Definition – What does Self-Retracting Lanyard (SRL) mean?
A self-retracting lanyard (SRL) is a specific kind of lanyard used with a safety harness that utilizes inertia to activate a braking mechanism that is part of a block unit housed inside the body of the lanyard. This mechanism is typically activated when the fall distance exceeds four and a half feet per second. This inertia threshold activates a machined outer ring with spring-loaded arms that arrests the fall.
HSSE WORLD explains Self-Retracting Lanyard (SRL)
An advantage of a self-retracting lanyard over a shock-absorbing lanyard is that it only requires a maximum of two feet to arrest the fall instead of three and a half feet. In most cases, braking is almost instantaneous, which significantly reduces the risk of hitting the ground. Self-retracting lanyards are also easier to work within the event that a fall rescue must be undertaken. Generally, self-retracting lanyards are used in situations where a shock-absorbing lanyard would not be able to arrest the fall in time. SRLs are used when working off of ladders, in stairwells, and in scissor lifts.« Back to Glossary Index
