This issue of poor fitting PPC for women in the structural and wildland fire service is largely due to a lack of available anthropometric data specific to the female firefighter population in the United States. This study consists of a comparative anthropometric analysis to investigate whether female firefighters in the United States are significantly different from the general female population, with the aim of enhancing the design and fit of female firefighting PPC. <em>Methods:</em> Utilizing mobile-app-based 3D body scanning technology, body measurements from 187 female firefighters were collected across the United States. These data were compared to the USA Size North America survey. Key measurements such as bust, height, waist, hip, and other circumferential and vertical dimensions were analyzed. Descriptive data for these measurements are presented and significant differences between the two databases were statistically tested. Additionally, the distribution and correlations among the key body measurements were evaluated to inform sizing recommendations for female firefighter PPC. <em>Results:</em> Female firefighters are generally taller than the U.S. female population by 6.7 cm, on average, and possess wider waists and hips, suggesting a more uniform upper body shape. Significant differences in secondary measures, such as leg inseam length and center back waist length, highlight the necessity of developing a female-firefighter-specific sizing system. <em>Conclusions:</em> This study underscores the limitations of PPC designed utilizing general population data alone, which fails to capture the unique anthropometric needs of female firefighters. This research advocates for a specialized approach to PPC design and sizing to improve the fit, performance, and safety of female firefighters. Additional research with larger sample sizes is recommended to validate these findings and refine the sizing system. <em>Practical application:</em> The comparative anthropometric analyses in this study will aid personal protective equipment (PPE) manufacturers in designing patterns for women’s firefighting PPC. Sufficient, but not excessive length coverage, should be considered when referring to the general female population’s sizing system. The next step in expanding the female firefighter body scan database will provide a unique and updated resource for designing better fitting and appropriately sized protective clothing for female firefighters in the United States.</div></div>","PeriodicalId":48224,"journal":{"name":"Journal of Safety Research","volume":"93 ","pages":"Pages 206-213"},"PeriodicalIF":3.9,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143488251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Machine learning (ML) models in crash severity studies have attracted much attention recently due to their promising predicted performance.

Furthermore, the interpretable ML approach, Shapley Additive explanation (SHAP), approach is employed to quantify the individual and interaction effects of risk factors based on the predicted results. Significant risk factors are identified, including airbag, crash type, posted speed limit and grade percentage. With the SHAP method, the individual effects and interaction effects of risk factors are explored. It is observed that roadways in rural (urban) had positive (negative) effects on the crash severity.

In spite of this, there is relatively little analysis on snow or ice- related slips, trips and falls among workers in the workers’ compensation system. This analysis aimed to describe the frequency, characteristics, and occupational burden of snow or ice-related slip, trip, or fall (STF) claims in Wisconsin. <em>Methods:</em> This study is a descriptive analysis of working age adults’ snow or ice-related STF lost time claims during the months of October through April for the years 2016–2022. <em>Results:</em> A total of 7,385 claims were reported, which represented 33.1% of all STF injuries. The overall claim rate during the study period was 2.65 claims per 1,000 workers (95% CI: 2.60 – 2.71). Workers aged 45 years or more had the highest risk. Fracture of lower leg, including ankle (20.3%), intracranial injury (10.7%), and fracture of the forearm (7.3%) were the most frequent primary diagnoses among hospitalized cases or seen in the emergency room.

However, the severity of injuries is often influenced by road conditions. <em>Method:</em> Data mining techniques, in particular Association Rule Mining (ARM), help to uncover non-trivial patterns in crash data, providing essential information for effective countermeasures to improve road safety and reduce crash severity. Using ARM, this study analyzes the relationship between crash severity and factors such as road deficiencies identified during safety inspections (Element Subject to Improvement or ESI) on two roads in Spain. <em>Results:</em> The primary findings reveal a strong link between vulnerable road users (pedestrians, cyclists, and motorcyclists) and crash severity. These results align with the Strategic Plan of the Basque Country, which aims to reduce severe road injuries by 50% by 2030, identifying the need for specific interventions to protect this type of user. Pedestrian casualty crashes are linked to inadequate restraint systems, while bicycle-related crashes are associated with glare from road orientation, inadequate shoulders, and inappropriate barriers. Unchanneled access points on roads also pose risks for cyclists. For motorcycles, factors such as inadequate speed limitations, poor shoulder design, and obsolete or inadequate restraint systems are strongly associated with crash severity. Poor signage, illegible road markings, water accumulation, and inadequate transport stops further contribute to increased crash severity. <em>Conclusions and practical applications:</em> Based on these findings, key countermeasures should focus on protecting vulnerable road users. Recommendations include installing pedestrian-friendly barriers and clear pedestrian pathways, widening shoulders, implementing anti-glare barriers for cyclists, and adding motorcycle-friendly restraint systems. Dynamic speed controls and better road signage are critical for reducing risks to motorcyclists. Other important measures include improving drainage systems to prevent water accumulation and redesigning public transport stops for safer bus merging areas. These targeted interventions can significantly reduce crash severity and support broader road safety goals.</div></div>","PeriodicalId":48224,"journal":{"name":"Journal of Safety Research","volume":"93 ","pages":"Pages 99-134"},"PeriodicalIF":3.9,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143445067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
