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 7). 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. When working with an SRL, always allow
the lifeline to recoil back into the device under control. 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 and conditions, it may be
necessary to restrain the free end of the tag line to prevent interference and entanglement with equipment
or machinery.
WARNING:
Do not tie or knot lifeline. Avoid lifeline contact with sharp or abrasive surfaces. Inspect 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 RETRIEVAL OPERATION:
Figure 9 illustrates operation of the Integral Rescue Hand Crank on Sealed-Blok
Retrieval SRL-Rs. To activate Retrieval mode and use the Rescue Hand Crank:
1. Loosen the Locking Thumb Screw to release the Crank Arm.
2. Rotate the Retrieval Handle up from the SRL Body 90°.
3. Pull and hold the Shift Knob in the unlocked position.
4. Push the Crank Arm in and release the Shift Knob to engage. If needed, rotate the Crank Arm clockwise
to help engage the gear.
5. Raise and lower the Lifeline as illustrated in Figure 9:
A. To Raise: Rotate the Crank Arm counterclockwise.
B. To Lower: Rotate the Crank Arm clockwise. After Fall Arrest; crank the Crank Arm counterclockwise
slightly first to release the Fall Arrest Brake, then crank the Crank Arm clockwise.
RETRIEVAL OVERLOAD:
Sealed‑Blok SRL‑Rs do not incorporate an Overload Clutch to limit the force exerted on the
drive components and attached person. Avoid line slack while in Retrieval mode. Also, monitor the individual during retrieval
to ensure they are not subjected to excessive force from continued lifting after entanglement on an obstruction.
NOTE:
A minimum load of 75 lbs (33.9 kg) is required to lower or pay out the Lifeline. A force of 30 lbs (0.13 kN) is required
to operate the Retrieval system when loaded to capacity.
CAUTION:
Stop cranking when the Lifeline is fully extended or retracted. Continued cranking can damage components.
4.7 RETRIEVAL DISENGAGEMENT:
To disengage Retrieval mode:
CAUTION:
When Retrieval mode is disengaged, any extended Lifeline will retract into the SRL. To avoid possible
injury, retract the Lifeline prior to disengagement or hold onto the Lifeline.
1. Remove any load from the Lifeline.
2. Pull and hold the Shift Knob in the unlocked position.
3. Pull the Crank Arm out to disengage and then release the Shift Knob.
4. Pull out and rotate the Retrieval Handle down toward the SRL Body to stowed position.
