<p>A safety harness has an eyelet (13) which is threaded with a safety line (10) fixed at both its ends with a safety hook (11,12) which is sized so as not to be able to pass through the eyelet (13). In normal use one hook (11,12) is attached to a life-line, or a load-transfer device engaged therewith. When two persons attached to the lifeline wish to pass, the other hook (12,11) can be clipped onto the life-line beyond the attachment at the time being of the person to be passed followed by subsequent release of the first hook (11,12). Such an arrangement obviates the need for two lanyards to accomplish such a passing manoeuvre. A resilient housing (14) may be located on the eyelet (13) for stowing the hook (11,12) not in use at any particular time.</p> |
