Background

Workers are often exposed to hazardous heat due to their work environment, leading to various injuries. As a result of climate change, heat-related injuries (HRIs) are becoming more problematic. This study aims to identify critical contributing factors to the severity of occupational HRIs.

Methods

This study analyzed historical injury reports from the Occupational Safety and Health Administration (OSHA). Contributing factors to the severity of HRIs were identified using text mining and model-free machine learning methods. The Multinomial Logit Model (MNL) was applied to explore the relationship between impact factors and the severity of HRIs.

Results

The results indicated a higher risk of fatal HRIs among middle-aged, older, and male workers, particularly in the construction, service, manufacturing, and agriculture industries. In addition, a higher heat index, collapses, heart attacks, and fall accidents increased the severity of HRIs, while symptoms such as dehydration, dizziness, cramps, faintness, and vomiting reduced the likelihood of fatal HRIs.

Conclusions

The severity of HRIs was significantly influenced by factors like workers’ age, gender, industry type, heat index , symptoms, and secondary injuries. The findings underscore the need for tailored preventive strategies and training across different worker groups to mitigate HRIs risks.

背景由于工作环境的原因,工人经常暴露在危险的高温环境中,从而导致各种伤害。由于气候变化,与热有关的伤害(HRIs)问题日益严重。本研究旨在找出导致职业性热相关损伤严重程度的关键因素。方法本研究分析了职业安全与健康管理局(OSHA)的历史损伤报告。使用文本挖掘和无模型机器学习方法确定了导致人力资源损伤严重程度的因素。结果表明,中年、老年和男性工人发生致命 HRI 的风险较高,尤其是在建筑、服务、制造和农业等行业。此外,较高的热指数、晕倒、心脏病发作和跌倒事故会增加 HRI 的严重程度,而脱水、头晕、痉挛、晕厥和呕吐等症状则会降低致命 HRI 的可能性。结论 HRI 的严重程度受工人的年龄、性别、行业类型、热指数、症状和二次伤害等因素的显著影响。研究结果表明,有必要针对不同的工人群体制定有针对性的预防策略和培训,以降低高热损伤的风险。

Background

The design, implementation, and evaluation are three important stages of occupational safety and health (OSH) interventions. Historically, there has been a tendency to prioritize implementation, often neglecting detailed design and rigorous outcome evaluation. Currently, much has changed, and contemporary approaches recognize the interdependence of these stages, considering them integral to the success of any intervention. This work presents a comprehensive procedure for implementing interventions, not only to ensure short-term effectiveness but also their long-term sustainability through continuous monitoring. The focus is on a national OSH project introducing a near-miss management system (NMS) in Italy.

Methods

Initial meetings were convened among project partners, complemented by interviews with diverse stakeholders, to plan implementation steps and test the NMS. Tailored questionnaires were designed for diverse stakeholder groups – initial promoters, company managers and employers, and employees – facilitating targeted implementation, and three case studies were started in Italian regions to assess the structured implementation, involving intervention promoters and collaborating companies.

Results

The primary outcome is the development of practical tools, specifically three questionnaires, which are considered valuable for establishing an effective human-centered implementation strategy, meticulously designed to facilitate ongoing monitoring of processes and continual enhancement of instruments intended for NMS integration within companies.

Conclusions

This work lays the foundation for successful NMS implementation in Italy and, although the outlined procedure had specific objectives, it also provides valuable insights applicable in enhancing the effectiveness and sustainability of interventions across diverse contexts. It underscores the importance of comprehensive planning, stakeholder engagement, and continuous evaluation in achieving lasting OSH interventions.

