1. A safety net must be hung below the working site at a high place; when the building height exceeds 4m, a safety net that gradually rises with the wall must be installed, and a fixed safety net will be installed every 4m in the future; on the outer frame and bridge type frame , Safety nets must be set at the upper and lower opposite holes. The safety net should be built inside low and high outside, and the height difference of the expenditure part is generally about 50cm; there is no fracture or bending of the supporting rods; the gap between the inner edge of the net and the wall must be less than 15cm; . The diameter of the small head of the wooden pole shall not be less than 7cm for the support used for the safety net erection, the diameter of the small head of the bamboo pole shall not be less than 8cm, and the distance between the braces shall not be greater than 4m.
2. Before use, check the safety net for corrosion and damage. During construction, it is necessary to ensure that the safety net is complete and effective, with reasonable support, uniform force, and no debris in the net. The overlap should be tight and secure, and there must be no gaps. The safety net erected must not be dismantled or damaged during construction, and it can only be removed when there is no high altitude operation. When the safety net that has been erected is temporarily dismantled due to the construction, the construction unit must notify and seek the consent of the erection unit before dismantling. The construction unit must be resumed by the construction unit immediately according to the regulations, and it can be used only after it has passed the inspection by the erection unit.
3. The debris in the net should be cleaned frequently. When performing welding operations above the net, effective measures should be taken to prevent welding sparks from falling on the net; there should be no severe acid and alkali fumes around the net for a long time.
