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 defi ned in Section Section 2.
3.2
ANCHORAGE: Figure 8 illustrates Energy Absorbing Lanyard anchorage. Select an anchorage location with minimal free fall
and swing fall hazards (see Section Section 2). Select a rigid anchorage point capable of sustaining the static loads defi ned in
Section 1. Where anchoring overhead is not feasible, EZ Stop 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. 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). 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 confi gured 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 11:
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.
•
WrapBax Connection: Figure 11 also shows tie-back around anchorage structure with a WrapBax Lanyard. WrapBax
Lanyards are equipped with special Snap Hooks that can connect around their own Lanyard Leg:
1.
Hang the leg of the WrapBax Lanyard over the anchorage structure without twisting the Lanyard. Wrap the
Lanyard Leg around the anchorage structure and fasten the Snap Hook around its own leg. The Lanyard Leg may
wrap around the structure multiple times, but the Snap Hook must only fasten around one wrap of the leg.
2.
Do not allow the Snap Hook Gate (B) to contact the anchorage structure.
•
Rope Grab Connection: Figure 8C 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 have 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 12): 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.
4.0 OPERATION
First time or infrequent users of Energy Absorbing Lanyards (Lanyards) should review the "Safety Information" at
the beginning of this manual prior to use of the Lanyard.
4.1
WORKER INSPECTION: Before each use, inspect the Energy Absorbing Lanyard per the inspection checklist in the Inspection
and Maintenance Log (Table 2). If inspection reveals an unsafe condition or indicates the Lanyard has been subjected to fall
forces, the Lanyard must be removed from service and destroyed.
4.2
AFTER A FALL: Any Lanyard which has been subjected to the forces of arresting a fall or exhibits damage consistent
with the effects of fall arrest forces as described in the Installation and Maintenance Log (Table 2) must be removed from
service immediately and destroyed.
