An energy-absorbing safety lanyard of the type that must be discarded once it has been subjected to a load greater than a maximum safe load comprises a core (14), a jacket (16) surrounding the core (14), and a flag (20) that is secured to the jacket (16) by break-away stitching. When, for example, the lanyard checks a man's fall, a load greater than the maximum safe load is applied to the lanyard and the core (14) stretches and generates a tension in the jacket (16). This tension pulls out the stitching and releases the flag (20), thereby showing that the lanyard should not be re-used. |
