What is the purpose of maintaining operation and maintenance logs?

• A. For traceability, regulatory compliance, corrective actions, and continuous improvement.
• B. To decorate the lab.
• C. To store unused chemicals.
• D. To replace staff training.

Answer: (A)

Maintaining operation and maintenance logs provides a clear record of what was done, when, and by whom, creating a traceable history of equipment and process actions. This supports regulatory compliance by ensuring there are documented inspections, repairs, and maintenance activities available for audits. It also helps identify recurring issues and drive corrective actions, while the collected data can be analyzed to improve maintenance scheduling and procedures over time. A well-kept log typically notes the date, equipment, tasks performed, parts used, readings, and any observations or deviations. This purpose isn’t for decoration, storing unused chemicals, or replacing training, though training events can be documented within the logs as part of overall records.
