In the pressure vessel regulations, are all the media in the first group classified as category II or category III pressure vessels? In other words, as long as a medium is classified in the first group, it is either a Class 2 or a Class 3 pressure vessel; it cannot be a Class 1 pressure vessel
Yes, all the media in the first group specified in the regulations fall under category II or category III pressure vessels, and do not include category I pressure vessels. .
You’re roughly correct; it could also be an external device.
It should be; there are no Class I containers in the diagram
There is no type of container in the first group of media.
