Work within the arc flash boundary of overhead lines requires compliance with which categories of requirements?

• A. I, II, and III
• B. I, II, III, IV, V, and VI
• C. I, II, IV
• D. I, II, III, IV, and V

Answer: (B)

When you work inside the arc flash boundary around overhead lines, you must apply a complete protection program that covers every aspect of safety, not just one or two elements. The boundary defines a potential energy release scenario, so risk must be addressed through multiple, interlocking controls: hazard recognition and assessment, protective measures and engineering controls, the appropriate personal protective equipment, administrative controls and safe work practices, required training and qualifications, and proper documentation or job planning. Each category addresses a different angle of protection, and skipping any one leaves a gap that could still expose workers to serious harm. Therefore, the option that includes all six categories is the correct choice, as overhead-line work truly requires the full spectrum of requirements to manage arc-flash risk effectively.
