Device lanyards and anchor lanyards should be able to withstand any dynamic forces 2.7.8.2.1 that might be imposed upon them in times of emergency. Device lanyards and anchor lanyards made of rope should have a performance at least equal to that of a “single” dynamic mountaineering rope, e.g. one conforming to European Standard EN 892 or the equivalent standard by the International Mountaineering and Climbing Federation (UIAA). Both these standards require the rope to have energy absorbing properties. Knots to be used for the terminations should be chosen for their energy absorbing characteristics as well as their strength and should be tied only by competent persons. The energy absorption provided by the materials used in the construction of the lanyard is enhanced by the knots used to terminate them and knotted terminations are therefore recommended. An example of a knot that is particularly good at absorbing energy is the scaffold knot (often referred to as a barrel knot), see Figure 2.3, which is
