Which components are designed for fall arrest?

• A. Sternal and Dorsal rings
• B. Carabiners
• C. Harness waist belt
• D. Rope clamps

Answer: (A)

Attachment rings on a full‑body harness are the points designed to connect to fall protection gear such as lanyards and deceleration devices. The back (dorsal) ring is the primary attachment because placing the load there helps transfer the arrest force along the spine and across the torso, giving a safer and more controlled stop when a fall is arrested. The chest (sternal) ring can serve as an additional attachment point in certain configurations, offering alternative arrest or rescue options while still being part of a fall‑arrest system.

In contrast, a carabiner is just a connector and needs a lanyard or rope system to function for fall arrest; a waist belt by itself isn’t sufficient to arrest a fall; and rope clamps are used to manage rope movement or descent, not to stop a fall attached to a harness.
