Bags, drums and cylinders are types of which packaging?

• A. Nonbulk
• B. Bulk
• C. Primary
• D. Secondary

Answer: (A)

Understanding packaging categories for hazmat transport is key here. Nonbulk packaging covers the individual containers used to ship hazardous materials in smaller, separable units. Bags, drums, and cylinders fit this category because they are discrete containers that are handled and transported as separate items, not as a single large-volume bulk shipment. They’re designed for smaller quantities and require the same hazmat packaging standards (such as compatibility, labeling, and leak protection) but do not constitute bulk packaging like large tanks or freight containers. This is why bags, drums, and cylinders are classified as nonbulk—it's about the size and handling of the unit, not the fact that the container itself is a primary container.
