Minimum and maximum scaffold plank overhang beyond end support is?

• A. 3 inches; 9 inches
• B. 6 inches; 12 inches
• C. 8 inches; 16 inches
• D. 4 inches; 8 inches

Answer: (B)

Overhang limits on scaffold planks control how much of the plank can extend beyond the end support to keep the plank stable and give you a safe working edge. The overhang must be enough so you have secure footing and proper engagement with the end support, but not so much that the plank becomes unstable or bends under load. The standard sets a minimum of six inches beyond the end support to ensure the end of the plank is well supported and you have a usable edge for stepping and balance. It also caps the overhang at twelve inches to prevent excessive unsupported length, which could cause the plank to bend, slip, or fail and increase the risk of a fall. So the safe, correct range is six inches to twelve inches. Ranges shorter than six inches don’t provide adequate edge support, while ranges longer than twelve inches create greater danger of plank failure and loss of balance.
