Interlocking rows should be used when stacking bags or bundles to minimize the risk of destabilization and falling, according to standard materials handling guidance. This technique helps distribute weight and prevents individual items from shifting, improving overall stability. Key points

• Appropriate materials: bagged materials and bundles are commonly stacked using interlocking rows. This approach is less applicable to cylindrical items like drums or barrels, which don’t interlock as effectively.
• Stability mechanism: interlocking rows create a staggered, braided-like configuration that resists lateral movement and tipping by transferring load between adjacent units.
• Best practices for implementation:
  • Stack in even, full-length rows to maintain uniform contact between items.
  • Cross-key or interlock the layers so each row locks into the row below.
  • Step back layers progressively to create a stable, masonry-like structure (where feasible).
  • Secure the top of the stack if necessary to prevent displacement by wind, handling, or vibration.
• Safety considerations:
  • Ensure load limits of shelving or pallets are not exceeded.
  • Use appropriate palletization and securing methods for transport and storage.
  • Inspect stacks periodically for shifting, damage, or compression.

If you’d like, I can tailor these guidelines to a specific material type or storage setup (e.g., warehouse pallet stacks, shelf-based storage, or transport scenarios) and provide a concise checklist.
