For how long must logs related to the operation of the plant be kept?

In many jurisdictions, regulations often stipulate that operational logs and records related to the functioning and maintenance of a plant should be retained for a period of 7 years. This timeframe allows for sufficient time to review operational history, ensure compliance with safety standards, and provide documentation in the event of audits or investigations. Retaining these logs for 7 years strikes a balance between legal requirements and the practicalities of storage and management of records. Keeping records longer than necessary may lead to unnecessary clutter, while not retaining them long enough could result in a lack of important historical data when needed.
