What is important when stacking loads on top of each other to maintain stability?

• A. Heavy and/or Liquid goods at the bottom
• B. Firm Level Surface
• C. High loads may be unstable
• D. All of the above

Answer: (B)

Stability starts with the base. A firm, level surface provides a solid foundation for stacked loads, preventing contact points from shifting as you move, lift, or brake. When the base is flat and hard, each pallet sits securely and the load above remains aligned, reducing the risk of tipping. The other practices—placing heavier or liquid items lower and recognizing that tall stacks can be unstable—are important, but they rely on having a solid base. If the surface is uneven or soft, no amount of careful stacking can guarantee stability because the stack won’t have a true point of support. So the most fundamental condition to maintain stability when stacking is a firm level surface.
