The dorsal D-ring, pigtail D-ring, or web loop are the primary attachments for which purpose?

• A. Fall arrest
• B. Work positioning
• C. Rescue operations
• D. Lanyard adjustments

Answer: (A)

The important idea here is where a fall-arrest system connects to the harness. The dorsal D-ring, pigtail D-ring, or web loop are designed as the primary points to attach your lanyard or deceleration device so that the force of a fall is taken along a safe load path and the body is kept in a proper, upright position during arrest. The dorsal back location is especially favored because it directs the forces upward and minimizes tipping or forward collapse. Some harness designs include a pigtail D-ring or a web loop as alternate attachment points, offering flexibility for different equipment configurations or rescue scenarios. While other rings and points exist for work positioning or specialized tasks, the primary purpose of these attachment points is fall arrest; lanyard adjustments themselves occur on the lanyard or deceleration device, not at the attachment point.
