criteria, and ensure changes have not been made to
the system installation (i.e. length) or occurred at the
job site that could affect the required fall clearance.
Do not use the system if changes are required.
SYSTEM INSTALLATION:
Figure 1 shows a typical
Web horizontal lifeline installation. When using an
energy absorbing lanyard to connect to the system,
the end anchorages must be located at a height
which will limit the free fall to 6 feet (1.8m). When
using a self retracting lifeline (SRL) to connect to the
system, the end anchorages must be located above
the user. The SRL, when fully retracted, must be
above the harness attachment level. The horizontal
lifeline system should be positioned at a level that
will minimize free fall while allowing ease of use.
The horizontal lifeline should be positioned near
the work location to minimize swing fall hazards.
The connecting subsystem length should be kept as
short as possible to reduce the potential free fall and
required clearance distance. Both anchorages must
be installed at approximately the same elevation, so
that the horizontal lifeline system is not sloped more
than 5°.
Determine the locations of the end anchorages and
evaluate their strengths. Determine the span length
and evaluate the required clearance using Figures 5,
6, or 7 and Tables 1, 2 or 3.

Installing Tie-off Adapter to Vertical or Sloped
Anchorage Structure
Install the anchorage connectors. The Web Horizontal
Lifeline System includes two tie-off adaptor anchorage
connectors. To ensure the tie-off adaptor does not
slide down a vertical or sloped anchorage, the tie-off
adaptor must be wrapped twice around the structure
as shown in Figure 3. Refer to the tie-off adaptor
instructions for complete installation information.
The horizontal lifeline may be secured directly to
the anchorage when the anchorage incorporates
a compatible attachment element that meets the
requirements.
Secure each end of the horizontal lifeline to the
anchorage connectors with the snap hook or carabiner.
Installation Tip:
When attaching to the tie-off adaptor,
connect carrying bag through handle to secure bag
to the end of the system. Note: Bag handle is not to
be used as an anchorage connector, only to be held in
place by passing the connection through the handle.
Remove the slack from the horizontal lifeline by
pulling the web through the ratchet tensioner by
hand. Once the line is pulled through the adjuster
as tight as possible by hand, activate the ratchet by
rotating the handle back and forth in a 180 degree arc
to tension the webbing line tight.
PLEASE NOTE:
There is no in-line tension
indicator and it is recommended that the operator
tension the ratchet with one hand only on the
handle, and with no external parts be used to
further tighten the line. Normal working tension is
achieved by a one-handed operation will tension
the webbing line satisfactorily.
Installation Tip:
When wound onto the central
hub during tensioning, the webbing should have a
minimum of 1.5 times the revolution of the ratchet
hub. Should the webbing over
fi
ll the ratchet, it can
jam requiring the operator to release the line and
start again.
Once tensioned, the ratchet handle must be pushed
to the closed and locked position. Surplus webbing
should be folded and placed in the bag if attached or
near the end of the system away from center work
area.
PERSONAL FALL ARREST SYSTEM COMPONENTS:
Inspect and don the full body harness according to
manufacturer’s instructions. Attach the connecting
subsystem (energy absorbing lanyard or SRL) to the
dorsal connection on the harness.
