Mobile containers designed to transport propane under the specifications of the Department of Transportation (DOT) and the American Society of Mechanical Engineers (ASME) must be equipped with a full internal pressure relief valve or a flush-type valve. The purpose of these valves is to ensure safety by preventing excessive pressure buildup within the container. A full internal pressure relief valve can relieve pressure without venting propane to the atmosphere, thereby enhancing safety during transport.

Furthermore, these valves are crucial in protecting both the container and the environment from the dangers associated with propane under high pressure. A flush-type valve, which is designed to be flush with the container surface, minimizes the risk of accidental damage or inadvertent operation, making it suitable for mobile applications.

While pressure relief valves and internal pressure relief valves are important components for safety, the designation of "full internal pressure relief valve or flush-type" specifically meets the regulatory requirements and safety standards necessary for the design and operation of DOT and ASME mobile containers. Thus, this choice clearly aligns with the established safety protocols and engineering practices required in propane transport.
