What is the acceptable pressure range for IM-101 intermodal containers (IMO Type 1)?

• A. 25.4 - 100 PSI
• B. 14.7 - 25.4 PSI
• C. 100 - 600 PSI
• D. Cryogenic

Answer: (A)

IM-101 intermodal containers are designed for low-pressure service and have a defined safe working range expressed by their maximum allowable working pressure. For these tanks, the interior pressure during normal operation should stay above about 25 psi but must not exceed 100 psi. This range comes from the tank’s design and certification: it’s built to handle up to 100 psi and not intended to operate near atmospheric pressure alone or at much higher pressures. The other options don’t fit because one is essentially atmospheric or too low, another suggests pressures well above what IM-101 is rated for, and the last is about temperature class (cryogenic) rather than a pressure range.
