CSA Changes to SRL Leading Edge Standards in EWPs
1. Stricter Testing for Leading Edge Applications
-
CSA Z259.2.2 (SRLs) was updated to require specific leading edge (LE) testing.
-
SRLs now need to be rated for use over sharp or abrasive edges (like steel decking or concrete).
-
If an SRL is not marked “LE,” it cannot legally be used where the lifeline may contact an edge.
2. Clarification on Use in EWPs
-
Workers in boom lifts and other EWPs often anchor SRLs at foot level, which creates a higher risk of the line running over an edge.
-
CSA now requires that SRLs used in EWPs be explicitly tested and approved for leading edge use.
-
This ensures the lifeline can withstand edge abrasion and the increased fall forces that occur with foot-level anchorage.
3. Energy Absorption Requirements
-
The standard emphasizes the need for energy-absorbing components in SRLs used in LE applications.
-
This helps limit arresting forces on the worker and reduces stress on the lifeline when falls occur near edges.
4. Labelling & Marking Changes
-
Approved SRLs must now carry clear labels indicating “Leading Edge” or “LE approved.”
-
This makes it easier for safety managers and workers to quickly confirm the right equipment is in use.
5. Employer Responsibilities
-
Employers must ensure SRLs are matched to the work environment — not just any SRL can be used in an EWP.
-
Training is required so workers understand the difference between standard and LE-rated SRLs.
✅ In summary: Under the new CSA standard, when working in an EWP, only Leading Edge-rated SRLs can be used, as they are specifically tested for the edge hazards and foot-level anchorage common in these applications. This change provides greater assurance of fall protection safety and reduces the risk of lifeline failure in real-world conditions.
