Anchorage Connector
An anchorage connector is the engineered hardware or assembly that links a worker's fall protection or rope access system to a structural anchorage, such as a beam or slab. It is not the structure itself but the interface device, designed to meet standards like CSA Z259.15 or ANSI Z359, with a minimum breaking strength of 5,000 lb for fall arrest. It ensures secure attachment for travel restraint, fall arrest, work positioning, or suspended systems.
On a manufacturing shop floor, anchorage connectors are used for overhead fall arrest when working on machinery, tanks, or mezzanines. Common types include bolt-on D-ring plates, beam clamps, and roof anchors, installed per CSA Z259.15. For rope access, they connect working and rescue ropes to independent structural points. In suspended work platforms, they secure suspension lines and lifelines. SafeDesk compliance involves inventorying connectors, verifying CSA/ANSI labels, and ensuring installation by a qualified person. Each personal fall protection system requires its own connector, and the anchorage must support at least twice the expected load or 5,000 lb per user.
What minimum strength and design criteria apply to anchorage connectors under Canadian standards for typical fall arrest in a plant?
Under CSA Z259.15, anchorage connectors must meet performance, design, and testing requirements. Typical practice includes a breaking strength of at least 22.2 kN (5,000 lb) for personal fall arrest, with a safety factor of 2x the maximum arresting force. Documentation should record rated capacity and intended use class, ensuring the anchorage substrate can sustain these loads.
How should anchorage connectors be selected and laid out according to WorkSafeBC guidance?
WorkSafeBC Part 11 recommends considering fall distance and swing fall when locating connectors. Select connectors meeting CSA or ANSI standards with clear labeling. Position them above the worker to minimize free fall, and use separate connectors for primary and backup systems or for each worker, as per regulations.
What are the inspection and marking expectations for anchorage connectors?
CSA Z259.15 requires marking of manufacturer, model, rated capacity, and applicable standard (e.g., 'CSA Z259.15'). WorkSafeBC mandates that the standard name appear on the label. Inspect for legible markings; remove connectors with missing or inconsistent labels from service and review by engineering.
