L.2.6.5.8 Guided type fall arresters can be used as back-up devices on the safety line during rope access activities. If guided type fall arresters are to be used as back-up devices, it is recommended that they have cams that engage automatically with the anchor line during a fall.L.2.6.6Retractable type fall arrestersL.2.6.6.1 Retractable type fall arresters are normally used in fall arrest systems without another back-up safety system. The retractable lanyard (a type of anchor line) retracts automatically back into its case when not under tension by the user, with the advantage that, in theory at least, any fall would be very short, i.e. just the distance taken for the brake to engage. Retractable type fall arresters can be used in rope access systems to provide back-up in place of or in addition to the safety line. When determining whether or not to use a retractable type fall arrester as part of a rope access system, the advice given in L.2.6.6.2 to L.2.6.6.6 should be considered.
