When working underneath energized conductors, what should always be observed?

• A. Zoning compliance
• B. No clearance requirements
• C. Safe work distances
• D. Close approach for efficiency

Answer: (C)

Safe work distances must be observed whenever energized conductors are nearby. Maintaining a prescribed minimum separation creates a protective buffer that helps prevent accidental contact with live parts and reduces the severity of an arc flash if something slips or a tool contacts the conductor. Even when you’re working under lines, this boundary helps protect you from shock and burns and guides how you set up your work zone, use barriers, and coordinate with de-energization procedures when possible. If you cannot keep the safe distance, the proper action is to de-energize or isolate the circuit and follow established safety procedures, rather than relying on proximity for efficiency. Zoning compliance is unrelated to live-conductor clearance, there are indeed clearance requirements, and getting too close for efficiency is dangerous and not allowed.
