SRD Instruction Manual
Locking Speed:
Use extreme caution when working on low-pitched roofs where a worker may slide, rather than fall. A
clear path is require to ensure positive locking of the Self-Retracting Lifeline.
Fall Clearance:
Consider the following when calculating fall clearance. Clearance required is dependent on the following
factors:
x
Elevation of Anchorage
x
Connecting Subsystem Length
x
Deceleration Distance
x
Free Fall Distance
x
Worker Height
x
D-ring / connector length
x
Movement of Harness Attachment Element
x
Length of Full Body Harness (FBH) Stretch
x
Working Level
See Illustration 4.
If there is a risk of a fall or if the only anchorage
point is below the attachment points on the
harness, it is essential to use a lanyard
provided with an energy absorber. Before using
a shock absorbing lanyard, ensure that there is
sufficient fall clearance below the user to
prevent any collision with the structure or the
ground.
Calculating Total Fall Distances:
Total Fall Clearance below worker is calculated from Anchorage Connection. Free Fall Di
Working Level + Energy Ab Deceleration Di Worker Connector
Safety Factor. Ensure that the total fall distance is clear of obstructions and equipment. Avoid
potential contact with a lower level. See Illustration 5.
