(4) Tie-off of the rope lanyard or lifeline around an “H” or “I” beam or similar help can lessen its strength just as much as 70 % as a result of cutting action associated with beam sides. Consequently, usage should always be made from a webbing lanyard or wire core lifeline across the beam; or even the lanyard or lifeline must certanly be protected through the advantage; or fall that is free must be significantly minimized.
(5) Tie-off where in fact the line passes over or just around rough or razor-sharp areas decreases power drastically. This kind of tie-off should always be prevented or an alternative tie-off rigging should be properly used. Such alternatives can include usage of a ring that is snap-hook/dee, cable rope tie-off, a successful cushioning regarding the areas, or an abrasion-resistance band around or higher the situation surface.
