Finally, the correlation analysis was used to verify the model. The comparative analysis results showed that the linear correlation of the experimental group and the control group was 0.916, and the two groups of values and fluctuation trends were consistent, indicating the reliability of the assessment model.

The 1227/SiO<sub>2</sub>/CNF foam system could completely extinguish the flame within 30 s in the small-scale fire extinguishing test, which demonstrated the same extinguishing efficiency with aqueous film-forming foam extinguishing agent (AFFF).

Despite its versatility and sustainability, hydrogen presents notable safety concerns due to its flammability, ignitability, and tendency to leak and embrittle metallic materials. To ensure the reliability of hydrogen technologies, regular inspection activities are essential. However, standards for designing, operating, and inspecting these components are still under development. Additionally, the complexity of the human-machine couplings involved can compromise the success of an inspection. In this context, this study proposes an innovative methodology to evaluate how human, technical, and environmental factors impact the workability of hydrogen inspections operations. The methodology combines the System-Theoretic Accident Model and Processes (STAMP) and Bayesian Networks to assess the complexity of human performance during acoustic emission testing of hydrogen storage tanks. Unlike traditional sequential methods, this approach employs STAMP to structure a Bayesian Network, enabling a comprehensive understanding of operator-process interactions. Prior probabilities, derived from Human Reliability Analysis, are incorporated into the Bayesian Network, facilitating quantitative assessments of inspection success probabilities. The study reveals that tasks may become unsafe under conditions that adversely affect the quality of the inspection. Furthermore, the operating environment, experience of operators, and their safety attitudes are critical for successful inspections. The adaptability of this methodology makes it a valuable tool for assessing human performance in their operations within complex socio-technical systems and safety-critical applications.</div></div>","PeriodicalId":16291,"journal":{"name":"Journal of Loss Prevention in The Process Industries","volume":"97 ","pages":"Article 105687"},"PeriodicalIF":3.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144185631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the experimental data obtained by thermocouples and MATLAB image processing, the effects of sample width and surface slope on equivalent burning diameter, fire spread rate and flame height were analysed. The results shows that the fire spreading process of PMMA dust layer formed a zone similar to an oil pool fire, which advanced continuously with the flame front.
