When there is a need to climb up, down, diagonally or horizontally on a structure such as E.2.3.1 a tower or mast, a method commonly employed is the use of twin-tailed (sometimes known as twin- legged) fall arrest lanyards. Twin-tailed fall arrest lanyards should employ a single energy dissipating feature, i.e. an energy absorber, to which at one end two lanyards are incorporated. These are the tails (or legs). The other end of the energy absorber is intended for attachment to a fall arrest harness. See Figure E.2 for an example of a twin-tailed energy-absorbing fall arrest lanyard. Each tail end is fitted with a suitable connector, which, in use, is connected to the structure alternately as progress is made, in such a way that the length of any potential fall is minimised. Should a fall occur, the load is taken by a single energy absorber, which should perform as intended and keep the impact load to an acceptable level.
