E.2.3.4 It is essential that the design of a twin-tailed energy-absorbing fall arrest lanyard is such that no matter which direction the load in a fall is applied to the point where the lanyard tails are attached to the energy absorber, there is no catastrophic failure of any part of the twin-tailed fall arrest lanyard. Before using twin-tailed energy-absorbing fall arrest lanyards, rope access technicians are strongly advised to check the configurations permitted by the manufacturer. Conformance to an appropriate standard is recommended. An example of an appropriate standard for twin-tailed energy- absorbing fall arrest lanyards is British Standard BS 8513:2009, Personal fall protection equipment – Twin-legged energy-absorbing lanyards – Specification.
