Where must connections to ASME containers installed underground be located?

Connections to ASME containers installed underground must be located in a substantial dome, housing, or manhole to ensure proper access and safety. This design allows for controlled access to the connections, protecting them from external elements and potential damage. The substantial nature of the dome or housing provides structural integrity, ensuring that personnel can safely work on or inspect the connections without compromising their safety. Furthermore, such enclosures help prevent unauthorized access, which is important for maintaining safety standards related to propane storage and dispensing. By having the connections in these designated areas, the risks associated with leaks, exposure to weather, or physical damage can be significantly minimized, promoting a safer environment for operation and maintenance.
