Fire Extinguisher Inspection Tracker

Three stacked layers under NFPA 10-style rules: MONTHLY visual checks (pressure gauge in range, pin and seal intact, accessible, no damage — 30 seconds anyone can do), ANNUAL maintenance by a qualified service company (tagged), and the long-cycle internals — dry chemical types commonly need 6-year internal examination and 12-year hydrostatic testing. Insurance inspections and fire marshals check the tags; hangars fail on the monthly layer most and the hydro layer most expensively. The board holds all three clocks per unit.

The discipline scales down better than the alternative: one out-of-cal torque value, one lost tool's grounding search, or one insurance claim against an unitemised inventory each cost more than years of thirty-second entries. Small operations skip the systems because nobody requires them — then meet the requirement retroactively, at incident prices. The board is the cheap version of that lesson.

Clearing site data deletes locally stored entries — that's the price of a genuinely private, server-free design. Protect yourself with the one-click CSV download before any cleanup, OS reinstall or device change: re-importing history later beats reconstructing it from memory.

Always — the CSV export is a complete, lossless dump of your shop record, generated locally in one click. Import it into commercial software, archive it with your files, or post-process it in a spreadsheet. No lock-in is deliberate: data you can't take with you isn't really yours.
