8. LABELS
All labels must be present and legible.
9. SRD in Non-LE Standard Mode:
The Leading Edge SRD may be used may be used as a standard SRD in an overhead condition, in which the SRD is
installed anywhere in the allowable attachment area, which ranges from directly above the user to level with the FBH D-ring, as shown in Figure
9A. The overhead condition MRFC has six metrics, labeled A – F, measured from the walking/working surface.
A = SRD deceleration distance
B = D-ring shift and harness stretch
C = Safety factor
D = Sub Total- Minimum Required Fall Clearance
E = *Additional Fall Clearance Calculation Due To Swing Fall.
F = Total Required Fall Clearance
The MRFC for an overhead anchorage, with no swing fall condition, is calculated as A+B+C=D.
The user must be aware that if a swing fall hazard exists, as shown in Figure 9B, additional steps are required. Use Chart 9 to determine the
amount of swing fall, and place that value in E. Add the E value to the D value to determine the total MRFC.
