F.2.2.7 Normally, only one rope access technician should be attached to any one span of the anchor rail at any one time. When establishing the static strength of an anchor rail, the possibility of use by more than one person per span should be taken into consideration and the strength increased accordingly. Advice on what the increase should be is not given in this annex because opinions vary between different countries, their authorities and their standards bodies. Consideration should also be given to extra loads that may be imposed during rescue.Figure F.3 — Example of an anchor rail© IRATA InternationalAnnex F: Page 6 of 212013-Sep-01IRATA International code of practice for industrial rope access Part 3 of 5: Informative annexes: Annex FF.2.3 Paired anchor devices
