IV. Use Warnings, Restrictions and Cautions
a. Adequate Anchorages
FALL CLEARANCE: Ensure sufficient clearance exists in your
fall path to prevent striking an
object during a fall. The clearance
required is dependent upon
the subsystem (rope grab and
lanyard, rope grab and carabiner)
and lifeline properties. The chart
to the right shows the approximate
elongation for new Werner Co.
lifelines in dry conditions. The
elongation speciied is for an
applied static load of 1,800 lbs
(8 kN). Wet ropes generally have
more elongation than dry ropes.
Allow for additional elongation in
wet or humid conditions. Lifeline
elongation must be considered
when estimating fall clearance.
SHARP EDGES: Avoid working
where your lifeline, lifeline subsystem, or other system components
will be in contact with, or abrade against, unprotected sharp edges.
Do not loop a lifeline around small diameter structural members. If
