What is a consequence of a single deviation failing?

The consequence of a single deviation failing being a small out of control swing refers to the dynamics of a rope access system and the nature of forces at play. Deviations are often used in rope access to change the direction of the rope and, consequently, the technician's position. If one of these deviations fails, it won't result in a catastrophic failure, as the other components of the system can still maintain tension and stability.

In the case of a single deviation failing, the technician may experience a shift in their trajectory or a minor swing due to the sudden release of tension on that particular path. This swing is likely to be small because other safety measures, such as the harness and the primary rope system, still provide a secure connection to the anchor points.

In scenarios where the failure of a single deviation could lead to other types of events like a complete fall or a large out of control swing, the overall assessment of equipment and redundant systems is designed to mitigate such severe consequences. Therefore, while it could result in a small out of control swing, the structural integrity of the remaining equipment and safety protocols helps prevent more dangerous outcomes.
