What is one guideline regarding the stacking of containers over 30 gallons in a storage area?

Guidelines regarding the stacking of containers, particularly those that hold hazardous materials like those over 30 gallons, are crucial for ensuring safety and preventing spills or accidents. One key guideline is that these larger containers must not be stacked one upon the other. This is primarily due to concerns about stability, weight distribution, and the risk of toppling. If these containers are stacked, there is an increased risk that the bottom container may fail or that the whole stack could become unstable, leading to potential spills and exposure to hazardous materials.

Additionally, regulations typically prioritize maintaining accessibility and reducing the risk of human error involved in retrieving or handling these large containers. This means that keeping them on the ground level can help minimize risks associated with lifting or moving heavy objects. Proper storage practices emphasize safety and compliance with regulatory standards, which often prohibit the stacking of large containers to mitigate the risks of an incident occurring.
