5.4.1 Locking Mechanism:
The SRD utilizes an acceleration based locking mechanism. The locking function requires a certain
payout rate during a fall event to function correctly. Certain situations, confined or cramped spaces,
shifting footing such as sand, gravel, grain, or a sloped surface may not allow the lifeline to reach
sufficient speed to activate the lock mechanism. A clear path is required to assure positive locking of
the SRD. Ensure the lock is functioning properly. Pull the lifeline out a short distance and give it a sharp
tug. The lifeline must lock. If it fails to lock, remove it from service immediately. Ensure the work zone
remains within stated parameters.
5.4.2 Visual Indicator:
The primary visual indicator is the shear connector. The shear connector halves will separate if the
SRL-P has been subjected to fall arrest forces, as shown in Figure 4, Image B. If the shear connector
is separated, remove the unit from service. For deployed visual indicators, both SRDs and the energy
absorber shall be removed from service and destroyed. SRD units shall not be salvaged and re-used
with other energy absorber(s).

5.4.3 After A Fall:
Ensure a written rescue plan, method and system is in place and readily available to all users for rapid
response. Ensure all users are trained in rescue procedures. If a fall event occurs, remove it from
service, and store it separately. Remove from service any unit that has been subjected to fall arrest
forces or that exhibits damage consistent with such forces. For questions, contact FallTech.
5.4.4 Using the SRD:
Do not use the SRD if inspection shows damage or any malfunction. Don the FBH in accordance
with the FBH manufacturer's instructions. Follow the instructions contained in this manual and on
the labels. Failure to follow instructions may result in serious injury or death. Connect the SRL-FBH
Connector to the dorsal D-ring on the FBH. Ensure the connector closes and locks. Attach the leg-end
carabiner to the chosen anchorage and ensure the leg-end connector closes and locks. Ensure all
connections are compatible. Normal operation will allow the working length of the lifeline to extend
and retract as the worker moves about. A certain amount of tension must remain on the web at all
times to ensure proper operation of the internal brake. Do not allow the lifeline to become slack.
If the lifeline becomes slack, remove the SRD from service for inspection. See Section 7.
Avoid sudden or quick movements during the normal work operation, as this may cause the SRD brake
to engage and possibly cause loss of balance and injury or death.
If a fall occurs, the brake will engage and lock the lifeline. The EA will deploy to arrest the fall and limit
arrest forces on the user.
•
DO NOT extend the lifeline past the operational limit.
•
DO NOT allow one SRD lifeline to become tangled or twisted with another SRD lifeline during use.
•
DO NOT allow any lifeline to pass under arms or between legs during use.
•
DO NOT clamp, knot, or prevent the lifeline from retracting or being taut.
•
DO NOT lengthen the SRD by connecting a lifeline or similar component.
•
DO NOT allow the lifeline to remain outside the housing when not in use.
