True or False? Severely overloaded or shock loaded sling legs can be kept in service as long as they pass a stress test.

• A. False
• B. True
• C. Not enough information
• D. Depends on testing method

Answer: (A)

A sling leg that has been severely overloaded or subjected to a shock load should be retired from service, even if it passes a stress test. Severe overload or a sudden shock can cause hidden damage—fatigue cracks, deformation, or hidden wear in fibers, strands, chains, or fittings—that may not be visible yet reduces remaining strength. A stress test can show the ability to bear a load at that moment, but it won’t reliably reveal latent damage or determine the remaining safe life after exposure to dynamic, peak forces. Following safety guidance, any sling leg that experiences overload or shock loading must be removed from service, tagged and documented, and replaced rather than reused, with inspection and the standards or manufacturer guidelines guiding the retirement decision.
