Excerpt from the Australian Standard for Safety Nets. 1. Dimensions
1.1 A safety net must be approximately 5.5m in length and 2.5m in width, except where a surveyor permits the use of a smaller net, but in no case must a safety net measure less than 3.7m in length and 2.5m in width. 1.2 An aperture of the mesh of a safety net must be not more than 190mm measured between opposite knots when the mesh is hung or cut to make it square mesh. 2. Construction
2.1 A safety net is to consist of a framing rope and netting both resistant to actinic degredation and having at least 400kgwt and 125kgwt breaking strain respectively. 2.2 The safety net is to be secured in position at each corner, and intermediate points if required, by suitably secured lengths of framing rope. 2.3 The corners of each mesh of a safety net must be properly secured so as to prevent movement. |
