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 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 defined 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.
;
Do not tie off in dotted area of clearance charts (Figure 4).
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 sufficient 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 (G) 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 figure 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.
6.
Web Loop Harness Adapter: The Nano-Lok Edge SRL-LE Web Loop Harness Adapter (P/N 3500046) (see Figure
21) is a web loop that allows the SRL-LE to be used on harnesses that are not compatible with the SRL-LE Harness
Interface connector. This applies primarily to harnesses with fixed D-Rings that do no have enough slack in the
harness web to allow the pin of the connector to pass through.
Step 1: Position harness D-Ring (1) as shown.
Step 2: From behind and at the bottom of the D-Ring, insert the Web Loop up through the D-Ring and
fold the top of the loop down (2).
Step 3: Pull the top of Web Loop (3) down through the bottom of the Web Loop.
Step 4: Open the Nano-Lok Edge SRL-LE Harness Interface. Push down on the Locking Buttons (4)
simultaneously and slide the Locking Pin (5) out. Position the Web Loop between the sides of the
Harness Interface as shown.
Step 5: Insert the Locking Pin (6) Through the Web Loop. Confirm that the Locking Pin has locked in
the closed position. If properly closed, the Red Band on the Locking Pin will not be visible.
