Layer of Protection Analysis (LOPA) is a risk management technique used to assess and control industrial hazards. It identifies potential risks and analyzes "layers" of safety measures, like alarms and interlocks that could prevent incidents. By assigning each layer a probability of failure, LOPA calculates the likelihood of an event and compares it to acceptable risk levels. This helps industries, especially chemical and oil and gas, determine if additional safeguards are needed for safety compliance. If you want to know more about it, then watch this video.
