An expanded work zone combined with an SRD attached at or near foot level will have a high
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 5. 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.
