5.5 Operation of the SRD: Before each use, inspect the SRL-R. See Section 7 for inspection instructions.
5.5.1 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.
DO NOT attach an additional shock absorbing lanyard or similar device between the SRD housing and the anchorage.
5.5.2 Fall Arrest Impact Indicator: The primary fall arrest impact indicator is the load-indicating leg-end connector. The connector will
display a red band if it has been subjected to fall arrest, or equal, forces, as shown in Figure 25, if the snap hook shows any sign of
damage, remove the unit from service.
