The use of anchor points is an essential component of any fall protection system. The most common location for anchor points is on the roof, although they can also be installed on the walls, doors, and windows. Roof anchor points are the points at which lanyards, lifelines, and other types of tie-offs that protect workers from falling are connected to one another. Roof anchors can be as straightforward as a D-ring connection or as involved as an entire lifeline system. Either way, they come in a variety of degrees of complexity. There is the option of using either permanent or temporary anchor points.
