In this study, the pyrolysis process of biomass with high density polyethylene (HDPE) is examined with a Thermogravimetric analyzer (TG) and a tubular furnace experiment system. The co-pyrolysis products are analyzed and the synergistic effect of co-pyrolysis identified using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The results show that the synergistic effect is the strongest at the HDPE mixing ratio of 70%. Co-pyrolysis makes little difference to solid production, but it can inhibit tar production and facilitate gas production. With the increase of HDPE mixing ratio, the solid yield reduces from 24.33% to 1.08%, the tar yield increases from 19.31% to 41.60% and the gas yield first increases then reduces. Correspondingly, the relative contents of CO and CO₂ reduce from 31.48% and 26.41% to 4.16% and 3.05%, the relative content of CH₄ increases from 12.95% to 59.64% and that of H₂ content first reduces from 29.16% to 14.70% then increases from 14.70% to 33.16%. From the difference between the experimental and calculated gas precipitations, co-pyrolysis facilitates the generation of CO and CO₂ but inhibits the generation of H₂. Our systematic analysis of co-pyrolysis products of biomass with HDPE provides theoretical reference for subsequent studies and contributes to further improving the synergistic effect of co-pyrolysis process.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"3 2","pages":"Pages 121-130"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148575903","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}

This paper systematically summarizes the innovative theories, key technologies, and practical methods proposed for high-efficiency, safe, and low-dilution mining of metal mines under complex mining conditions. Based on the proposed concept of “transforming hazards into benefits” and the complex stress conditions inherent in underground metal mining, a rock failure theory system under coupled dynamic and static loading, suitable for hard rock underground mining, has been established in terms of theory. An efficient and orderly fracturing technique for hard rock and an intelligent ground pressure monitoring and early warning system have been successfully developed, providing technical support for safe and efficient mining. Several innovative approaches are proposed and applied in practice, including continuous mining in hazardous goaf environments, integrated backfilling of caved zones using phosphate waste, and safe undersea extraction with low dilution and minimal loss. The research results not only provide a comprehensive theoretical and technical framework for the safe and efficient exploitation of metal mines under complex conditions but also point out the development direction for next-generation technologies such as intelligent unmanned mining and synergistic mineral-geothermal co-extraction. These contributions offer substantial theoretical guidance and practical value for promoting sustainable mineral resource development and advancing scientific mining.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"3 2","pages":"Pages 93-105"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148575845","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 part of the study, 70 employees from nine selected swimming pool facilities participated in a standardised written survey focusing on perceived working and health conditions. In parallel, measurements of airborne hazardous substances – particularly trichloramine (NCl₃) – as well as physical and climatic environmental conditions were conducted under real operational conditions. All measured chemical and physical exposure levels were below applicable limit or assessment values. Nevertheless, the employee survey revealed pronounced subjective stress, particularly related to noise and thermal conditions. The findings indicate that even when individual limit values are met, combined exposure situations may contribute to increased perceived stress.

This includes establishing greater clarity in how international safety principles are operationalised within national regulatory regimes and aligned with domestic requirements. A persistent source of friction lies in the interpretative ambiguity surrounding the As Low As Reasonably Achievable (ALARA) principle. This study examines the issue through the analytical lens of the UK's non-prescriptive nuclear licensing regime. Within this setting, ALARA is implemented alongside closely related national and international concepts (Best Available Techniques (BAT), Optimisation, So Far As Is Reasonably Practicable (SFAIRP), and As Low As Reasonably Practicable (ALARP)), which are frequently treated as equivalent in practice. The article presents a comparative analysis of these five near-synonyms, examining their regulatory genealogies, underlying justifications, and associated compliance expectations. Drawing on boundary theory, the analysis shows that these concepts function as boundary objects whose apparent equivalence masks divergent regulatory origins and disparate underlying rationales. The analysis demonstrates how false synonymy obscures important differences in how proportionality and reasonableness are embedded at international versus national levels, with consequences for compliance expectations and reactor safety design. Collapsing these into synonymy leaves duty holders navigating unresolved conceptual tensions within a non-prescriptive regime. Such an equivalence carries consequences for reactor safety design and, at a systems level, for the predictability and effectiveness of the licensing regime. The results emphasise the need for earlier and more structured engagement to tackle false presumptions and apparent consensus, and call for sustained international dialogue aimed at developing a verified, shared understanding of proportionality and reasonableness across regulatory contexts.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"3 2","pages":"Pages 106-120"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148575902","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}

