The main safety net in open work areas. Therefore, we must have a weather resistance. Weather resistant materials are nylon, polyvinyl alcohol and polyester. With a network of building materials used should be the same safety net manufacturers, their wet to dry strength ratio should be greater than 75% of the building fire safety nets, each net total weight does not exceed 15kg. Retardant safety net continued burning, smoldering time shall not exceed 4s. (4) flat screen width of not less than 3m, established networks and dense mesh safety net width of not less than 12m. Tether length not less than 0.8m. Safety net tether and tether spacing should not exceed 0.75m. Dense mesh safety net tether and tether spacing should not exceed 0.45m, the distance between the safety net tendons rope not too small, the general provisions of the above 0.3m. Safety nets can be divided into manual and mechanical knitting knitting. Can be divided into mechanical knotted and knotless knot knitting knitting. Generally, knotless knot strength higher than net have webs knot strength. Network node and section head must be fixed firmly, not moving, to avoid increasing the mesh side length and uneven. Such a situation would lead to stress is not concentrated, until net rope breaks. Before using the standard use of the safety net should be checked for corrosion and damage. Construction safety net to ensure complete and effective, reasonable support, even by force, not a debris inside the net.
