WARNING
An expanded work zone combined with an SRD attached at or near foot level will have a high risk of serious injury or death.
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.
