3.0 Installation
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 2.
3.2 ANCHORAGE: Figures 11 illustrates typical SRD anchorage connections. 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 defi ned in Section 1.
Where anchoring overhead is not feasible, Nano-Lok SRDs may be secured to an anchorage point below the level of the user's
Dorsal D-Ring. For users up to 140 kg (310 lbs), the anchorage point must not be more than 1.5 m (5 ft) below the Dorsal
D-Ring.
3.3 HARNESS MOUNTING: Nano-Lok Edge SRDs include an interface for mounting on a Full Body Harness just below the
Dorsal D-ring. The worker can then connect the lifeline end of the SRD to anchorage points located thoughout the work
site. To mount the Nano-Lok Edge SRD on a Full Body Harness (see Figure 10):
Some Full Body Harnesses are equipped with a Personal SRD Link (PSRD Link) that integrates the Dorsal
D-Ring with attachment elements for Harness Mounted Self-Retracting Devices (Figure 9).
1. Loosen the Harness Webbing: Pull out on both Shoulder Straps (A) where they pass through the bottom of the
Dorsal D-Ring (B) until there is suffi cient space to slide the locking pin between the Shoulder Straps and Back Pad.
2. Open the Harness Interface: Push down on the Locking Buttons (C) simultaneously and slide the Locking Pin (D)
out.
3. Insert the Locking Pin Through the Shoulder Straps: With the Locking Buttons (C) facing out and Locking Pin
facing up, insert the Detent Pin (D) of the Harness Interface (E) behind both Shoulder Straps (A) and lock in place.
Pull the shoulder Straps back through the Dorsal D-Ring and Back Pad to remove slack.
4. Connect Hook and Loop Straps around the Shoulder Straps: Open the hook and loop straps (F) located on the
bottom of the Energy Absorber Pack. Wrap the hook and loop straps around the Shoulder Straps and secure.
The Red Band on the knob end of the Harness Interface Locking Pin will be exposed if the Harness
Interface is unlocked. To avoid accidental release of the connection, always make sure the Harness Interface
is locked before using the Harness and attached SRD. Failure to do so could result in injury or death.
5. Alternate Attachment Strap: The Nano-Lok Edge SRD Attachment Strap (3100184), can be used as an alternative
means of securing the bottom of the Nano-Lok Edge Pack when the harness geometry precludes the use of the
integral hook and loop straps. (See fi gure 20) and refer to Placement Instructions below.
A. Placement Instructions: Figure 20A, shows the Nano-Lok Edge SRD Attachment Strap.
1. Note that the Nano-Lok Edge SRD Attachment Strap uses hook and loop closures: Hook ends (1), loop ends
(2).
2. Position Attachment Strap hook ends (1) under the harness shoulder straps and loop ends (2) over energy
absorber covers as shown (Figure 20B).
3. Wrap loop straps over energy absorber cover and harness shoulder straps. Secure snugly with hoop straps.
First time or infrequent users of Self-Retracting Devices (SRDs) should review the "Safety Information" at
the beginning of this manual prior to use of the SRD.
4.0 Use
4.1 BEFORE EACH USE: Before each use of this fall protection equipment carefully inspect it to assure it is in good working
condition. Check for worn or damaged parts. Ensure all bolts are present and secure. Check that the lifeline is retracting
properly by pulling out the line and allowing it to slowly retract. If there is any hesitation in retraction the unit should be
removed from service and destroyed. Inspect the lifeline for cuts, frays, burns, crushing and corrosion. Check locking
action by pulling sharply on the line. See the Inspection and Maintenance Log (Table 3) for inspection details. Do not use
if inspection reveals an unsafe condition.
4.2 AFTER A FALL: Any equipment which has been subjected to the forces of arresting a fall or exhibits damage consistent
with the effect of fall arrest forces as described in Table 3, must be removed from service immediately and destroyed.
4.3 BODY SUPPORT: A full body harness must be worn when using SRDs.
4.4 MAKING CONNECTIONS: Figure 11 illustrates harness and anchorage connections for SRD Fall Arrest Systems. When
using a hook to make a connection, ensure roll-out cannot occur (see Figure 5). Do not use hooks or connectors that
will not completely close over the attachment object. Do not use non-locking snap hooks. The anchorage must meet the
anchorage strength requirements stated in Section 1. Follow the manufacturer's instructions supplied with each system
component.
