Fall Protection​


​​Under​standing Sharp and Leading Edges​
Sharp Edge: A sharp edge is one ​​that, for practical purposes, is not rounded and has the potential to cut most types of lifelines. The ANSI sta​ndard for sharp edges, for example, involves testing the fall arrest device's lifeline over a piece o​f steel bar with a radius of no more than 0.005" (5 one thousands of an inch). If the lifeline is cut or severely​​ damaged, the device fails the test and does not comply with ANSI. ​​ Leading Edge: To visualize a leading edge, imagine a worker installing steel decking on​ a new building. Now imagine the worker's fall protection system is anchored at foot level behind ​him.
As the worker moves out and away from the anchor point while installing th​e decking, the worker is exposed to a potential fall over the edge of the building. This can also be considered a leading edge and be a potential​ hazard. ​​​​​​​​​​​​​​​
