The first file on the furnace oxygen monitoring began with oxygen monitor slips, fan settings and shift handoff notes. The city then checked the source, heard affected residents and sent a second office to repeat the count.
The current Year second, smelt run window 3 file records 76 readings with a fan setting and worker location attached; the previous window records 77. The longer sequence makes the change visible, while each count remains tied to its own dates.
A turning point was the observation that the wall monitor remains active during the ten-minute handoff. It narrowed the discussion from a general claim to a question about how the rule works at the site.
Managers prefer a single stable monitor. Crew representatives want a location note when the fan setting changes. The shared record is larger than it was at the start, although the parties still assign it different weight.
The clerk attaches the contract copy and the crew’s original handoff card. The Year second, smelt run window 3 file remains open for its scheduled decision. The next review will compare the wall monitor with two hand-held readings.
