3.0 INSTALLATION AND ADJUSTMENT
3.1 PLANNING: Plan your fall protection system before starting your work. Account for all factors that may affect your
safety before, during, and after a fall. Consider all requirements and limitations defined in Section 1.
3.2 ANCHORAGE: Figure 8 illustrates Energy Absorbing Lanyard anchorage. Select an anchorage location with minimal free
fall and swing fall hazards (see Section 1). Select a rigid anchorage point capable of sustaining the static loads defined in
Section 1. Where anchoring overhead is not feasible, Lanyards may be secured to an anchorage point below the level of the
user's Dorsal D-Ring, but must not be anchored below the worker's feet.
3.3 HARNESS CONNECTION: Energy Absorbing Lanyard must be used with a Full Body Harness. Attachment Elements
for Fall Arrest are marked by capital letter "A". For Fall Arrest applications, connect the energy absorber end of
the Lanyard to the back Dorsal Attachment Element (D-Ring) on the harness (see Figure 8), or front Sternal
Attachment Element (D-ring) on the chest. Consult the instructions included with your harness for other fall protection
applications and recommended harness connections.
Some Lanyard models are equipped with a Choker Loop that chokes on to the harness D-Ring or Web Loop (see
Figure 9). To choke the lanyard on to the Harness D-Ring or Web Loop:
1. Insert the lanyard web loop through the web loop or D-Ring on the harness.
2. Insert the appropriate end of the lanyard through the lanyard web loop.
3. Pull the lanyard through the connecting web loop to secure.Lanyard
3.4 ANCHORAGE CONNECTION: Figure 8 illustrates connection of the Energy Absorbing Lanyard to various anchorage
options. The anchorage end of the Energy Absorbing Lanyard is configured with various Hook, Tie-Back, and Rope
Grab options for attaching to anchorage:
• Hook Connection: Figure 8A shows connection to rebar with the Lanyard's Rebar Hook. Figure 8B shows
connection to a Tie-Off Adapter choked around an I-Beam with the Lanyard's Snap Hook. See Section 2 for
details regarding connector compatibility and proper connection.
• Tie-Back Connection: Figure 8C shows tie-back around a piece of angle iron with a Tie-Back Lanyard. Secure
the Tie-Back Lanyard around the anchorage structure as illustrated in Figure 10:
1. Hang the leg of the Tie-Back Lanyard over the anchorage structure without twisting the Lanyard. Adjust
the Floating D-Ring (A) so it hangs below the anchorage structure. Secure the Lanyard Snap Hook on the
Floating D-Ring. Ensure the Lanyard is cinched tight around the anchorage structure.
2. Do not allow the Snap Hook Gate (B) to contact the anchorage structure.
• Rope Grab Connection: Figure 8D shows an Energy Absorbing Lanyard with a Rope Grab connected to a
Vertical Lifeline. See the instructions included with your Vertical Lifeline for details regarding installation and use
of the Rope Grab.
;
Self-Retracting Devices: Do not connect an Energy Absorbing Lanyard or Energy Absorber to a Self-
Retracting Device (SRD). Special applications exist where connection to an SRD may be permissible. Contact 3M
Fall Protection.
3.5 LANYARD ADJUSTMENT: Some Lanyard models are equipped with an Adjuster to shorten or lengthen the Lanyard
Leg(s) and eliminate Lanyard slack. Keeping the Lanyard taught reduces the chance of tripping on the lanyard or
snagging the lanyard on surrounding objects.
• Buckle Adjuster (Figure 11): To adjust the length of the Lanyard Leg:
1. Slide the Loop Keeper (A) away from the Buckle Adjuster (B).
2. Slide the Buckle Adjuster up or down the webbing to shorten or lengthen the Lanyard Leg.
3. Slide the Loop Keeper back to secure the webbing and Buckle Adjuster.
