The Protective net is one of the most effective safety protection facilities against falling accidents from heights. It also plays an important role in avoiding and mitigating falling and object damage injuries. The Protective Net is an essential protective equipment for working at height. Due to the different safety requirements of different construction projects, different specifications, and different erection methods. The safety protective net is mostly made of nylon rope with a diameter of 9 mm (also used with silk rope). Its mesh is 10~14cm, mesh 3m×6m and 4m×8m and other specifications, and the bearing requirement is not less than 160kg/m2. Since the safety Protective net is to protect the personal safety of workers at height and prevent falling objects from injuring people, the relevant regulations must be strictly observed during use.

1. Safety nets must be hung under the working parts at height; When the height of the building exceeds 4m, a safety protective net must be set up that gradually rises with the wall, and a fixed safety net must be set up every 4m; Safety protective nets must be set up on the outer frame, bridge frame, upper and lower opposite holes.

2. The erection of the security Protective net should be low inside and out, and the height difference of the expenditure part is generally about 5Ocm; No fracture or bending of the support members; The gap between the inner edge of the net and the wall should be less than 15cm; The distance between the lowest point of the net and the surface of the object below should be greater than 3m.

3. Check whether the safety net is corroded and damaged before use.

4. During construction, it is necessary to ensure that the safety net is complete and effective, reasonably supported, evenly stressed, and there must be no debris in the net. The lap joint should be tight and reliable, there should be no gaps, and the safety protective net erected must not be dismantled or damaged during construction, and it must be removed when there is no high place.

　　5. The diameter of the small head of the wooden pole shall not be less than 7cm, the diameter of the small head of the bamboo pole shall not be less than 8cm, and the spacing of the pole shall not be greater than 4m

6. When the erected safety protective net needs to be temporarily dismantled due to construction, the construction unit must notify and seek the consent of the erector before demolishing. After the completion of construction, it must be immediately restored by the construction unit in accordance with the requirements of the regulations, and can only be used after the erection unit has passed the inspection.

7. Clean up the debris in the net frequently; When carrying out welding operations above the net, effective measures should be taken to prevent welding sparks from falling on the net; Do not have severe acid and alkali fumes around the net for a long time.

8. The safety protective net must be checked frequently when used, and there are tracking records, and the safety net that does not meet the requirements should be dealt with in time.

9. The vertical network and the flat network must be strictly separated, and the vertical network is never allowed to be used as a flat network; When setting up a net, the tether on the bottom edge must be firmly tied.

10. When not in use, the safe protective net must be properly stored and kept to prevent moisture and mold.

11. Before using the new network, you must check the nameplate of the product: (1) whether it is a flat net or a vertical network; (2) Production license of the manufacturer; (3) The factory certificate of the product. The old network should be tested before use, and there is a test report, and the old network that passes the test can be used. The dynamic load test of the safety protective net is qualified with two pieces of 12Okg weight, 1.5m apart, and free landing impact from a height of 4-5m, and the safety protective net is intact.
