What kind of events does LOPA typically analyze?

Layer of Protection Analysis (LOPA) is primarily focused on analyzing failure events. This method evaluates potential scenarios where a system could fail and what consequences would arise from such failures. By identifying these failure events, LOPA aims to determine the adequacy of existing layers of protection and whether additional measures are necessary to mitigate risk.

The approach involves recognizing hazardous scenarios, defining the severity of potential consequences, and assessing the likelihood of these events occurring. This way, organizations can implement necessary safeguards to protect systems and people from the outcomes of failure events.

While other types of events may be relevant in broader risk assessments, the core focus of LOPA is on understanding failures to improve safety systems effectively.
