Which condition necessitates protection from falls such as guardrails, safety nets, or personal fall arrest systems?

• A. Unprotected sides and edges 6 feet (1.8 m) or more above a lower level
• B. Wet or slippery surfaces
• C. Working near high-voltage equipment
• D. Exposure to loud noise levels

Answer: (A)

Fall protection is required whenever there is a real risk of falling from an elevated area. When there are unprotected sides and edges six feet or more above a lower level, you must have some form of protection in place—such as guardrails, safety nets, or a personal fall arrest system. These measures are specifically designed to prevent a fall or stop it before a person reaches the lower surface, reducing the chance of serious injury.

The other hazards listed are important safety concerns in their own right, but they do not establish a fall-hazard scenario that requires fall protection equipment. Wet or slippery surfaces relate to slip-and-trip risks, not an elevated edge where a fall could occur. Working near high-voltage equipment and exposure to loud noise levels trigger different safety controls—electrical PPE and de-energizing practices for electrical hazards, and hearing protection for noise hazards.
