Why is it essential to perform LOPA on a regular basis?

Performing Layer of Protection Analysis (LOPA) on a regular basis is crucial to identify new risks or changes in existing risks over time. As systems and processes evolve, factors such as changes in operations, technology, personnel, or external conditions can introduce new hazards or alter the risk profile of existing ones. Regular LOPA assessments help organizations to stay proactive in managing risks, ensuring that all potential vulnerabilities are considered, and that appropriate protective layers are put in place or modified as needed.

This ongoing evaluation supports continuous improvement in safety and risk management practices, which is essential for maintaining safety standards and preventing incidents. By regularly re-assessing risks, organizations can adapt to dynamic environments and emerging threats, thereby enhancing their overall safety culture and risk mitigation strategies.
