HAZOP analysis is a systematic, team-based qualitative risk analysis method used to identify potential risks and issues in engineering and process systems. (1) The steps of a HAZOP analysis typically include: defining objectives and scope, selecting a team, describing the process, identifying nodes, choosing guiding words, analyzing deviations, determining causes and consequences, assessing risks, recommending improvement measures, and documenting and reporting. (2) The HAZOP analysis process begins with definition and preparation, followed by meetings for the actual analysis, and finally by the compilation of results and the preparation of a report. (3) The experience-based HAZOP analysis method is applicable to experienced teams familiar with the processes and operations, and is suitable for complex or novel systems. The key to HAZOP analysis during the design phase is to understand the design intent, identify potential deviations, and analyze their causes and consequences to ensure design safety. A detailed plan must be developed for HAZOP analysis during the operation phase to ensure proper organization and management of the team; key success factors include continuous monitoring and regular updates. The practical rules of HAZOP include node segmentation, deviation analysis, root cause identification, consequence analysis, and evaluation of control measures. The analysis of existing safety measures involves a review of instrument settings, alarm systems, interlock systems, and other safety devices. The quality of the HAZOP analysis results needs to be reviewed and verified by experienced experts. LOPA is an advanced risk analysis method used to evaluate and determine independent protection layers and Safety Integrity Levels (SIL). The definition of SIL includes methods such as the matrix approach, risk mapping, and protection layer analysis, aiming to classify safety requirements based on risk levels. SIL verification methods include determining the failure probability of individual components (PFD) and calculating the PFD of the entire safety instrumented system (SIF loop), etc. .