背景设计、实施和评估是职业安全与健康(OSH)干预措施的三个重要阶段。一直以来,人们倾向于优先考虑实施,而往往忽视了详细的设计和严格的结果评估。目前,情况已经发生了很大变化,当代的方法已经认识到这些阶段的相互依存性,认为它们是任何干预措施取得成功不可或缺的因素。这项工作提出了实施干预措施的综合程序,不仅要确保短期效果,还要通过持续监测确保干预措施的长期可持续性。方法在项目合作伙伴之间召开初步会议,并对不同的利益相关者进行访谈,以规划实施步骤和测试 NMS。针对不同的利益相关者群体--最初的推动者、公司经理和雇主以及员工--设计了量身定制的调查问卷,以促进有针对性的实施,并在意大利各地区开展了三项案例研究,以评估结构化实施情况,其中涉及干预推动者和合作公司。结果主要成果是开发了实用工具,特别是三份调查问卷,这些工具被认为对建立有效的以人为本的实施战略非常有价值,其精心设计有助于对流程进行持续监控,并不断改进旨在将国家管理系统纳入公司内部的工具。它强调了全面规划、利益相关者参与和持续评估对于实现持久的职业安全和健康干预的重要性。

Background

Traffic accidents involving professional drivers have serious societal repercussions. Unique occupational stressors and health risks exacerbate the likelihood of traffic accidents among professional drivers. This study explores the association between presenteeism—impaired work performance due to working while unwell—and traffic accident risk among professional taxi drivers in Japan.

Methods

A prospective cohort study was conducted from June 2022 to February 2023, involving taxi drivers from a single company in Fukuoka Prefecture, Japan. Presenteeism was assessed using the Work Functioning Impairment Scale (WFun). Primary outcome involved the number of self-reported minor traffic accidents. The incidence rate ratio (IRR) of minor traffic accident occurrences was estimated using a Poisson regression analysis, adjusted for confounders including sex, age, and driving experience.

Results

Of 838 targeted drivers, 435 were included in the analysis. Higher baseline work functioning impairment was associated with a significant trend of increasing IRR of minor traffic accidents (p for trend = 0.045). A dose-response relationship was seen between the degree of presenteeism and incidence rate of minor traffic accidents.

Conclusion

Higher levels of presenteeism were associated with an increased risk of traffic accidents among taxi drivers. The findings underscore the need for socio-economic support and prioritized health management to mitigate traffic accident risk among professional drivers. This study highlights the importance of managing non-critical health issues alongside serious health conditions for safer driving practices among professional drivers in Japan.

背景涉及职业司机的交通事故会造成严重的社会影响。独特的职业压力和健康风险加剧了职业司机发生交通事故的可能性。本研究探讨了日本职业出租车司机的旷工现象--因在身体不适的情况下工作而导致的工作绩效受损--与交通事故风险之间的关联。 方法 在 2022 年 6 月至 2023 年 2 月期间进行了一项前瞻性队列研究,研究对象为日本福冈县一家公司的出租车司机。采用工作功能障碍量表(WFun)对旷工情况进行评估。主要结果包括自我报告的轻微交通事故数量。在对性别、年龄和驾驶经验等混杂因素进行调整后,使用泊松回归分析估算了轻微交通事故的发生率比(IRR)。较高的基线工作功能障碍与轻微交通事故 IRR 的显著增加趋势相关(趋势的 p = 0.045)。旷工程度与轻微交通事故发生率之间存在剂量反应关系。研究结果表明,有必要提供社会经济支持和优先健康管理,以降低职业司机发生交通事故的风险。这项研究强调了在管理严重健康问题的同时管理非关键健康问题对于日本职业司机安全驾驶的重要性。

Background

Coal miners are highly prone to occupational health risks, such as black lung disease. This study aims to assess the prevalence of black lung disease and the factors associated with black lung disease among coal miners in Asia.

Method

This systematic review, conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, searched through the scientific literature of the following databases: EBSCO, ScienceDirect, PubMed, and Scopus. We selected articles that studied black lung disease among coal miners from 48 countries in Asia and were published between 2014 and 2023. Article quality was evaluated using the Critical Appraisal Skills Program.

Result

The seven articles that we review studied a total of 653,635 coal miners from various types of coal mines from three countries in Asia. Of these miners, 59,998 experienced black lung disease. Black lung disease is prevalent among 9.18% of coal miners in Asia, which is approximately four times higher than the worldwide prevalence. Common factors that influence black lung disease in Asia include age, years of dust exposure, smoking, drinking, working types, and sizes of mines, type of mines, respiratory functions, spirometry parameters, tenure, lack of attention to occupational health, inefficient surveillance, and weak occupational health service.

