The vast majority of safety accidents in university laboratories occur when instructors, students, or researchers perform experimental procedures. Process safety management (PSM) has become a weak link in the laboratory safety governance system of higher education institutions, and no systematic and effective management paradigm has yet been established. This paper adopts a comparative research method based on investigation and survey. On the basis of systematically sorting out the framework and core elements of the PSM system used in industry, this study conducts an in-depth investigation into the practical exploration and existing problems of PSM in domestic university laboratories. Combined with the characteristics of teaching and research activities in university laboratories, a dynamic process safety management (DPSM) model for university laboratories is developed. This model takes hazard identification as the starting point, risk assessment, grading and classification as the core, targeted control measures as the main body, and emergency response and personal protection as the bottom-line safeguards. Preliminary application practices have also been carried out. The results show that the DPSM model effectively reduces inherent laboratory risks, improves the level of refinement and dynamism in process safety control, and provides theoretical references and practical approaches for improving and implementing laboratory safety management systems in higher education institutions.

This paper adopts an analytical comparison method. First, it systematically investigates mature PSM systems used in industry, as well as the preliminary research and exploratory achievements of universities in planning laboratory process safety management systems. Second, it compares and analyzes these practical experiences, examining the similarities and differences among the 20 elements of industrial chemical PSM in domestic and international practice. It also systematically analyzes the characteristics, advantages, and disadvantages of the RAMP risk prevention and control system developed by domestic and foreign universities, as well as scientific and technological societies.

In terms of inherent safety, this paper systematically plans all system elements related to hazard identification, risk assessment, and risk control in laboratory process management, establishes a DPSM system for university laboratories, and demonstrates its implementation methods and pathways through practical applications.

DPSM is a dynamic management system based on risk identification and assessment. Through the scientific identification of all hazard sources in university laboratories, it evaluates hazards using appropriate assessment methods and technical approaches, and formulates targeted control measures and emergency disposal procedures based on the assessment results. This paper also systematically expounds the relationships among process management elements, such as hazard identification, risk assessment, the establishment of control measures, and emergency disposal. The elements of the PSM system form an organic whole, in which hazard identification is the foundation of process management, and risk assessment is the core. To cultivate high-level talent, universities can establish laboratory PSM systems suited to their characteristics by adopting advanced concepts and practical experience from enterprise PSM. This approach not only improves the laboratory safety management model but also prepares high-quality professionals with strong safety literacy for employment in enterprises. Meanwhile, transforming the laboratory safety hazard management model toward pre-event prevention, while strengthening the identification and assessment of safety risks and the targeted rectification of key safety risks at the source, will continuously improve laboratory safety risk control capabilities, fundamentally preventing and eliminating potential safety accidents.