The development of risk assessment tools, e.g., accident databases and consequence models, for quantitative risk analysis (QRA) is therefore critical for achieving a realistic understanding of explosion risks. This study presents a critical review of hydrogen risk assessment tools used in QRA, with the aim of evaluating their current state and identifying research needs for reliable risk prediction in large-scale hydrogen infrastructure. It is found that accident databases lack sufficient detail on explosion characteristics, particularly in distinguishing between deflagration and detonation events. Consequence models for confined explosions are typically derived from or validated against medium-scale experiments with significant variability, while open atmospheric models rely on a limited experimental basis. In addition, many models are based on assumptions originating from hydrocarbon gas explosions or solid explosives, raising concerns regarding their applicability to hydrogen. The results indicate that improved accident reporting is required to develop reliable frequency data, and that consequence models must be further developed and validated through large-scale, hydrogen-specific experimental campaigns. Addressing these gaps is essential for enabling more accurate QRAs and a realistic assessment of explosion risks in large-scale hydrogen infrastructure.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"3 2","pages":"Pages 166-177"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148575904","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}

The stress-strain relationship and energy dissipation characteristics of anchored coal were elucidated, and the dynamic anti-impact mechanism of anchored coal was revealed. According to the analysis results, with the rising of the pre-tightening force, the peak strength of the sample reached up to 40.9 MPa. In cases where the incident energy is basically the same, the reflection energy decreases significantly with rising preload, and the increase of transmission energy is greater than that of dissipation energy. The plastic strain is gradually generated on the impact side of the anchorage sample, and the crack gradually expands to the side of the transmission rod. Under a small preload, the “X” shaped symmetrical crack is generated in the anchorage attachment of the anchoring coal body. When the preload is applied to 2.3 kN, the tensile crack gradually dominates. The larger the preload is, the more the tensile crack position deviates from the center of the bolt axis. Under the continuous compression of the wave front, the prestressed zone in the middle of the coal body is greatly compressed, and a stress rising zone is formed away from the impact side. The stress redistribution eventually leads to the damage to the anchorage interface. When the pre-tightening force of the bolt is large, the central anchorage zone can still maintain a certain anchorage performance and impact toughness, showing obvious ductile failure characteristics and higher energy dissipation capacity. The research results provide a certain experimental basis for elucidating the regulation of stress wave energy distribution and crack propagation path.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"3 1","pages":"Pages 12-22"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147757116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A questionnaire survey was conducted among 336 miners across four ASM sites in Ghana, and the data were analysed through descriptive and inferential statistics. Through factor analysis, it was observed that the 18 specific hazards across ASM sites can be grouped into seven major hazards with different levels of exposure. Repeated one-way ANOVA revealed that the hazards consisted of those with high exposure (biological, ergonomic and chemical hazards), medium exposure (physical and mechanical hazards) and low exposure (fire and electrical hazards). Thus, exposure to the hazards was ranked from highest to lowest, in the order of biological hazards, ergonomic hazards, chemical hazards, physical hazards, mechanical hazards, fire hazards and electrical hazards. This indicates that biological and ergonomic hazards remain a priority and deserve greater focus. It was also observed that over 60% of the miners indicated that the risk of workplace exposure is undesirable/unacceptable; however, they were unwilling to leave the ASM sector, suggesting a high-risk appetite and a fatalistic mindset. Further research is warranted in this area to uncover the extent to which such fatalistic beliefs are embedded in the sector and what can be done to improve the safety awareness of artisanal small-scale miners.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"3 1","pages":"Pages 71-81"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147757119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
