The correct response is that slings should never be shortened by knotting or twisting. Shortening slings in such a manner compromises their load-bearing capacity and introduces additional stress points, which can lead to failure.

When slings are knotting or twisting, it can cause a significant reduction in their strength due to the uneven distribution of load across the fibers. Knots can create weak points that lead to fraying or breaking, and twisting can introduce excessive wear and tear, potentially resulting in dangerous situations during lifting operations.

Proper rigging practices dictate that if a sling needs to be shortened, it should be done using appropriate hardware, such as adjustable slings or by using different rigging configurations that maintain the integrity of the sling's design and strength. This ensures safety during hoisting tasks and preserves the equipment's reliability.
