What are the two categories of containers for hazardous materials?

• A. Plastic and metal.
• B. Small and large.
• C. Bulk and nonbulk containers.
• D. Pressurized and unpressurized.

Answer: (C)

Hazardous-material containers are categorized by capacity and how they’re used for transport: bulk containers and nonbulk containers. Bulk containers are large-capacity vessels designed to move significant quantities of hazmat, such as tanker trailers, rail tank cars, and large intermodal tanks. Nonbulk containers cover smaller packages intended for individual shipments, like drums, jerricans, boxes, and gas cylinders. This bulk versus nonbulk distinction matters because it guides the applicable packaging standards, labeling, and handling requirements—the regulations differ based on the amount and the way the material is transported. The other options don’t reflect the standard regulatory distinction: material type (plastic vs metal), arbitrary size labels (small vs large), or pressure state (pressurized vs unpressurized) aren’t the formal categories used to classify hazmat containers.
