If cables are present on only one side of a workspace, what is the minimum clear workspace required?

• A. 1 foot
• B. 2 feet
• C. 3 feet
• D. 4 feet

Answer: (B)

The main idea is to have enough unobstructed space to work safely when cables sit on only one side of the area. With cables on one side, you need a clear pocket on the opposite side to stand, move, and operate tools without brushing against the cables or feeling cramped. Two feet provides a practical width that lets you reach panels, position equipment, and keep a margin in case a cable shifts or you need to maneuver around an object. One foot is generally too tight for safe hand movement and passage. Three or four feet would be comfortable but isn’t the minimum needed for a single-side arrangement, making two feet the appropriate minimum.
