Applicable Standards
ANSI Standard Update: Breaking It All Down Below is comparison of a few of the differences between the current and revised standard. The full text is available for purchase at https://webstore.ansi.org/Standards/ASSE/ANSIASSPZ359142021 . Current Revised SRD: General term used to describe three types of devices SRD: General term used to describe three types of devices Devices Types: SRL, SRL-R, SRL-LE Devices Types: SRL, SRL-R, SRL-P Two Classes that apply to the SRL, & SRL-R. Two Classes that apply to ALL SRD's Classes (A & B) specify performance requirements & arrest distances under specific testing conditions Classes (1 & 2) specify conditions for use of devices based on application and potential risk New Device Type: SRL-P - Self Retracting Lanyard, Personal While "Personal SRL" has been a term in the industry for years, it was considered an unofficial subset of general SRLs and not categorized as a device type. The new standard introduces an official SRL-P type with new testing requirements to encourage safe use by the end-user. (See Pages 16 & 17) Leading Edge Devices VS. Class 2 Devices The SRL-LE device type has been removed in favor of an all-encompassing Class system that is used for all SRD types. For example, instead of a Personal device being classified as a SRL-LE, it will instead be considered a Class 2 SRL-P. This also opens the possibility for SRL's and SRL-R's to be considered Class 2 should they pass the testing requirements. Please note: not all current SRL-LE devices on the market will meet the Class 2 requirements. (See Pages 16 & 17) Additional Changes There are additional testing requirements that are included to improve factors of safety in an effort to address predicable vulnerabilities. These include: • An energy capacity test for Class 1 SRL-P's requiring them to be subjected to a six-foot vertical free fall while limiting arrest forces and arrest distance. • A battery of tests for dual-configuration SRL-P's to qualify them in a manner similar to the conditions the dual energy-absorbing lanyards are subjected to in Z359.13. • Specific testing requirements for the connecting element used to affix SRL-Ps to full body harnesses. • A locking strength test for SRDs relying on textile energy absorbers to manage arresting forces. The requirements for markings and instructions also feature some key updates, which include: • More detailed disclosures with respect to arrest distances and clearance requirements. • SRD class icons similar in nature to the marking requirements for energy-absorbing lanyards. • Explicit warnings regarding the hazards associated with foot-level tie-off and contact with structural edges. As previously stated, the revised standard does not go into effect until August 2022, and may be subject to change. See pages 16 & 17 of this guide for revised definitions and classes.
