Energy-absorbing fall arrest lanyards should not be extended beyond the maximum E.2.2.6 length specified by the manufacturer, e.g. by linking two energy-absorbing fall arrest lanyards or other lanyards end to end. This is because the potential free fall distance is increased, with an increased risk of hitting the ground, structure or natural feature and, in addition, the loads on the user in a fall could rise to an unacceptable level.E.2.2.7 Two (or more) energy-absorbing fall arrest lanyards should not be used in parallel, i.e. side by side. This is because in a fall the load might be shared by both (or all) the energy absorbers. This is likely to cause them not to function as intended and for there to be an increase in the loads experienced, which could result in a serious injury. Also see E.2.3.2.
