Container 31 describes which feature?

• A. High pressure (rounded ends)
• B. Cryogenic (rear control housing)
• C. Oval egg
• D. V or W shaped

Answer: (A)

Rounded ends on a cylindrical container indicate a high‑pressure gas cylinder. The hemispherical or rounded ends are designed to evenly distribute stress from the internal gas pressure, which is a hallmark of containers used for compressed gases. That’s why container 31 is described as high pressure with rounded ends. The other options don’t fit this profile: a cryogenic tank would be a large insulated vessel with a neck and control components, not a simple rounded-ended cylinder. An oval egg or a V/W shaped container aren’t standard profiles used to denote high‑pressure cylinders in hazmat visuals.
