Safety Recall: 3M Pulls Twin Leg Self-Retracting Lifelines

By Art Aisner, Editor-in-Chief

3M Fall Protection announces an immediate stop use and product recall of the 3M™ DBI-SALA® Nano-Lok™ edge and Wrap Back Twin-Leg Self Retracting Lifelines.

The twin-leg Nano-Lok edge is part of a personal fall protection system and connects two self-retracting lifelines/devices (SRL’s/SRD’s) directly under the dorsal d-ring of a worker’s harness. It is intended to be anchored at foot-level, and is designed for sharp edge applications. The twin-leg Wrap Back Nano-Lok is intended for wrapping around an anchor and incorporates a similar energy absorber. 3M has determined that in the event of a fall and under certain conditions, the energy absorber may not properly deploy which could expose the worker to serious injury or death.

Although there have been no reports of accidents or injuries associated with this issue, these products must be removed from service immediately. To address this situation in the interests of worker safety, 3M is launching a global stop use of the Nano-Lok edge and Wrap Back Twin-Leg SRL units and is recalling all these units to be repaired or replaced as soon as a solution is identified, tested and certified. In the interim, and until a repair or replacement is available, end-users may elect to receive cash for their returned units as described below.

This stop use and recall affects all versions of the Nano-Lok edge and Wrap Back Twin-Leg SRL’s since first introduced in 2013; it does not include Single-leg versions of these models. Users/owners should stop using affected Nano-Loks immediately and take them out of service. At this time, these users/owners can choose to receive a free, new or repaired Nano-Lok or $200 for each affected Nano-Lok they own.
