Niri Flint opens fan settings, air readings and the branch occupancy map at the North Fan chamber. Before anyone changes a mark, the crew checks the fan is lowered during a stone inspection near one return shaft. The first seep period sets the pace of the work.
The page holds 78 readings with a fan setting and occupied branch attached. Niri Flint reads the preceding count, 77, before the next line is entered. A number without a date would not tell the next crew what changed.
The maintenance office posts a single average. Residents ask for the reading at the occupied branch during the change. Here the difference is visible between the posted rule and the route, service or shift just beyond the door.
Residents and route crews submit corrections before the public table closes. The Year second, first seep window 1 file remains open for its scheduled decision. The fan board will pair each reading with its setting and branch name.
The shift closes with the source page attached to the board. The next file uses a new date and scope.
