Explore the Ins and Outs of Self-Retracting Lifelines! You have a lot of options when it comes to fall protection devices, and one of those options is self-retracting lifelines. Known also as SRLs, automatic fall arrest devices, retractable fall arresters, retracting lanyards, and fall arrest blocks, SRL is a type of retracting lanyard used in conjunction with a harness and anchorage point. They can be used 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 has occurred. Explore the ins and outs of SRLs and Safe Keeper’s inventory of SRLs. SRLs Defined A common analogy given to explain the working of an SRL 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 will 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, theorizing mechanism is the SRL will seize up if a worker falls, effectively stopping the fall and keeping the wearer from injury or death. Safe Keeper’s SRLs Safe Keeper carries an extensive inventory of self-retracting lifelines. We have SRLs that are 6-foot, 10-ft, 11-foot, 18-foot, 20-foot, 25-foot, and 30-foot in length. We carry dual SRLs, lightweight SRLs, leading edge SRLs, galvanized cable SRLs, and web SRLs. All of our SRLs meet or exceed OSHA and ANSI standards. Safe Keeper also carries harnesses, anchorage, and other fall protection products and accessories so that you can tailor your fall protection system to meet your needs.
