Process safety is an academic discipline and applied methodology concerned with the prevention of catastrophic incidents arising from the uncontrolled release of hazardous materials or energy within industrial processes. It systematically investigates the identification, analysis, and mitigation of potential hazards inherent in complex systems and operations. This field encompasses the development and implementation of robust engineering design principles, operational procedures, management systems, and organizational culture to ensure the integrity and reliability of process facilities. Its significance lies in minimizing the risk of major accidents, thereby safeguarding human life, environmental health, and economic stability.
