What practice is required for used lumber before stacking?

• A. All nails must be withdrawn before stacking
• B. Nails may be left in place
• C. Lumber must never be stacked
• D. Nails should be bent but left in

Answer: (A)

Removing all nails from used lumber before stacking is essential because it eliminates snag hazards and reduces the risk of injuries during handling and piling. Nails left in place can catch on clothing, tools, or other boards, and can cause splinters or damage to the lumber and equipment. Stacking with embedded nails also makes piles unstable and difficult to manage. Even if nails are bent, they can protrude or break during movement, continuing to pose hazards. Therefore, the safe practice is to withdraw all nails before stacking.
