What is the minimum approach distance while walking over and around an energized Third Rail?

• A. 6 inches.
• B. 4 feet.
• C. 3 ft.
• D. 15 ft.

Answer: (A)

Electric safety around the energized third rail hinges on maintaining a strict clearance to prevent shock or an arc path. The six-inch buffer provides a practical, minimum distance that reduces the chance of accidental contact if you slip or your footing isn’t perfect, and it minimizes the risk of a harmful current path through your body if there’s any fault or moisture. Other distances aren’t necessary for this scenario: they’re larger than the required minimum and can hinder movement, while being closer than six inches would raise the risk of contact. So, the best practice is to keep about six inches of clearance when walking over and around an energized third rail.
