HAZOP analysis

HAZOP analysis, also known as hazard and operability analysis. According to scientific procedures and methods, a team of relevant experts identifies, analyzes, and evaluates potential hazards in engineering projects or production equipment from a systematic perspective, identifies production equipment design, operation, and maintenance procedures, and proposes improvement suggestions and recommendations to enhance the safety and operability of the production process.

Overview of HAZOP AnalysisHAZOP(Hazard and Operability Analysis), Hazard and Operability Analysis.

The HAZOP analysis method is a scientific procedure and method that identifies, analyzes, and evaluates potential hazards in engineering projects or production equipment from a systematic perspective. It identifies the design, operation, and maintenance procedures of production equipment, and proposes improvement suggestions and recommendations to enhance the safety and operability of the equipment process, providing a basis for decision-making on basic disaster prevention measures and emergency plans.

The main purpose of HAZOP is to conduct a design review of the safety and operability of the equipment HAZOP analysis is jointly studied by experts in production management, process, safety, equipment, electrical, instrumentation, environmental protection, economics, and other professions; This analysis method includes identifying potential deviations from the design purpose, analyzing their possible causes, and evaluating the corresponding consequences. It uses standard guiding words, combined with relevant process parameters, etc., to conduct systematic analysis according to the process. And analyze the possible problems, causes, consequences, and measures that should be taken during normal/abnormal situations.

The HAZOP analysis method has three major characteristics:

Firstly, the viewpoint of system security has been established, rather than the viewpoint of individual device security; Secondly, it has good systematicity and completeness, which is conducive to discovering various potential dangers; Once again, it is structurally sound and easy to grasp.

Application of HAZOP analysis

HAZOP analysis is a structured hazard analysis tool suitable for inspecting operational facilities in the later stages of detailed design or analyzing changes made to existing facilities. The following provides a detailed introduction to the application of HAZOP and other analysis methods at different stages of the system lifecycle.

(1) At this stage of the system lifecycle, the concept and definition phase will determine the design concept and main components of the system, but the detailed design and documentation required for conducting HAZOP analysis have not yet been formed. However, it is necessary to identify the main hazards at this stage in order to consider them in the design process and facilitate subsequent HAZOP analysis. To conduct the above research, other basic methods should be used. For a description of these methods, please refer to IEC 60300-3-9. ）

(2) In the design and development phase of the system lifecycle, detailed design is formed, operational methods are determined, and design documents are compiled. The design tends to mature and is basically fixed. The timing for conducting HAZOP analysis is just before the design is fixed and unchanged. At this stage, the design should be detailed enough to obtain meaningful answers through HAZOP inquiry. It is crucial to establish a system for evaluating any changes made after the completion of HAZOP analysis, which should be effective throughout the entire lifecycle of the system.

(3) If there are risks during the trial operation and operation of the system during the manufacturing and installation phase, or if correct operating procedures and instructions are crucial, or if there are significant changes in the design purpose during the later stages, it is recommended to conduct a HAZOP analysis before the system is started. At this point, data materials such as trial operation and operating instructions should be available. In addition, the analysis should re-examine all issues identified during early analysis to ensure they are resolved.

(4) During the operation and maintenance phase, for changes that affect system safety, operability, or environmental impact, HAZOP analysis should be considered before the change. In addition, the system should be regularly inspected to eliminate the impact of minor daily changes. When conducting HAZOP analysis, it should be ensured that new design documents and operating instructions are used in the analysis.

(5) During the phase of discontinuation and scrapping, there may be hazards that would not occur during normal operation, so a hazard analysis may be necessary at this stage. If there are previous analysis records, the analysis of this stage can be quickly completed. Analysis records should be kept throughout the entire lifecycle of the system to ensure prompt resolution of issues that arise during the shutdown or scrapping phase.

Expert introduction of HAZOP analysis team:

Guo Junli

I graduated from China University of Petroleum in July 1996 and have been working in the chemical industry since then. I am familiar with chemical process flow, equipment, self-control, safety and other related knowledge. I have worked as an internal and external operator, shift leader, dispatcher, workshop director, and safety production supervisor at Yangmei Three Dimensional Group. Since 2011, I have been committed to promoting and applying the HAZOP method in China and have conducted a large number of practical work on HAZOP analysis projects; As an expert in the field of safety, I have served as a technical expert in the accident investigation team of the State Administration of Work Safety, investigating the Guangwei explosion accident.

As an expert in the field of HAZOP, I have been invited multiple times by the China Chemical Safety Association to serve as a keynote speaker in HAZOP training courses. I have organized and participated in numerous HAZOP training sessions, accumulating rich experience in the application and teaching of HAZOP methods. As the former chairman of HAZOP, I have led the analysis of over 100 sets of chemical plants in the fields of petrochemical, coal chemical, pharmaceutical chemical, fluorine chemical, pesticide chemical, etc. I am a practical representative in the field of HAZOP in China.
