Last autumn we worked with a metal fabrication shop near Cheongju that kept eight years of incident binders in a locked cabinet next to the first-aid station. No one wanted to delay the chart briefing until a scanning project finished.
We index binders by month and incident type before any photography. Each page receives a temporary reference sticker that appears in our working spreadsheet and later on the chart footnotes.
Lighting matters more than camera resolution. We use diffused lamps to avoid glare on carbon-copy forms. Faded entries get a transcription note rather than a guess.
Chart panels built from paper sources include a small inset showing the binder tab colour and shelf location. When an executive asks for detail, the EHS manager walks to the same binder in minutes.
This method is slower than API imports and that is acceptable. The goal is a trustworthy atlas for the board, not a live feed. Plants often digitise after they see which fields were missing from older pages.
