What condition would trigger tank inspection, level and leak check instead of the calendar?

Bund level switch activated, tank level falling with no draw, interstitial (double-wall) leak sensor alarm, or level below the reorder point

What evidence does tank inspection, level and leak check produce for an ISO 55001 or ISO 45001 audit?

Level reconciliation record and the bund and leak sensor log, plus the statutory internal inspection report

Tank inspection, level and leak check

Q: Can tank inspection, level and leak check move from a fixed interval to a condition-based check?

Partly: part of the task converts to a condition and part stays on the calendar. Leak and level convert to sensors; the internal inspection of the tank shell stays on the interval set by the storage regulations or the written scheme.

A bund with a float switch is checked every second. A bund checked weekly can hold a week of diesel.

What does a tank inspection, level and leak check involve?

Tank inspection, level and leak check checks: tank level, bund level, interstitial sensor status, reconciled volume against deliveries and use. Observed by level transmitter, bund level switch, interstitial leak sensor. Leak and level convert to sensors; the internal inspection of the tank shell stays on the interval set by the storage regulations or the written scheme.

asset class

Condition that replaces the interval: Bund level switch activated, tank level falling with no draw, interstitial (double-wall) leak sensor alarm, or level below the reorder point
Reading that proves it: Tank level, bund level, interstitial sensor status, reconciled volume against deliveries and use
Why the interval stays: Leak and level convert to sensors; the internal inspection of the tank shell stays on the interval set by the storage regulations or the written scheme.
Evidence an auditor accepts: Level reconciliation record and the bund and leak sensor log, plus the statutory internal inspection report
First move: Put a level switch in every bund on the list; it is the cheapest leak detector there is.
