Records retention: What is the requirement for logbooks vs SOPs?

• A. Logbooks: 5 years; SOPs: 5 years after retirement
• B. All records: indefinitely
• C. All records: 1 year
• D. All records: 3 years

Answer: (A)

Retention of records is about keeping the right documents long enough to support audits, investigations, and future reference. Logbooks capture day-to-day activities, steps taken, observations, and any deviations as they happened, so they should be kept for five years to ensure that the details needed to understand what was done are available if questions arise later. SOPs document the approved procedures that ensure consistency and regulatory compliance across work processes. Keeping SOPs for five years after retirement ensures that, even when a process or personnel is no longer active, the established methods remain accessible for review, training, or verification of how tasks were intended to be performed.

Other options don’t fit because they either push all records to one uniform period or propose too short or indeterminate retention. The split—five years for logbooks and five years after retirement for SOPs—reflects the practical need to preserve day-to-day records and the governing procedures for a meaningful window of time.
