A qualified person is never permitted to cross the restricted approach boundary.

• A. True
• B. False
• C. Only with supervisor
• D. Only during maintenance

Answer: (B)

Crossing the restricted approach boundary is not an absolute prohibition. This boundary marks where the shock and arc-flash hazards become present, and access there is controlled to those who are trained and equipped to handle the risk.

A qualified person may cross that boundary when the task requires proximity to exposed energized parts and all appropriate safety measures are in place. This includes being trained and authorized, following a documented safe work procedure or permit, ensuring the energy source is controlled or the hazard is otherwise mitigated, and using arc-rated PPE and proper tools. In short, crossing the boundary is allowed under controlled conditions, not forbidden in all cases.

So the statement that a qualified person is never permitted to cross the restricted boundary is not correct. It's not restricted to supervision or maintenance alone; authorized tasks with proper safeguards can involve crossing the boundary.
