Which of the following sets of PSM elements most commonly interact with operational changes?

The option that includes operating procedures and management review is correct because both elements are integral to ensuring that operational changes are properly managed within a Process Safety Management (PSM) system.

Operating procedures provide detailed instructions on how to carry out processes safely and effectively. When there are operational changes—such as modifications to equipment, shifts in process conditions, or the introduction of new materials—these procedures must be reviewed and updated to reflect the changes. This ensures that all personnel involved have the most current and relevant guidelines to follow, thereby minimizing the risk of incidents caused by outdated or ineffective procedures.

Management review is equally important, as it involves the oversight and evaluation of the PSM elements to ensure they are functioning properly and meeting safety objectives. Changes in operations can introduce new hazards or alter existing safety conditions that require a managerial response or policy adjustments. Through management review, organizations are able to assess the potential impacts of operational changes, allocate necessary resources, and implement any required amendments to enhance safety practices.

In contrast, the other options either focus on elements that do not interact as directly with operational changes or combine elements that, while important, do not specifically address the immediate relationship between procedures and management oversight in the context of changes in operations.
