Periodic review – opportunity or chore?
Good practice calls for a periodic review of major hazard safety cases to ensure that the 'case for safety' remains valid. Indeed, many regulatory regimes and corporate standards have a requirement for 'periodic' or 'thorough' review, and provide guidance on the frequency and content of the review. At first sight, the potentially wide ranging nature of periodic reviews can appear daunting and onerous, with the potential to place a heavy burden on resources. But a well managed periodic review provides a great opportunity to strengthen the connection between the safety case and the real world.
