Cryogenic liquids cannot be shipped in intermodal containers because they are considered to be too unstable for this type of shipment.

• A. False
• B. True
• C. Not sure
• D. Not applicable

Answer: (A)

Cryogenic liquids can be shipped in intermodal containers when the container is specifically designed for cryogenic service. These shipments use insulated, vacuum‑jacketed ISO tank containers with an inner vessel and a venting system to manage boil-off gas. The extreme cold isn’t about instability of the liquid itself; it’s about keeping it cold and safely handling the pressure from vaporization. Proper cryogenic containers meet hazmat packaging requirements and are equipped with relief devices to prevent overpressure. So saying they cannot be shipped intermodal because they’re too unstable isn’t correct—the right, engineered containers make this a routine practice for liquids like LN2, LOX, or LNG.
