Subsequently, a cross-sectional survey of 514 employees revealed varying degrees of current presence and implementation appetite across business units. While statistical analyses showed some differences across variables such as business units, job roles, and years of experience, the small effect sizes indicated these differences had no practical significance. The study findings demonstrate that implementing new safety principles requires contextualisation to specific organisational needs and highlight the value of participatory approaches in capturing diverse perspectives. A key conclusion is that successful implementation demands tailored strategies across different business units rather than a one-size-fits-all approach.

Using a unique real-world dataset from Railway Traffic Control Centers, that contain 410,269 controller-hour observations, we employ count model analysis to investigate the relationship between human errors with workload and automation usage. Our findings reveal that traffic controller performance (represented by human errors) has a positive relationship with workload, and an inverted U-shape relationship with automation usage. Moreover, there is a significant interaction between the level of workload and automation usage. These insights offers a nuanced understanding of how cognitive workload and automation reliance impact worker performance. Our results suggest that people make fewer mistakes when doing all of (or most of) the work manually or when monitoring the automated system that is doing all or most of the work automatically. These findings provide actionable recommendations for managers on optimizing workload and automation usage balance for safety-critical enviroments.</div></div>","PeriodicalId":21375,"journal":{"name":"Safety Science","volume":"185 ","pages":"Article 106775"},"PeriodicalIF":4.7,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143156292","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}

Upon arrival 11 min later, the first responders faced a fire that had already spread and involved the whole building. To their surprise, all residents were already accounted for outside the building. The present study analyses why the fire developed that fast, why the automatic fire alarm system did not warn the emergency response centre early and how all occupants were accounted for in such a dramatic fire scenario. It turns out that the fire most likely started in one of the all-wooden floor balconies at ground level. The originally planned 1.2 m tall balcony glazing facing a public road had been substituted by wood to ensure privacy and prevent visibility. The balcony subdivision walls had 20 cm gaps at ceiling level. Analysis confirmed that this balcony construction, i.e., all-wooden and with gaps at the top of the division wall, contributed significantly both during the early fire development as well as to the very fast vertical and horizontal fire spread over the entire building façade. Post-fire interviews revealed that a significant number of occupants were awake this night, allowing them to promptly detect the fire in the building. A close-knit relationship network, including both friends and acquaintances, was of major importance regarding door-to-door alarming unaware residents about the immediate danger. From the investigations conducted after the fire it is quite clear that under different circumstances this fire could have resulted in multiple fatalities. Though the incident may be considered a success regarding the “no loss of lives” focus in Norwegian fire safety regulations, the study revealed weaknesses in balcony construction and use of materials as well as lack of exterior automatic fire detection and mitigation of external fires. The study revealed important learning points for future prevention of possibly far worse fire incidents, as well as the importance of a close-knit relationship network in a crisis situation.</div></div>","PeriodicalId":21375,"journal":{"name":"Safety Science","volume":"185 ","pages":"Article 106782"},"PeriodicalIF":4.7,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143156297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, residents, experts and authorities all exhibit different understandings of the possibility and potential consequences of these hazards, which gives rise to ambiguity and tension as risk perceptions vary. In this study, we have interviewed residents, authorities and experts in four different locations that experience natural hazard evacuations: communities in the Karrat Fjord in Greenland facing the possibility of rockslides and tsunamis, which has led to evacuation and resettlement; Rauma in Norway and its possibility of rockslides and repeated evacuation; Longyearbyen in Svalbard; and Honningsvåg in Norway, with its seasonal snow avalanche risks.

Existing risk quantification methods, such as the Bowtie method, are not directly applicable to health risk management due to their organizational design and inherent limitations. Managing health risks involves human judgment, localized intervention, and contextual constraints in implementing both preventive and mitigative measures. This study presents a novel framework for risk modeling with the Bowtie method to compute health risk management metrics, specifically applied to decision support systems for public health and safety. A mathematical model is formulated for each risk assessment metric parameterized by the weights assigned to each threat, consequence, and barrier, and a quasi-quantitative parameter is incorporated as an appropriate alternative to barrier escalation factors. The weights are computed through the Analytic Hierarchy Process (AHP) using survey data from questionnaires, supported by expert opinion and scientific findings from the systematic literature review. A case study of the COVID-19 pandemic demonstrated the efficacy of the proposed Health Risk Spectrum (HRS) metric in evaluating relevant risks across major regions of Mindanao Island, Philippines. The results show trends in the HRS metric above the floor of uncertainty, providing critical information to decision-makers for implementing appropriate interventions. The proposed Bowtie quantification framework is designed for broader application to various health risks, supporting proactive public health and safety decision-making.</div></div>","PeriodicalId":21375,"journal":{"name":"Safety Science","volume":"185 ","pages":"Article 106777"},"PeriodicalIF":4.7,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143156353","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}

The current study tests cognitive failures as an explanatory mechanism for the relationship between FWC and workplace accidents and injuries.

Using lagged data from a sample of N = 196 U.S. employees and cross-sectional data from a sample of N = 814 individuals nested within n = 100 organizations in Italy, results indicate that greater FWC and higher FWST are both related to increased work-related cognitive failures; such cognitive failures are related to more experienced accidents and injuries at work. Notably, within the U.S., these relationships are significantly exacerbated among employees who fear they are confirming negative stereotypes about employees with family obligations.
