Which container type is round, horseshoe-shaped and may be insulated, used for hazardous liquids?

• A. Dry Bulk Cargo Tank
• B. Type A
• C. DOT 407
• D. Type B

Answer: (C)

Hazardous liquid tanks are defined by standardized shapes and construction, which helps handlers know how they’re built to handle pressure, temperature, and loading. A tank that is round in cross-section, with a horseshoe-like shape and the possibility of insulation, matches the DOT 407 cargo tank. This type is a low‑pressure, non‑pressurized tanker designed specifically for flammable liquids, and insulation is used when temperature control is needed for the product. The other options describe different concepts: a dry bulk cargo tank carries dry powders or granules, not liquids; Type A and Type B refer to packaging classifications focused on strength requirements rather than a particular tank shape, with Type B designed for higher hazard or larger quantities and different construction. So the container described best fits the DOT 407 low‑pressure liquid tanker.
