No approach of the MAD will take place unless which condition is true?

• A. You are insulated from the energized part
• B. The energized part is insulated
• C. Live line bare hand work is being performed
• D. Any of the above conditions is true

Answer: (D)

Minimum Approach Distance defines a safety boundary around energized parts that you should not cross unless specific protective conditions are in place. Being insulated from the energized part provides a barrier that prevents current from reaching you, so approaching within the boundary is considered safe under that protection. If the energized part itself is insulated, the energy cannot reach you even when closer, which also justifies closer work under controlled conditions. Live-line bare-hand work is a specialized method where trained workers use rigorous procedures and PPE to manage the energized conductor at close range. Each of these scenarios mitigates the risk enough to permit approaching within the MAD. Therefore, any one of these conditions being true allows work inside the MAD; if none are in place, you must maintain the full MAD.
