What is the maximum height for stacking empty pallets for longer storage?

The correct answer highlights the maximum height for stacking empty pallets for extended storage purposes, which is essential for maintaining safety and stability. Stacking pallets at the specified height ensures that they do not become unstable over time, potentially leading to accidents or damage to the pallets themselves.

The limit is set to prevent excessive vertical pressure on the pallets at the bottom of the stack, which can cause deformation or failure. Bundling pallets together reduces the likelihood of shifting during storage, thus preserving the structural integrity of the stack.

There are specific guidelines and industry best practices regarding how high empty pallets should be stacked to ensure effective storage while minimizing risk. Therefore, the specified height and bundle size reflect a practical approach to achieving safe and efficient utilization of storage space. The other options represent heights and bundle configurations that exceed acceptable safety standards or industry recommendations, which can compromise both safety and pallet integrity in storage scenarios.
