On July 25, 2019, 3M Fall Protection announced an immediate stop use and product recall of the 3M DBI-SALA Twin-Leg Nano-Lok edge and the Twin-Leg Nano-Lok Wrap Back Self-Retracting Lifelines. 3M determined that in a fall and under certain conditions, the energy absorber of these devices may not properly deploy which could expose the worker to serious injury or death. There have been no reports of accidents or injuries associated with this issue, but these products must be removed from service immediately.
The Twin-Leg Nano-Loks are used as part of a personal fall protection system that connects two self-retracting lifelines/devices (SRLs/SRDs) directly under the dorsal D-ring of a worker’s harness. The Twin-Leg Nano-Lok edge is intended to be anchored at foot-level, is designed for sharp and/or leading edge applications and incorporates an energy absorber. The Twin-Leg Nano-Lok Wrap Back is intended for wrapping around an anchor and incorporates a similar energy absorber. 3M has determined that in a fall and under certain conditions, the energy absorber of these devices may not properly deploy which could expose the worker to serious injury or death.
To address this situation, in the interests of worker safety, 3M is launching a global stop use of the Twin-Leg Nano-Lok edge and Twin-Leg Nano-Lok Wrap Back SRL devices. It is recalling all these devices to be repaired or replaced as soon as a solution is identified, tested and certified. Alternatively, end users may elect to receive cash for their returned devices as described below. This stop use/recall affects all models of the Twin-Leg Nano-Lok edge and Twin-Leg Wrap Back SRLs since first introduced in 2013. This stop use/recall does not affect the single-leg versions of these models.
In a separate notice, 3M announced it has resolved the partial deployment of the energy absorber that led to the immediate stop use and recall of the Twin-Leg Nano-Lok edge SRL*. A robust solution has been identified, tested and certified to the ANSI standard Z359.14. With this solution, the energy absorber of these units will deploy properly under all circumstances of use for which these products are intended. The affected units can now be repaired and safely returned to service. Due to regional regulatory requirements, this solution is currently available only in regions that recognize the ANSI standard. Until your unit has been repaired or replaced as described above, the “Stop Use and Recall” remains in effect and these units must be removed from service.
3M urges users/owners of the affected products to immediately stop use and take the devices out of service. Next, go to www.NanoLokEdgeRecall.com and follow the instructions on how to return your device. As soon as a product solution is available, 3M will either repair or replace your device and return it to you at 3M’s expense. Alternatively, and only until a repair or replacement solution is available, you can return your device and elect to receive cash in the amount of $400 USD if your device was manufactured after January 1, 2017, or $200 USD if your device was manufactured before January 1, 2017. The manufacture year/month is printed on the back label of the device.
* Note: At the time of this update, the solution does not include the Twin-Leg Nano-Lok Wrap Back SRL or the Twin-Leg Nano-Lok edge Tie Back versions.
