Examples not intended to depict the full extent of all hazardous sharp
edges found on jobsites for the user to identify and avoid.
5.3 Angle of Redirection:
The angle of redirection is the angle of the lifeline over an edge during a fall event. Install the SRD so that the
angle of the two parts of the lifeline are at least 90°, or more, but never less, as shown in Figure 10. The lifeline must never rise up to
the edge as it may bend the lifeline in too small a radius and/or severely abrade, or otherwise compromise, the lifeline.
Do not
work with the leading edge above the anchorage.
5.4 Edge Conditions:
Leading Edge conditions vary, and may be composed of steel, I-beams with purlins, steel deck, metal roofing, or
poured concrete or cinder block as shown in Figure 11.
