Twin SRL Harness Interface:
In climbing applications where 100% tie-off is required, the Twin SRL
Harness Interface can be used to mount two Nano-Lok SRLs side-by-side on the back of a Full Body
Harness just below the Dorsal D-Ring (see Figure 9). To mount two Nano-Lok SRLs on a Full Body
Harness with the Twin SRL Harness Interface:
1. Loosen the Harness Webbing:
Pull out on the Web Straps (A) where they pass through the
bottom of the Dorsal D-Ring (B) until there is sufficient space to slide the Twin Leg Interface
between the Web Straps and D-Ring Pad.
2. Open the Harness Interface:
Push up on the Connector Insert (C) to unsnap the Clamps (D) from
the Connector and then swing the Connector Insert up to unlock the Gate. Push the Gate (E) inward
to open the Connector.
3.
Thread the first Nano-Lok SRL onto the Harness Interface:
Insert the Nose of the Connector
(F) through the Swivel Eye (G) on the SRL and then rotate the SRL around to the Gate End of the
Connector (H). The Gate can be rotated toward the Nose to allow clearance for the Swivel Eye
between the Gate and Spine of the Connector.
4. Position the Harness Interface around the Web Straps:
With the Gate facing up, insert the
Nose of the Connector (F) behind the Web Straps (A). Rotate the Connector behind the Web Straps
until the Connector surrounds the the Web Straps.
5. Add the second Nano-Lok SRL on the Harness Interface:
Slide the SRL’s Swivel Eye (G) over
the Nose of the Connector (F) and position the SRL Swivel Eye in the Nose End of the Connector (I).
Swing the Gate (E) closed.
6. Close the Harness Interface:
Rotate the Connector Insert (C) forward so the Clamps (D) secure
on the Connector. When properly closed, the Web Straps should pass through the Webbing Slot (J)
at the top of the Connector Insert and the SRL Swivel Eyes should be secured in the Recesses (K)
on either side of the Connector Insert. Once the Harness Interface is closed, pull the Web Straps (A)
back through the Dorsal D-Ring and D-Ring Pad to eliminate slack in the webbing and secure the
Connector between the Web Straps and D-Ring Pad.
NOTE:
Older ExoFit harnesses may require a different Twin SRL Harness Interface. See Appendix A.
4.0 USE
WARNING:
Do not alter or intentionally misuse this equipment. Consult Capital Safety when using this
equipment in combination with components or subsystems other than those described in this manual. Some
subsystem and component combinations may interfere with the operation of this equipment. Use caution when
using this equipment around moving machinery, electrical hazards, chemical hazards, sharp edges, or overhead
materials that may fall onto the lifeline. Do not loop the lifeline around small structural members. Failure to heed
this warning may result in equipment malfunction, serious injury, or death.
WARNING:
Consult your doctor if there is reason to doubt your fitness to safely absorb the shock from a fall
arrest. Age and fitness seriously affect a worker’s ability to withstand falls. Pregnant women or minors must not
use DBI-SALA self retracting lifelines.
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 Section 5 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 Section 5, must be removed from
service immediately and destroyed.
4.3 BODY SUPPORT:
A full body harness must be worn when using Nano-Lok SRLs. For general fall protection
use, connect to the back (dorsal) D-ring. For situations such as ladder climbing, it may be useful to connect
to the front of the harness above the worker’s center of gravity. This is acceptable provided potential free fall
is less than 2 ft. (61 cm) and footing can be easily regained.
IMPORTANT:
Do not use a body belt for free fall applications. See OSHA 1926.502 for guidelines.
4.4 MAKING CONNECTIONS:
Figure 10 illustrates harness and anchorage connections for Nano-Lok SRL Fall
Arrest Systems. When using a hook to make a connection, ensure roll-out cannot occur (see Figure 4). 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 2.2.
Follow the manufacturer’s instructions supplied with each system component.
