of a PFAS. Some considerations are listed below (see APPLICATIONS,
item B. USE LIMITATIONS section for additional details);
1) Anchorage Selection. In addition to strength considerations, the
anchorage should be rigged to prevent a fall onto the structure when
considering 2) and 4) below.
2) Swing pendulum fall
3) Rough surfaces or unprotected sharp edges that could cut or abrade
the equipment if unprotected.
4) Workplace geometry
a) Free fall distance - Personal fall arrest systems used with this
equipment should be mounted overhead in such a way as to
eliminate the possibility of a free fall. For units 4004 & 4005, the
free fall must be limited to 4' (1.2m) or less.
b) Deceleration distance - Maximum 30 in (.76m)
c) Total fall distance - The sum of the activation distance and
deceleration distance plus a safety margin.
d) A careful examination must be made of the workplace by a Com-
petent Person before the selection or installation of Skyloc™ an-
chorage points. Consideration must be given both to the move-
ment of materials (Will cranes be used to "fly" equipment or parts
in?) and workers around the workplace to ensure that potentially
hazardous situations are avoided.
e) Areas where overhead cranes or gantries are used must be ex-
amined to verify that neither the moving loads or lifting wires can
interfere or snag the extended wire rope / web of a Skyloc™ SRL
causing a worker to be dislodged.
f) Overhead lighting and electrical cables must also be identified to
insure that installation of the SRL is sufficiently far enough away
so that the cable can never contact the wire creating an electrocu-
tion hazard.
g) Consideration of obstacles present in the work area must include
ALL locations that COULD be reached if the entire length of wire
rope / web were extracted from the SRL. Obstacles that pose no
threat when a worker is on a platform, for example, may be ex-
posed to a dangerous situation should he climb downwards or
moves laterally towards another work surface.
h) The wire rope / web used in SRL's should be protected from dam-
age when passing over sharp edges or near objects where the
cable / web could become lodged or pinched through the use of
edge protectors that are not abrasive to the lifeline. When sig-
nificant changes in angle are encountered, directional sheaves
