The free fall distance must be
determined and added to the value
from the table The free fall distance
can be determined by using the for-
mula:
FF = L + D – H
FF = Free Fall
L = the length of the lanyard.
D = the height of the worker’s D-ring
from the walking-working surface. This
can normally be assumed to be 5 ft.
H = Height of the HLL from the
walking-working surface. Please note
that the height of the HLL is not neces-
sarily the height of the anchorage.
Consider the sag of the cable.
For example, a 121-ft. span of
SWHR is 7 ft. above the walking-working
surface, and 2 workers will be using the
lifeline with 6-ft. shock absorbing lanyards.
Calculating the free fall: The free fall is calculated
by using the equation.
(6 ft (lanyard). + 5 ft.( D-ring height) – 7 ft (above the
walking working surface) = 4 ft. free fall)
