Ketta Ash is the ventilation board reader. On this cinder winter visit, the work begins with a dated entry and ends with a second check from someone who did not make the first one.

The fan-hour totals, temperature notes and the neighborhood air board lists 23 fan hours recorded with a matching air sample; the previous window lists 27. Nazza Wire checked both against public notices checked against the copies households actually received. The number is one part of a larger handoff between the office, the people who use the service and the staff expected to maintain it.

The plant totals are posted monthly. Nearby households want the maintenance hours listed on the same board. Residents and workers have asked the clerk to keep their accounts beside the source count rather than turn them into a single average.

Anew work docket opens with a named machine, shift and measure. The Year first, cinder winter window 3 file remains open for its scheduled decision. The vent office will add maintenance intervals to each public reading.
