Safeguard Horizontal Lifelines

These are linear anchoring devices used in Fall Arrest and Fall Protection Systems, which allow workers to move along the whole length of the Fall Protection System, usually without needing to disconnect and fixing points of the anchorage.

It is normally essential to include energy (or shock) absorbers within HLL in your Fall Arrest System in addition to those within the workers’ PPE. Without such absorbers, the horizontal lifeline cannot deform significantly when arresting the fall. Because of the geometry of pulling across the horizontal lifeline, this in turn results in large resolved forces being generated within the anchor system, sufficient to cause failure of the anchorage. This can occur even with energy absorbers being included in the PPE of the worker.

The load and horizontal line geometry in horizontal lifelines usually creates falls in excess of the 6 ft limit of the standard, limiting HLL design to standard-defined “qualified persons”. (The recognition of these basic weaknesses have resulted in most temporary “wrapped structure” HLL anchors, which were anchors made from a wire rope wrapped around a structure and its ends fastened together by wire rope clips, being replaced by fixed-point anchors or HLL systems designed by defined “qualified” persons.)
