3.0 Installation
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 this manual.
3.2 ANCHORAGE: Figure 9 illustrates typical SRL anchorage connections. The anchorage (A) should be directly overhead to
minimize Free Fall and Swing Fall hazards (see Section 1). Select a rigid anchorage point capable of sustaining the static
loads defined in Section 1.4. The Swivel Eye on the SRL is equipped with a Carabiner (B). Attach the Carabiner directly to
the anchorage structure (rebar, angle iron, etc.), a Tie-Off Adaptor (C), or Anchorage Connection Point (D).
3.3 HARNESS CONNECTION: A Full Body Harness is required for Fall Arrest applications. Connect the Snap Hook (A) on
the SRL Lifeline to the Back Dorsal D-Ring (B) on the Full Body Harness. (see Figure 10). For situations such as ladder
climbing, it may be useful to connect to the front Sternal D-Ring. Consult the harness manufacturer's instructions for
details regarding use of the harness connection points.
3.4 MODULAR SRL-LE: SRL Model 3503848 is a LE SRL that contains a modular connector between the energy absorder and
Cable Lifeline. The Modular Connector (H) can be seen in Figure 2C. The modular connectors allow the energy absorber
(1246500) to be separated from the SRL. The modular connector eliminates the need to use a separate D-ring extension
between the Full Body Harness Dorsal D-Ring and the SRL snaphook. The energy absorber can remain on the user's back
and the user can detach the SRL lifeline using the modular connector. If the unit is subjected to a fall arrest, the full unit
(3503848) must be removed from service immediately, marked as "UNUSABLE," and inspected and serviced as instructed
in Section 5 and 6.
ASSEMBLING THE MODULAR COMPONENTS: (See Figure 11)
STEP 1: Orient the energy absorber female connector and the lifeline male connector. Only use energy absorber model
1246500 with SRL-LE models with modular connectors.
STEP 2: Press the female connector locks (C) on each side of the connector to unlock the device. Insert the male
connector and slide to the bottom of the female connector. Release both locks to capture the male connector. The female
connector locks must return to their fully extended position.
STEP 3: Pull the energy absorber and lifeline in opposite directions to fully seat the male connector. The male connector
must be securely locked in the position shown.
;
Do not use the modular lifeline assembly if the locks do not return to the fully extended position after following
Steps 1,2, and 3 in Figure 11. An example of a failed connection is shown. The lifeline male connector is not fully
inserted and locked within the energy absorber female connector. This is an unsafe condition and the modular lifeline
components must not be used.
4.0 OPERATION
;
First time or infrequent users of Smart Lock Self-Retracting Devices (SRDs) should review the "Safety Information"
at the beginning of this manual prior to use of the SRD.
;
Users must have a written Rescue Plan and the means at hand to implement it when using the equipment.
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
marked as "UNUSABLE" and returned to an authorized service center for service. 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, marked as
"UNUSABLE", and inspected and serviced as instructed in Sections 5 and 6.
4.3 BODY SUPPORT: A full body harness must be worn when using 3M 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 Sternal D-Ring.
Consult the harness manufacturer's instructions for details regarding use of the harness connection points.
4.4 MAKING CONNECTIONS: 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 mounting surface should meet the anchorage strength requirements stated in section 2.2. Follow the manufacturer's
instructions supplied with each system component.
4.5 OPERATION: Inspect the SRL as described in Section 5.0. Connect the SRL to a suitable anchorage or anchorage
connector as previously described. Connect the Self-Locking Snap Hook on the end of the lifeline to the Dorsal D-Ring on
the Full Body Harness (see Figure 10). Ensure connections are compatible in size, shape, and strength. Ensure hook is
fully closed and locked. Once attached, the worker is free to move about within the recommended working area at normal
speeds. A tag line may be required to extend or retract the lifeline during connection and disconnection operations. A tag
line can be used to prevent uncontrolled retraction of the lifeline into the SRL. Depending on the work site environment
