On June 17, 2021, ANSI/ASSP approved the new 2021 revision of Z359.14, Safety Requirements for Self-Retracting Devices (SRDs) for Personal Fall Arrest and Rescue Systems. This revision supersedes the 2014 version. This is an important date for both manufacturers and end users when it comes to ANSI compliance while using self-retracting devices. In this white paper, we will review the changes to the Z359.14 standard as interpreted by FallTech and discuss the compliance timeline and what that means for equipment you are using today.
When we are dealing with SRLs, we have two main categories: Class A and Class B. The main difference between these are fall clearance. Fall clearance is the amount of distance that an SRL will allow you to fall before they stop you. When you identify your fall protection situation and you look at the most critical aspect of fall clearance, you may find that a Class A SRL gives you the ability to meet that distance.
