Pass Fail
SRD
(Figure 12)
Inspect for loose fasteners and bent or damaged parts.
Inspect the Housing (A) for distortion, cracks, or other damage.
Inspect the Harness Interface (C) for distortion, cracks, or other damage. The
interface should pivot freely.
The Web or Cable Lifeline (B) should pull out and retract fully without
hesitation or creating a slack line condition.
Ensure the SRD locks up when the Lifeline is jerked sharply. Lockup should be
positive with no slipping.
All labels must be present and fully legible (see Figure 18).
Inspect the entire SRD for signs of corrosion.
Inspect the Harness Locking Pin (D) to ensure it is securely closed and locked
around the harness shoulder straps.
Inspect the Hook and Loop Straps (E) for excessive wear.
End Connectors
(Figure 13)
Table 1 identifies the End Connectors that should be included on your
Nano-Lok SRD model. Inspect all Snap Hooks, Carabiners, Rebar Hooks,
Interfaces, etc. for signs of damage, corrosion, and proper working condition.
Where present: Gates (A) should open, close, lock, and unlock properly.
Web Lifelines
(Figure 14)
Inspect Webbing and/or Rope Lifelines; material must be free of cuts (A),
frays (B), or broken fibers. Check for tears, abrasions, heavy soiling (C), mold,
burns (D), or discoloration. Inspect stitching; Check for pulled or cut stitches.
Broken stitches may be an indication that the Energy Absorber has been
impact loaded and must be removed from service.
Wire Rope Lifelines
(Figure 15)
Inspect wire rope for cuts, kinks (A), broken wires (B), bird-caging (C),
welding splatter, (D) corrosion, chemical contact areas, or severely abraded
areas. Slide the cable bumper up and inspect ferrules for cracks or damage
and inspect the wire rope for corrosion and broken wires. Replace the wire
rope assembly if there are six or more randomly distributed broken wires in
one lay, or three or more broken wires in one strand in one lay. A “lay” of wire
rope is the length of wire rope it takes for a strand (the larger groups of wires)
to complete one revolution or twist along the rope. Replace the wire rope
assembly if there are any broken wires within 1 inch (25 mm) of the ferrules.
Energy Absorber
(Figure 16)
Verify that the integral Energy Absorber has not been activated. An open cover
or torn cover (A), webbing pulled out of the cover, torn or frayed webbing,
ripped stitching, etc. are indicators of an activated Energy Absorber.
