3M identified a potential cracking issue in the inner rope spool that may occur as a result of embrittlement over time of the plastic inner rope spool in all models; and after repetitive descents of the training model. This issue could impact the ability of a user to descend in the event of a fall.
University units in possession of 3M™ DBI-SALA® Self-Rescue Descent fall protection systems (part numbers 3320030, 3320031, and 3320037) should immediately remove these products from service.
