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 fi tness to safely absorb the shock from a fall arrest. Age
and fi tness 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.
IMPORTANT:
Do not use a body belt for free fall applications. See OSHA 1926.502 for guidelines.
4.4 MAKING
CONNECTIONS: Figure 9 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 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 2.2. Follow the manufacturer’s instructions supplied with each
system component.
4.5 OPERATION: Prior to use, inspect the SRL as described in section 5.0. Figure 10 illustrates system connections for typical
Nano-Lok SRL applications. Connect Nano-Lok SRL on the back of a Full Body Harness per the instruction in Section 3.
On harness mounted SRLs, connect the Hook or Carabiner to a suitable anchorage. Ensure connections are compatible
in size, shape, and strength. Ensure hooks are fully closed and locked. Once attached, the worker is free to move about
within the recommended working area at normal speeds. If a fall occurs the SRL will lock and arrest the fall. Upon rescue,
remove the SRL from use. When working with an SRL, always allow the lifeline to recoil back into the device under
control.
WARNING:
Do not tie or knot the lifeline. Avoid lifeline contact with sharp or abrasive surfaces. Inspect the lifeline
frequently for cuts, fraying, burns, or signs of chemical damage. Dirt, contaminants, and water can lower dielectric
properties of the lifeline. Use caution near power lines.
4.6
TWIN SRL INTERFACE 100% TIE-OFF: When two Nano-Lok SRLs are mounted side-by-side on the back of a Full
Body Harness, the SRL Fall Arrest System can be used for continuous fall protection (100 % tie-off) while ascending,
descending, or moving laterally (see Figure 11). With the Lanyard Leg of one SRL attached to an anchorage point, the
worker can move to a new location, attach the unused Lanyard Leg of the other SRL to another anchorage point, and then
disconnect from the original anchorage point. The sequence is repeated until the worker reaches the desired location.
Considerations for twin leg 100% tie-off applications include the following:
•
Never connect both SRL Lanyards to the same anchorage point (see Figure 11 A).
•
Connecting more than one connector into a single anchorage (ring or eye) can jeopardize compatibility of the
connection due to interaction between connectors and is not recommended.
•
Connection of each SRL Lanyard to a separate anchorage point is acceptable (Figure 11 B).
•
Each connection location must independently support 10 kN (2,248 lbs) or be an engineered system, as with a
Horizontal Lifeline.
•
Never connect more than one person at a time to the Twin SRL system (Figure 12).
•
Do not allow the Lanyards to become tangled or twisted together as this may prevent them from retracting.
•
Do not allow any lanyard to pass under arms or between legs during use.
4.7 HORIZONTAL
SYSTEMS: In applications where the Nano-Lok SRL is used in conjunction with a horizontal system
(i.e. Horizontal Lifeline, Horizontal I-Beams Trolley), the SRL and horizontal system components must be compatible.
Horizontal systems must be designed and installed under the supervision of a qualifi ed engineer. Consult the horizontal
system equipment manufacturer’s instructions for details.
5.0 INSPECTION
5.1
i-Safe™ RFID TAG: The Nano-Lok SRL includes an i-Safe™ Radio Frequency Identifi cation (RFID) tag (see Figure 15).
The RFID tag can be used in conjunction with the i-Safe handheld reading device to simplify inspection and inventory
control and provide records for your fall protection equipment. If you are a fi rst-time user, contact a Capital Safety
Customer Service representative (see back cover); or if you have already registered, go to isafe.capitalsafety.com. Follow
the instructions provided with your i-Safe handheld reader or software to transfer your data to your database.
