Which statement correctly identifies Cryogenic Intermodal shipments?

• A. 100-500 psi and -40°F
• B. 25.4-100 psi and 0°F
• C. 14.5-25.4 psi and -80°F
• D. 23.5+ psi and -130°F or lower

Answer: (D)

Cryogenic intermodal shipments involve keeping contents at extremely low temperatures so that liquefied gases remain in liquid form during transit. The defining cold is around -130°F or lower, which is why this option best matches the typical cryogenic freight profile. The accompanying pressure value of about 23.5 psi or a similar low, controlled rating reflects the containment requirements for cryogenic vessels used in intermodal transport, where the vessel is designed to handle very cold temperatures with a modest pressure range. The other choices pair temperatures that are not cryogenic with pressure ranges that don’t align with how cryogenic containers are designed to operate, so they don’t fit as accurately.
