Which of the following is a primary attachment for fall arrest?

• A. Dorsal D-ring
• B. Shoulder D-ring
• C. Sternal D-ring
• D. Rear anchor

Answer: (A)

The key idea is how fall-arrest loads are best directed through the body. The dorsal D-ring sits at the center of the back on a full‑body harness, so when a fall is arrested the force travels along the spine and hips. This orientation helps keep you upright and minimizes dangerous chest or abdominal compression, reducing injury risk during deceleration. Front attachment points, like the shoulder or sternum rings, are used for other tasks such as work positioning or restraint; in a fall they can pull you forward or expose the chest to greater risk, so they’re not the preferred point for arrest. The rear anchor refers to where the lanyard is tied off, not the harness connection point itself, so it isn’t the primary point for arrest. That’s why the dorsal D-ring is the best answer for fall arrest.
