Abstract: A fall arrest anchor for minimizing risk of falls and multiple configurations appropriate to different specific construction situations is provided. The fall arrest anchor comprises a dual anchor having an open first end and an open second end with the open first end being opposite the open second end. An amount of cast concrete completely encases the dual anchor between the first end and the second end. An upper fall arrest attachment is releasably securable within the open first end of the dual anchor. A lower fall arrest attachment is releasably securable within the open second end of the dual anchor. The dual anchor allows for sequential placement on a perimeter of elevated surfaces either as tie-offs or for holding static perimeter lines, mitigating risks of work on leading edges in general and on high rise roof tops with low parapet walls.
