Self-Retracting Lifelines

Explore the Ins and Outs of Self-Retracting Lifelines!

You have many options when it comes to fall protection devices, and one of those options is self-retracting lifelines. SRLs are also known as automatic fall arrest devices, retractable fall arresters, retracting lanyards, and fall arrest blocks. An SRL is a retracting lanyard used in conjunction with a harness and anchorage point. Workers can use them in fall restraint situations—keeping the worker from approaching an edge or other fall hazard—and fall arrest situations—stopping a falling worker after the fall. Explore the ins and outs of SRLs and Safe Keeper’s inventory of SRLs.

SRLs Defined

A common analogy to explain an SRL’s working is a seat belt. When a seat belt is pulled out gently, it lets out more material as needed, and it will retract any slack in the belt. But when a seat belt is pulled out with force, such as during a car crash, the locking mechanism in the seat belt seizes, keeping the wearer restrained in the seat.

SRLs work in the same way. They will roll out to let a worker walk around the workspace and gently retract any slack in the line. In fall restraint situations, the SRL should be shorter than the distance from the anchorage to the fall hazard, such as the edge of a building, and will thus not let the wearer get near the edge. In fall arrest situations, the theorizing mechanism is the SRL will seize up if a worker falls, effectively stopping the fall and keeping the wearer from injury or death.
