What wording on flags indicates electrical hazards requiring entry restriction?

• A. Authorized Personnel Only
• B. Keep Out
• C. Proceed with Caution
• D. Do Not Enter

Answer: (D)

Electrical hazard areas require a clearly prohibitive message so that no one automatically assumes it’s safe to enter. The phrase “Do Not Enter” gives an explicit, universal prohibition, leaving no ambiguity that access is forbidden due to danger until the area is secured and safe. That direct instruction is essential for preventing accidental entry into live circuits or other electrical risks. Other options don’t convey that absolute restriction as clearly. “Authorized Personnel Only” implies there’s a gate to entry but still leaves room for someone with authorization to enter, which isn’t suitable when immediate exclusion from the area is needed. “Keep Out” is strong but less standard in electrical safety signage and can be interpreted as a perimeter cue rather than a hard prohibition. “Proceed with Caution” explicitly invites entry with risk, which is inappropriate for high-voltage or live equipment. So the most effective wording to indicate electrical hazards requiring entry restriction is the direct command to stay out: Do Not Enter.
