Hazard and operability studies (HAZOP studies) - Application guide

This technical specification outlines a systematic methodology for assessing risks and analyzing operational safety within complex industrial and engineering processes. It provides detailed guidance on the Hazard and Operability Study technique, widely recognized as a structured approach for identifying potential hazards and operational problems. The document establishes a framework for multidisciplinary teams to systematically examine design intentions and operational scenarios, ensuring that deviations from intended operations are detected at early stages. It defines the scope, organization, and procedure for conducting such studies, emphasizing the importance of thorough documentation and follow-up actions. The approach encourages a proactive stance in risk management by identifying causes and consequences of potential failures before they occur. It serves as a practical reference for engineers, safety officers, and management personnel involved in the design, construction, and operation of facilities. The methodology described aims to enhance process safety while maintaining operational efficiency. By adhering to the principles set forth, organizations can better manage risks associated with complex systems, contributing to overall safety performance and regulatory compliance in industrial environments.
