Layer of Protection Analysis (LOPA)

Layer of Protection Analysis (LOPA) is a systematic risk assessment method used in industries to evaluate the likelihood and severity of potential hazards. It identifies hazards, analyzes existing safeguards, and determines if additional protective measures are needed. LOPA helps ensure safety by quantifying risks and confirming that multiple safety barriers are in place to prevent accidents or mitigate their consequences. It provides a structured approach to prioritize safety improvements, balancing cost and effectiveness, to protect people, the environment, and assets.
