Minimum Approach Distance means:

• A. The maximum distance a worker can approach live parts
• B. The closest distance a worker can approach exposed live parts without special protective equipment or a live-line barrier
• C. The distance to keep from other workers
• D. The recommended distance to stay away from water

Answer: (B)

The minimum safe approach distance is the closest distance a worker may approach exposed live parts without using special protective equipment or a live-line barrier. This boundary is set to prevent electric shock and arcing by ensuring you stay far enough away from energized parts unless you’re protected. If you need to get closer, you must de-energize the equipment or use appropriate PPE and barriers and follow the required procedures. This distance varies with voltage and conditions and is a standard safety measure in electrical work.

The other options don’t fit because they describe distances that aren’t about electrical live parts: maximum distance isn’t the concept, distance to other workers isn’t about live parts, and distance from water isn’t relevant to approaching energized equipment.
