Which lanyard characteristic is associated with self-retracting lanyards?

Self-retracting lanyards (SRLs) are designed to automatically retract and take up slack in the line as a worker moves within their work area. This characteristic is crucial because it helps ensure that there is minimal slack in the lanyard at all times, which reduces the risk of falls and improves safety by keeping the line taut. A taut line minimizes the distance a worker would fall in the event of a slip or accident, thereby reducing the impact force and potential injury during a fall.

While other characteristics related to lanyards may be important, the unique ability of self-retracting lanyards to eliminate slack is what distinguishes them from traditional lanyards. This feature allows for greater mobility on a job site while maintaining safety, making SRLs a preferred choice for many construction applications.
