What must you do to keep unqualified people from entering an electrical work area?

• A. Post a sign only
• B. Barricade the area; rope off
• C. Lock the door and leave
• D. Ignore; they won't come

Answer: (B)

Controlling access to the electrical work area is about preventing unqualified people from entering. The most reliable way to do this is to create a visible, physical boundary that people cannot casually cross. Barricading the area and rope‑off lines establish a clear, substantial barrier that signals and enforces restricted access, making it much harder for someone unqualified to wander in. Signs alone may warn, but they don’t physically prevent entry, and a door alone can be bypassed or opened by mistake. A barrier around the space provides a consistent, enforceable limit to entry and helps protect workers from electrical hazards by keeping the area off-limits to those without proper authorization and training.
