What sign indicates that a chain sling may be at end of service life?

Explanation:
The key idea is that a chain sling’s strength is compromised by physical damage and wear. Visible wear, elongation, bent links, cracks, or any deformation show the metal has fatigued or yielded under load, meaning the sling’s load rating is no longer reliable. This directly signals retirement to prevent a sudden failure during lifting. Cosmetic factors like fresh lubrication, a slight dull shine, or dustier appearance don’t reflect the chain’s structural integrity, so they don’t indicate it’s at end of service life.
