Which material is NOT typically found in Non Bulk Packaging?

Non-bulk packaging is specifically designed for smaller quantities of hazardous materials and includes packaging types like drums, boxes, bags, and cartridges. Fixed tanks, on the other hand, are considered bulk storage containers. They hold larger volumes of materials and are typically stationary, permanently installed at a site, such as in a facility or an industrial complex.

In contrast, compressed gas cylinders, fertilizers, and ammonium nitrate can all be found in non-bulk packaging in smaller, manageable quantities. These materials can be shipped in various forms suitable for non-bulk packaging standards because they are often managed at lower volumes, which aligns with the non-bulk classification. Therefore, fixed tanks do not fit the criteria for non-bulk packaging, making it the correct answer.
