What is the purpose of the Clark and O'Brien method?

The Clark and O'Brien method is specifically designed to conduct quantitative risk assessments for explosion hazards. This methodology provides a systematic approach to identifying potential explosion risks associated with various processes in chemical engineering and other industries handling hazardous materials. By quantifying the likelihood and potential consequences of explosion events, the method helps organizations to develop strategies for mitigating risks and enhancing safety protocols. This quantitative assessment is crucial for ensuring that sufficient safety measures are in place, thereby protecting both personnel and facility infrastructure from the dangers associated with explosive atmospheres.

The method's focus on quantitative analysis differentiates it from approaches that might assess worker performance or safety in a more general sense, or evaluate chemical compatibility without direct application to explosion risk.
