What would result in removing a sling from service?

Removing a sling from service due to broken or worn stitches is essential for ensuring safety and operational integrity. The stitches are critical in holding the sling's layers together and maintaining its load-bearing capacity. When stitches become damaged, it compromises the sling's structural integrity, making it unsafe for lifting and rigging tasks. Regular inspections focus on the stitching because even a small defect can lead to a complete failure under load, posing serious safety risks.

While minor fraying, color fading, and the age of a sling may indicate wear and tear or reduced effectiveness, they do not immediately render the sling unsafe. Minor fraying could be a normal part of wear, and many slings are still effective despite fading. The age can serve as a guideline for inspection frequency and replacement, but it alone does not determine whether a sling is unsafe to use without visible signs of deterioration or damage. Therefore, the condition of the stitches is a more critical factor in deciding when to remove a sling from service.
