130.9 deals with requirements for work within the limited approach boundary or arc flash boundary of overhead lines. True or False?

• A. True
• B. False
• C. Not applicable
• D. Needs further clarification

Answer: (A)

The idea being tested is that safety rules in 130.9 focus on what must be done when work is performed inside the limited approach boundary or the arc flash boundary around energized parts, such as overhead lines. These boundaries mark where shock or arc flash hazards become significant, so the standard requires specific controls to protect workers. When work is inside these zones, de-energizing the equipment if possible is preferred, and if it must be performed energized, an energized work permit, a qualified person, and appropriate arc-rated PPE and procedures are required. The boundaries also dictate who can approach, what training is needed, and what protective measures must be in place. That’s why this statement is true: 130.9 governs the requirements for work within those boundaries around overhead lines.
