A(n) ________ is defined as a suspension system that allows a worker to descend in a controlled manner and, as needed, to stop at any point to perform work.

• A. Rope descent system
• B. Scaffold
• C. Harness
• D. Lanyard

Answer: (A)

This item tests understanding of equipment that lets a worker lower themselves along a rope in a controlled way and stop at specific points to work. A rope descent system is built for controlled movement and intermediate stops, using a rope, a brake or descender device, an anchor, and a harness so the worker can descend safely and pause where needed. A scaffold is a stationary elevated platform, not a rope-based descent method. A harness is protective equipment worn by the worker but doesn’t provide controlled descent on its own. A lanyard connects a harness to an anchor for fall protection, not for controlled descent and work stops. So the best choice is the rope descent system.
