Start with oxygen monitor slips, fan settings and shift handoff notes. It is the source used to decide whether one wall reading describes conditions at each occupied work station; it is not the decision itself. The rule only works if the source describes conditions at the north furnace aisle at Cinder Works.
Known: the current file counts 51 readings with a fan setting and worker location attached, compared with 49 in the prior window. Anew work docket opens with a named machine, shift and measure. The entries have dates and a named clerk.
Disputed: Managers prefer a single stable monitor. Crew representatives want a location note when the fan setting changes. One side emphasizes the posted total; the other points to the wall monitor remains active during the ten-minute handoff.
Why it matters: the decision determines which residents can rely on the service and which staff must carry out the change. The file does not settle that by itself.
Next: The Year first, cinder winter window 3 file remains open for its scheduled decision. The next review will compare the wall monitor with two hand-held readings.
