CSA Z259.2.5-17: Technical Requirements for Fall Arresters and Vertical Lifelines
A Comprehensive Guide to the Canadian Standard for Vertical Fall Arrest Systems
Fall protection in Canada is rigorously governed by the CSA Z259 series of standards. Among the most critical for workers ascending fixed ladders, towers, and vertical structures is CSA Z259.2.5-17, titled Fall arresters and vertical lifelines. This standard specifies the comprehensive requirements for guided-type fall arresters and their compatible vertical lifelines, covering design, dynamic and static performance, corrosion resistance, and marking. This article provides a technical breakdown of the standard’s scope, essential requirements, and practical implementation insights for the 2026 compliance landscape.
Scope of CSA Z259.2.5-17
CSA Z259.2.5-17 applies specifically to fall arresters that travel on a vertical lifeline and the lifelines themselves. This includes cable-based lifelines (typically galvanized or stainless steel) and synthetic rope lifelines (polyamide, polyester).
- Inclusions: Guided-type fall arresters, rigid rail systems, flexible vertical lifelines, and associated connectors.
- Exclusions: Self-retracting lifelines (SRLs) covered by CSA Z259.2.3, horizontal lifelines covered by CSA Z259.13, and full body
