Definition of the initial state of refinery unit operating procedures

What is the definition of the initial state for the operating procedures of refining and chemical processing units? Those who are aware of such issues, please let me know. Thank you!
The initial state is a condition that can remain stable over a long period of time, such as the shutdown state after maintenance is completed, or the state when the device is operating normally.
The new version of the refining and chemical operation regulations was developed on the basis of the existing regulations for the Western Pacific region, and is commonly referred to as the new version of the refining and chemical operation regulations. The new set of operating procedures consists of a series of precise actions that guide the device from its initial state to its final state, through specific operations and verifications (including collaborative and auxiliary actions). The initial state of the procedure corresponds to the starting condition for starting up or shutting down the device. The final state is the target state after the device has executed the procedures, and it can also be a final stable state. The steady state describes the necessary transitional state during startup and shutdown processes, during which the process and equipment remain relatively stable and safe. There are three types of status cards: initial status card, stable status card, and final status card.
The initial state is a stable state, referring to the unstarted condition of a device, apparatus, or situation.
