It is whether the facility can demonstrate that fire-rated openings, access controls, alarm interfaces, and evacuation routes are being kept ready for the conditions the site has planned for.

Operators need to understand which source is preferred, which alternate source is available, what transfer mode is permitted, and whether the downstream load can tolerate the planned action.
