APPENDIX A - SElf-REScuE TRAINING SYSTEM
L IMPORTANT: The Self-Rescue 50 System and Self-Rescue 100 System are single-descent systems. Once
used in a descent, they must be removed from service. Do not use the Self-Rescue 50 System or Self-Rescue
100 System for multiple descents as described in this Appendix. Only the Self-Rescue TRAINING System can be
used for multiple descents (for training only).
A.1 DESCRIPTION: The model 3320037 Self-Rescue TRAINING System is a multi-descent Self-Rescue Trainer
specifically for training personnel in a controlled training environment. It must be used with backup fall
protection (SRL with Descent, Belay Line, etc.). Up to 20 descents of 30 ft. (9 m) or less can be performed
with each Self-Rescue Trainer.
A.2 BEFORE EACH DESCENT: Review the Training Descent Log (Table 3) to confirm the Self-Rescue Trainer
has not reached its 20 descent limit. If the Self-Rescue Trainer has been used in 20 descents it should be
removed from service, marked as "UNUSABLE", and replaced. Contact 3M for replacement.
A.3 SETUP: Prior to each additional descent, the Self-Rescue Trainer must be reconfigured by a Competent
Person per the following steps (shown in Figure A1):
1
1. Detach the Self-Rescue Backpack from the Harness and open the Back Flap:
A. Push in the Locking Buttons on the Mounting Pin and pull out the Locking Pin.
B. Flip the Backpack over to access the Back Flap.
C. Unzip and open the Back Flap.
2. Unsnap and remove the Rope Spool from the Spool Cover.
A. Pull excess lifeline played out in the previous descent back through the Descent Device.
B. Pull on the rope rather than the Rope Spool to prevent the rope from pinching and binding in the
spool or damaging the spool flanges.
C. If rope binds inside the device, pull some of the lifeline back through the top and resume resetting
the device.
D. Inspect the Inner Spool Cylinder (Figure 17) for cracks, distortion, or other signs of wear specified in
the "Inspection and Maintenance Log". Remove from service if cracks are present.
3. Attach the Easy-Link D-Ring to the Latch Assembly on the Descent Device:
A. Slide the Latch Coupling on the Easy Link D-Ring over the Latch Arm.
B. Push down on the Latch Arm until the Plunger Pin clicks into place.
C. Route the Lifeline around the hinged end of the Latch Arm. Remove any slack in the loop terminating
the Lifeline to the Easy-Link D-Ring by pulling excess rope back through the Descender.
D. Keep slight tension on the terminating end while removing slack to avoid binding.
4. Rewind the excess Lifeline onto the Rope Spool and then snap the Rope Spool back into the Spool Cover.
5. If the Red Assisted Rescue Ring was used in the previous descent, reconnect the Assisted Rescue Cable
to the Release Cable. Make sure the cable and cable stop on the Release Cable are fully seated in the
slot in the Assisted Rescue Cable Clip.
6. Reposition the Release Cable under the Hook and Loop Flap on the Shoulder Strap and then close the
flap. Any excess cable should be loosely looped and tucked under the Hook and Loop Flap.
7. Loosely loop any excess cable from the Assisted Rescue Handle and tuck it inside the Hook and Loop
Flap along the inside wall of the Backpack. Reposition the Assisted Rescue Handle with the flanges of the
handle sandwiched between the two layers of the Backpack and the Red Assisted Rescue Ring protruding
out the side of the Backpack. Close the Hook and Loop Flap.
8. Pull up on the Easy-Link D-Ring to confirm the Latch Arm is fully latched.
A.4 INSPECTION: After setup and prior to each descent, the Self-Rescue Trainer must be inspected by a
Competent User per the procedures in the Inspection Checklist (Table 2).
A.5 AFTER EACH DESCENT: Record the descent in the Training Descent Log (Table 3).
