Then, three experts with authority in this field were chosen, and the experts’ weights were calculated. Secondly, Bayesian networks of metal processing plants were established according to accident information. In addition, questionnaire data and the expert score after fuzzing were applied to serve as probabilistic data for Bayesian networks. Finally, a safety management model was constructed based on the sensitivity analysis in the Bayesian network. It is shown that the probability of human and management errors is the largest in a plant. Compared to other factors, the probability of occurrence of an unsafe state of material is the smallest. Human errors and the ventilation system is not activated are the two factors that have the greatest influence on the accidents.

However, the risk of hydrogen leaks is inherent, and the ignition of released flammable mixture can lead to catastrophic explosion, endangering both structures and nearby personnel. This study aims to numerically investigate the hydrogen vapor cloud explosion from offshore hydrogen production platform. The solvers published within the OpenFOAM framework are validated against two public tests involving hydrogen gas explosions within obstacles. A numerical model of the hydrogen vapor cloud explosion from a conceptual offshore hydrogen production platform is then constructed. The effect of offshore facility layout configuration on flame propagation mechanism and overpressure characteristics is analyzed. Results indicate that the presence of compressor equipment and cylindrical hydrogen storage tank leads to accelerated flame propagation and higher overpressure peaks. By reducing the cross-sectional area of the compressor equipment by 68 % perpendicular to the flame propagation direction, the maximum flame propagation speed and overpressure are reduced by 88.6 % and 94.2 %, respectively. With an appropriate layout that maintains a cross-sectional area of 0.008, the presence of compressor equipment may not exacerbate the consequences compared to scenarios without any compressor equipment. This study provides a foundational basis for the safety design of offshore hydrogen production platforms, aiming to mitigate potential hydrogen explosion hazards.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"1 4","pages":"Pages 189-201"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143274598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, many enterprises still need a comprehensive understanding of Industry 4.0 concepts and their relevance to occupational safety. To address this gap, this study proposes a maturity model (MM) for evaluating occupational safety in the context of Industry 4.0. The model was developed through a three-step process: development, application, and validation. It incorporates a framework of seven analysis groups: strategy, leadership, operations, organizational culture, people, governance, and technology. Criteria for each group were established based on current Brazilian regulatory standards (ISO 45001) and recent literature. The best-worst method (BWM) was employed to assign weights to these criteria and evaluate the model's effectiveness. Testing and validation of the model were carried out in two chemical industries in Brazil. The results indicate that the proposed model effectively aids organizations in assessing their maturity level in health and occupational safety amidst Industry 4.0 challenges. It provides valuable insights for aligning organizational strategies with best practices in occupational safety and Industry 4.0 integration.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"1 4","pages":"Pages 234-246"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143273703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As we yet to know the behavior of hydrogen in critical situations, uncertainties make these tasks prone to emerging risks. Thus, hydrogen safety falls under emerging risk studies. Conventional perspective on safety, especially regarding the flammable material, focuses on calculating the hypothetical risks of failures in system. Resilience Engineering has another perspective as it focuses on normal operations, offering new perspectives to tackle emerging risks from a new angle. Born from the heart of resilience engineering, the functional resonance analysis method (FRAM) captures sociotechnical systems’ essence in a tangible way. In this study, FRAM has been used to model a series of experiments done on hydrogen management to analyze its jet fire.

The growing demand for steel of iron ores has necessitated the utilizationof low-grade iron ores for steel production. The challenges lie in the economic extraction of lean ores and their conversion into quality agglomerates for use in iron making. The utilization of low-grade iron ores has assumed greater significance for the optimal utilization of natural resources and the sustainability of the steel industry.
