What is the minimum strength required for a rope access anchor?

The minimum strength required for a rope access anchor is 15 kN. This standard is established to ensure that the anchor can safely support loads during operations. A 15 kN minimum strength provides a safety margin that accommodates the dynamic forces experienced during a fall or other loading scenarios.

When working in rope access, it's critical to have reliable anchors because they are the foundation of safety while suspended. The strength threshold is developed considering potential shock loads that could occur in the event of a fall, which means the anchors must be capable of not only holding a static load but also absorbing dynamic forces effectively.

The other options present higher strength requirements, which, while they might be suitable for specific applications or environmental conditions, are not the minimum specified for routine rope access work. Therefore, while higher strength anchors may offer added safety margins, the established minimum for standard rope access applications is 15 kN.
