Based on consultation with stakeholders, pickups and vans appear to pose problems when raised using two-post above-ground lifts (2PAG lifts), the most common type of automotive lift in garages. The aim of this study is therefore to highlight the work activity performed by mechanics when raising pickups and vans on 2PAG lifts and to describe the factors they take into account to ensure vehicle stability. Data collection took place under actual conditions in five garages. A total of 108 lifting situations were filmed and analyzed, of which nine involved pickups and vans. Using a multidisciplinary ergonomic-engineering approach, the field results were then discussed and compared with measures obtained previously in a controlled environment. The indicators of difficulty identified during the lifting were more prevalent for pickups and vans (89%) than for other vehicle categories (59%). In addition, the total capacity of the lift appears to be an insufficient indicator of safety for this type of vehicle. For example, due to lift-vehicle geometry, the rear lift arms could support around 70% of the total load when a pickup is loaded in the cargo area, with each rear arm potentially exceeding 25% of the lift's rated capacity. Also, lifting points usually create a rear overhang that induces rocking, generating load fluctuations of up to 510 kg-force on the front support pads. Recommendations are made for vehicle manufacturers and 2PAG lift manufacturers, as well as for garage personnel.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"3 1","pages":"Pages 37-49"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147757115","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}

Despite increasing recognition that ERW risks may intensify over time due to munition degradation, environmental change, and expanding human activity, risk management practices continue to rely largely on conventional, probability-based risk assessment. In ERW contexts, however, weak prior knowledge, deep uncertainty, and complex socio-technical interactions limit the practical value of probabilistic approaches and may foster a false sense of control. This paper argues that organisational resilience (OR) provides a necessary complement to conventional risk management in high-hazard domains characterised by irreducible uncertainty. Drawing on an uncertainty-centred conception of risk and a capability-based framework of organisational resilience, the study examines how anticipation, coping, and adaptation shape ERW risk management across strategic, operational, and tactical levels. The analysis is informed by a qualitative case study from the Norwegian defence sector, based on interviews, document analysis, and practitioner experience. The findings show that ERW risk management challenges are not solely technical, but reflect limitations in organisational capabilities to anticipate emerging threats, cope with disruptions when they occur, and learn and adapt over time. By explicitly integrating resilience and risk perspectives, the paper demonstrates how safety performance can be strengthened when probabilistic risk assessment is insufficient. The study contributes to safety science by providing a coherent framework for analysing and improving safety management in ERW contexts and other complex, high-uncertainty risk environments.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"3 1","pages":"Pages 82-92"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147757120","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}

Despite these long-standing safe-sleep guidelines, the juvenile products industry marketed inclined sleepers for over a decade. In 2019, the industry recalled several million of the devices due to numerous reports of infant deaths being associated with the products. The hazards of inclined sleepers can be understood and evaluated through an analysis of the physical structure combined with a biomechanical analysis of the infants placed into the devices. Several hazards unique to inclined sleepers, that are not present in flat cribs, are identified in this study. Key hazards include infants rolling supine-to-prone, the feet of prone infants losing contact with the sleeping surface, infant faces in contact with non-breathable fabric, infant arms trapped by steep sidewalls, and unsafe restraint systems that are easily misused by caregivers. This paper presents a first-principles biomechanical-based hazard analysis integrated with a fault tree analysis. The biomechanical analyses incorporating root-cause reasoning for the hazard mechanisms may serve to guide the design and improve the safety of future products. Furthermore, an important conclusion is that adhering to industry standards does not guarantee hazard mitigation for the diverse forms of products within any given category.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"3 1","pages":"Pages 23-36"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147757117","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}

In theoretical studies of stress wave propagation, the slope model is often simplified, neglecting the vibration superposition effect due to multiple reflections between the slope surface and structural planes, as well as the attenuation of stress wave caused by viscoelasticity of rock mass. Based on the time domain recursive analysis method, the stress wave propagation analysis model was established for a viscoelastic rock slope with filled structural planes. This model incorporated quality factors of the stress wave and derived both the analytical equation for slope vibration and the expression for the slope amplification coefficient. Assuming the slope behaves as a Kelvin viscoelastic body, the normal deformation of the contact interface at the filled structural plane conforms to a nonlinear hyperbolic model, whereas the tangential deformation follows a linear model. The results indicate that, although multiple reflection waves in the rock mass amplify the slope's vibration effect, the viscoelastic properties of rock mass dampen this amplification, making it less significant. Furthermore, as both the slope inclination and the inclination of the filled structural plane increase, the slope amplification coefficient undergoes significant and nonlinear variations. As the coordinates of the monitoring points increase, the slope amplification coefficient initially undergoes abrupt fluctuations, gradually decreasing towards stability. Additionally, as the thickness of the filled structural plane increases, the slope amplification coefficient decreases progressively.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"2 4","pages":"Pages 257-267"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145842478","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}

Ice-coating disasters, characterized by sudden onset and wide impact, pose significant risks. Existing research focuses on pre-disaster prediction, in-disaster analysis, and post-disaster recovery but neglects the impact of ice-coating faults on the power supply capability. Therefore, this paper presents a model for assessing the Total Supply Capability (TSC) of distribution networks under extreme ice-coating disasters (unique aspects). First, a two-stage data-driven ice-coating fault prediction method is proposed, employing meteorological data analysis and the random forest algorithm to calculate the fault probability in distribution networks. Specifically, Stage 1 addresses sparse historical data by expanding the dataset, while Stage 2 uses a random forest model to predict single-feeder ice-coating fault rates. Second, a power supply capability model for ice-coating disasters is established, which enables a quantitative analysis of the capability and the probability of its loss. Next, a feeder risk-classification-based planning method is proposed, which optimizes load transfer paths via new tie-lines to enhance power supply capability. Finally, an extended IEEE_RBTS_BUS4 case validates the model's effectiveness. Compared to existing methods (practical application value and concrete achievable effects), our approach not only quantifies the impact of ice-coating on power supply capability but also identifies vulnerable feeders. This work provides effective guidance for planning and enhances distribution network reliability under extreme weather.</div></div>","PeriodicalId":100831,"journal":{"name":"Journal of Safety and Sustainability","volume":"2 4","pages":"Pages 285-292"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145842475","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}

Building on the multi-scale evolution mechanisms of key scenario states in chemical tank fires and the scenario-driven information requirements theory, a theoretical framework for situational information requirements tailored to tactical command decision-making is proposed.
