Which organization developed the LOPA methodology?

The Layer of Protection Analysis (LOPA) methodology was developed by the Center for Chemical Process Safety (CCPS). This organization focuses on fostering a better understanding of safety in chemical processes through guidelines, tools, education, and training. LOPA is a quantitative risk assessment tool that helps organizations evaluate the adequacy of their risk mitigations by examining layers of protection in place against potential hazards.

The CCPS contributed significantly to the development of LOPA as part of their initiative to enhance process safety within the chemical industry. Their expertise in chemical processes and risk management is encapsulated in various publications and resources aimed at helping professionals implement effective safety measures.

Other organizations listed may address safety and risk management in other contexts, but the specific origin and methodology of LOPA can be directly attributed to the work conducted by the CCPS.
