosive chemicals such as oil, acid, and alkali.
4. Cotton or hemp hose should be used in areas where flames or intense radiant heat are likely.
5. After use, it should be cleaned, and the unlined hose should be hung to dry, and the coil should be stored in a cool and dry place after drying.
6. If a damaged hole is found during use, it should be wrapped tightly with water tape, and darned or glued as soon as possible afterwards; when there is obvious damage, it should be withdrawn from combat readiness immediately.
7. When the vehicle needs to pass through the water belt under laying, the water belt protection bridge should be placed in the passing part in advance.
8. If it is necessary to pass the railway during laying, it should pass under the rail.
9. Lined hose should be used on the outside of buildings in cold regions to prevent the hose from freezing.
