F.2.4.14 When the choice at a work site is to use only ground anchors, there should be a minimum of two ground anchors for each rope access system, see a and b in Figure F.6, to provide independent anchor points for the working line and the safety line.F.2.4.15 Tests have shown that an effective position for the second ground anchor (e.g. b in Figure F.6) is to install it approximately 300 mm away from and parallel to the first ground anchor (a in Figure F. 6) and with the second ground anchor elements set approximately 500 mm back from the first ground anchor elements, i.e. so they are offset, e.g. as shown in Figure F.6.F.2.4.16 The included angle created by the connecting lines emanating from each leading ground anchor element should be such that all the ground anchor elements of each ground anchor are loaded as equally as possible.Designs and configurations of ground anchors not covered by this annex should beF.2.4.17 tested extensively and proved to be reliable before being put into use.F.3
