Despite the promise of wearable exoskeletons for mitigating strain, limited on-site comparative research exists, particularly across distinct designs. This study addresses that gap by evaluating two back-support exoskeletons, HAPO Back (rigid) and BISKO (soft textile-based), in realistic masonry tasks. Fifteen masons from five sites tested both exoskeletons over two days through structured interviews, yielding noticeable strain reductions relative to baseline conditions. BISKO reduced perceived fatigue by 50.53% and perceived exertion by 32.57%, outperforming HAPO’s 27.39% and 14.76% reductions, respectively. BISKO also excelled in comfort (35.94% better) and adjustability (49.11% better), resulting in significantly less movement hindrance. Contrasting acceptance patterns emerged: HAPO users reported a 158% drop in continued-use willingness, whereas BISKO showed only an 8.52% decline. Correlation analysis highlighted movement hindrance (r = 0.79) and adjustability (r = 0.76) as stronger predictors of ongoing use than physical benefits alone. These findings underscore the importance of lightweight, worker-friendly designs that integrate well with dynamic construction tasks. This research challenges conventional exoskeleton development that focuses primarily on mechanical load reduction. The field-based approach provides insights under actual working conditions, offering practical guidelines for future product development and adoption strategies. Ultimately, prioritizing comfort and usability emerges as a decisive factor for sustained exoskeleton usage, reinforcing the critical role of human-centered designs for construction ergonomics. Such emphasis is especially crucial for masons, whose tasks involve varied postures and material handling. Future studies should expand these comparisons to other trades to refine exoskeleton design guidelines.</div></div>","PeriodicalId":21375,"journal":{"name":"Safety Science","volume":"197 ","pages":"Article 107138"},"PeriodicalIF":5.4,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146170542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, evidence on the effects of work task stress is inconsistent: some studies suggest that stress can motivate better safety performance, whereas others provide evidence that the accumulation of industry-inherent pressures and role demands undermines it. This debate underscores uncertainty about the mechanisms through which work task stress influences safety outcomes, particularly the role of cognitive appraisals. Building on cognitive appraisal theory and the job demands-resources (JD-R) model, we propose a dual-pathway mediation model in which work task stress influences safety compliance and safety participation through two competing appraisal processes. A field survey of 308 frontline employees in high-risk industries reveals that work task stress exhibits double-edged effects: it improves both safety compliance and safety participation through challenge appraisals while simultaneously diminishing them through hindrance appraisals. Moreover, vocational identity significantly attenuates the hindrance pathway but does not reliably enhance the positive effects of challenge appraisals. This research challenges the traditional either-or assumption of stress appraisals by adopting a dual-pathway framework, which offers a new lens for explaining the mechanisms linking stress to safety performance in safety critical contexts. Simultaneously, the asymmetric moderating effect of vocational identity enriches theoretical understanding of the distinct functions of personal resources in the JD-R model.</div></div>","PeriodicalId":21375,"journal":{"name":"Safety Science","volume":"197 ","pages":"Article 107120"},"PeriodicalIF":5.4,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146025416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the lack of comprehensive methods for this purpose, this article presents a model to estimate the time to complete SAR missions in the Canadian Arctic using helicopter assets. Designed as a Discrete Event Simulation (DES) model and based on an extensive consultation process, the model accounts for key factors such as incident locations, helicopter routes, refueling needs, and the number of people in distress. An essential component concerns the assessment of the SAR helicopter’s operability under various environmental conditions. With the SAR helicopter DES model embedded in a Monte Carlo simulation framework, and using statistics derived from environmental data, probabilistic estimates of rescue times are obtained for various plausible maritime incidents, illustrating the applicability of the model. The results indicate that SAR response times are highly variable for different locations and seasons, with SAR mission times exceeding 24 h not uncommon. Whereas the model should be further validated and can be refined and extended, it sets a basis for enabling a comprehensive strategic assessment of the performance of aeronautical SAR systems.</div></div>","PeriodicalId":21375,"journal":{"name":"Safety Science","volume":"197 ","pages":"Article 107113"},"PeriodicalIF":5.4,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146025494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although knowledge graphs (KGs) offer a promising approach to structured representation and reasoning in smart construction safety management (SCSM), existing reviews fall short in analyzing KG-specific attributes, methodologies, and future-oriented implementation pathways. To address these gaps, this study systematically reviews 70 articles using a mixed-methods approach that integrates bibliometric and thematic analysis. Key findings include: (1) SCSM-specific KGs remain limited in scale, largely due to domain-specific constraints; (2) they primarily draw on safety regulations, accident reports, project data, and BIM; and (3) KG construction remains semi-automated, with high-level concept extraction still reliant on expert input. KGs are found to support four main applications: accident analysis, hazard identification, decision support, and safety knowledge management. Methodologically, KGs integrate with technologies such as BIM, digital twins, natural language processing, and computer vision to enhance safety performance analysis and decision-making. Nevertheless, challenges in automation, data integration, dynamic risk inference, and generalizability persist. This review contributes a synthesized analysis of KG traits and their alignment with SCSM needs, highlights research gaps in scalability and technology integration, and suggests future pathways combining advanced AI with novel KG paradigms.

Then, a discrete choice model was used to analyze the effects of various social, individual and environmental factors on the participants’ exit choices. The results showed that participants were not only influenced by the factors significant in individual decision-making, such as distance to exits, familiarity with exits, and smoke, but also by the choices of other group members, demonstrating a strong social influence. Additionally, the impact of smoke was more pronounced in subgroup settings.
