L.2.6.7.3.3 Great care has to be taken not to over-tension the flexible horizontal anchor line during installation, as over-tensioning can result in unforeseen and possibly unacceptable high loads at the extremity anchors. In addition, particular attention needs to be paid to the potential loads that could be applied to the extremity anchors should they be called upon to arrest a fall, which can be much higher than might be expected. The applied loads in an incorrectly tensioned system can be catastrophic. The loads should be calculated by a competent person and steps taken to ensure that the system is safe, before it is used. See Part 2, Figure 2.4 for examples of multiplier effects caused by increase in angles.
