What is a life-line?








Life line is component that consists of a flexible line that connects to an anchorage at one end to hang vertically or that connects to anchorages at both ends to stretch horizontally and which serves

as a method to connect component of a personnel fall arrest system to the anchorage.
 



How can we calculate the safe anchorage of a life-line? 




When life is used they shall be fastened to fixed safe points of anchorage capable of supporting 2300 kilos shall be independent, and shall be protected from sharp edges and abrasion. Safe anchorage points may include structural members (minimum 4 inches structural member or 4inces pipes) but do not include guard rails, vents, other small dia piping system, electrical conduit, outrigger beams or counter weights. It shall be made from 10mm dia wire ropes. Horizontal lifelines shall be installed at the highest feasible point, preferable above shoulder height. This life lines shall be maintained with unloaded sag at the centre no longer than 30cm (12inches) for every 10meters of life line length between attachment points.
