Which system must be flagged with highly visible materials at least every six feet?

• A. Guardrails
• B. Wire Rope Guardrails
• C. Harnesses
• D. Safety Nets

Answer: (B)

Wire rope guardrails create a boundary around edges to prevent falls, but the thin rope can be hard to see in busy or dim work areas. Flagging the rope with highly visible materials at least every six feet makes the edge clearly noticeable, helping workers recognize the boundary as they move and reducing the chance of accidentally stepping into a hazard. The six-foot spacing ensures constant visibility along long runs and around turns. Other options don’t fit because solid guardrails are usually clearly visible on their own, personal protective equipment like harnesses is worn by workers and doesn’t define an edge, and safety nets are used to catch falls rather than mark a boundary.
