SRD - General

(Figure 12.1)

Inspect for loose bolts and bent or damaged parts.

Inspect 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 Lifeline (C) should pull out and retract fully without hesitation or 

creating a slack line condition.
Ensure device locks up when lifeline is jerked sharply. Lockup should be 

positive with no slipping. 
Inspect the Housing Locking Pin (D) to ensure it is securely closed and 

locked around the harness shoulder straps. 
Inspect the hook and look straps (E) for excessive wear and operational 

security. 

Look for signs of corrosion on the entire unit.

Wire Rope Lifeline

(Figure 12.2)

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.

Web Lifelines

(Figure 12.3)

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.

Energy Absorber (Figure 13.1, 

13.2)

Verify that the integral energy absorber has not been activated. None of 

the Energy Absorber Webbing (C) should be exposed or pulled out from 

the Energy Absorber Cover (A). The Energy Absorber Cover (A) should also 

be secure and free of tears (D) or other damage. If the energy absorbing 

webbing (C) is visable or the SRL (E) is hanging down below the harness 

interface (F), the device must be removed from service.

Connectors

(Figure 13.3)

Inspect all SRD connectors for signs of damage and corrosion. Verify that 

all connectors are working properly. Where present: Gates (A) should open, 

close, lock, and unlock properly; locking buttons and pins should function 

correctly.

Labels (Figure 11)

All labels are present and fully legible.

Fall Protection Equipment

Additional Fall Protection equipment that is used with the product is 

installed and inspected per the manufacturer instructions.
