Scope- and findings-based preventive-maintenance checklist
A structure for walkthroughs, technical visits and triggers without turning external frequencies into local obligations.

In this article
A useful checklist confirms what was observed, who performed it and the next step. It should not combine operator tasks, specialized testing and authority decisions in one undifferentiated list.
Control data
- Station, date, shift and responsible person.
- Unambiguous equipment or component identification.
- Normal condition, finding, inaccessible or not applicable.
- Photograph or reading when relevant.
- Action, priority, owner and closeout date.
Operational walkthrough
Observe active alarms, visible damage, odors or product, water, lids, hoses, nozzles, breakaways, spill buckets, sumps, drains, signage and housekeeping. Personnel should not open or intervene in equipment without authorization.
Technical visit
The technician’s list follows the installed equipment and work order. It may include functional tests, connections, filters, metering, monitoring or safety, always according to the applicable manual and procedure.
Triggers
An alarm, suspected leak, impact, altered seal, measurement discrepancy, water, flooding or recent repair may prompt an earlier review. The program should respond to condition instead of blindly waiting for the next date.
Frequencies
Assign every interval to its source: current requirement, manufacturer, certificate, history or approved technical criterion. If evidence is insufficient, mark the frequency as pending confirmation. The maintenance path helps separate preparation, observation, escalation and closeout.
To record assets, findings, evidence, owners and closeout, use the printable maintenance tracking sheet. It is a working aid, not an official form.
Sources for adapting the checklist
PEI RP900 (2021 edition, English) publishes practices and inspection checklists for underground storage systems. The EPA practical guide provides operation and maintenance checklists and records while summarizing U.S. federal requirements. These are references for comparing methods, not an official Panama checklist or automatically applicable inspection intervals. Match each item to the installed equipment, manufacturer instructions and requirements currently in force.
