Incorrect Use: Additional factors to avoid, shown in Figure 12:
Do not allow the lifeline to drape over and edge during normal work as this may abrade, damage, or otherwise compromise the lifeline.
Do not attach the anchor on one side of an opening and work on the other side, as this creates multiple possible leading edges and
potential swing fall hazards.
5.6
Operation of the SRD: Before each use, inspect the SRD, see Section 7 for inspection instructions.
5.6.1
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. Beware of
Leading Edge hazards.
DO NOT attach an additional shock absorbing lanyard or similar device between the SRD housing and the anchorage.
5.6.2
Fall Arrest Impact Indicator: The primary fall arrest impact indicator is the load-indicating Energy Absorber. The Energy Absorber will
display a red and white band if it has been subjected to fall arrest, or equal, forces, as shown in Figure 13, Image B. If the Energy Absorber
shows any sign of damage, torn or ripped cover, frayed thread, burns or trauma of any kind, remove the unit from service.
