Under what circumstances are safety accessories (safety valves, rupture disks, etc.) installed?

Appendix B of GB150.1 states only that when overpressure may occur during the operation of the vessel, it shall be equipped as required. . . . Does that mean it’s sufficient to equip them with safety valves and other accessories, without regard to factors such as the category of the pressure vessel or the medium used in its operation? Is it set only in situations where overpressure is possible? How do you guys set it up in practice?
Devices that are not subject to overpressure do not require safety valves, but it is necessary to take into account all possible scenarios of overpressure.
Whenever overpressure can be caused by divine or demonic forces, a safety valve must be installed
It has nothing to do with whether it’s used or not; it’s the type of medium that matters.
Reactor vessels that require pressure increase are generally needed, as are storage vessels such as liquefied gas tanks in which pressure rises due to temperature effects.
It is related to the medium used in operating pressure vessels; for example, liquefied gases are affected by the ambient temperature... There are many, many situations in which overpressure can occur...
This is also a situation in which overpressure may occur.
The pressure comes from the outside and can be reliably controlled; it is not necessary to install a safety relief device on the body

For example, if a safety valve is installed on the gas supply pipeline, does it mean that no safety valve is needed on the container?