Conclusion

Although the prevalence of black lung disease among coal miners in Asia is considerably high, it can be addressed through effective prevention measures, monitoring, control, and case reporting.

Background

Webtoon, a digital form of comics created in the Republic of Korea, has spread widely with advantages that anyone can become a cartoonist and that autonomy of creation is guaranteed. The purpose of this study is to identify the working conditions of webtoon writers and analyze the relationship between these conditions and depressive symptoms.

Methods

A survey was carried out on webtoon writers and a survey data of 312 webtoon writers were analyzed. The questionnaire included basic socio-demographic characteristics, webtoon writers’ contractual type, fields of activity (webtoon creator, story writer, illustrator), and working environment (labor discretion etc.). We investigated depressive symptoms and analyzed its relation to the work environment of webtoon writers.

Results

Webtoon writers were exposed to long working hours, high labor intensity, limited labor discretion, negative comments from readers, and had a high prevalence of depressive symptoms. Compared to story writers who contracted directly with platforms, story writers and the illustrators who contracted with content providers (CPs) were 9.51 times (OR = 9.51, 95% CI = 1.47 - 61.33) and 6.47 times (OR = 6.47, 95% CI = 1.08 – 38.75) more likely to have depressive symptoms, respectively.

Conclusions

This study emphasizes the urgent necessity to improve the overall working environment in the webtoon industry and implement measures to tackle the escalating mental health challenges faced by illustrators and story writers contracted with CPs, especially given the increasing popularity of novel comics.

网络漫画(Webtoon)是大韩民国创作的一种数字形式的漫画,具有人人都能成为漫画家、创作自主性得到保障等优点,现已广泛传播。本研究旨在确定网络漫画作者的工作条件,并分析这些条件与抑郁症状之间的关系。本研究对网络漫画作者进行了调查,分析了 312 名网络漫画作者的调查数据。问卷内容包括基本社会人口特征、网络动漫作家的合同类型、活动领域(网络动漫创作者、故事作家、插图画家)和工作环境(劳动自由裁量权等)。我们调查了网络动漫作家的抑郁症状,并分析了其与工作环境的关系。网络动漫作家的工作时间长、劳动强度大、劳动自由裁量权有限、读者评价负面,因此抑郁症状的发生率较高。与直接与平台签约的编剧相比,与内容提供商(CP)签约的编剧和插画师出现抑郁症状的几率分别是后者的 9.51 倍(OR = 9.51,95% CI = 1.47 - 61.33)和 6.47 倍(OR = 6.47,95% CI = 1.08 - 38.75)。本研究强调了改善网络漫画行业整体工作环境的迫切性,以及采取措施解决与CP签约的插画师和编剧所面临的不断升级的心理健康挑战的必要性,尤其是在小说漫画日益流行的情况下。

Safety Data Sheets as a Hazard Communication Tool: An Assessment of Suitability and Readability 安全数据表作为危险交流工具:适用性和可读性评估
IF 3.5 3区 医学 Q1 PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH Pub Date : 2024-06-01 DOI: 10.1016/j.shaw.2024.01.006
Kevin Ho, Thomas Tenkate

Background

Safety data sheets (SDSs) are hazard communication materials that accompany chemicals/hazardous products in the workplace. Many SDSs contain dense, technical text, which places considerable comprehension demands on workers, especially those with lower literacy skills. The goal of this study was to assess SDSs for readability, comprehensibility, and suitability (i.e., fit to the target audience).

Methods

The Suitability Assessment of Materials (SAM) tool assessed SDSs for suitability and readability. We then amended the SAM tool to further assess SDSs for comprehensibility factors. Both the original and amended SAM tool were used to score 45 randomly selected SDSs for content, literacy demand, graphics, and layout/typography.

Results

SDSs performed poorly in terms of readability, suitability, and comprehensibility. The mean readability scores were Flesch–Kincaid Grade Level (9.6), Gunning Fog index (11.0), Coleman–Liau index (13.7), and Simple Measure of Gobbledygook index (10.7), all above the recommended reading level. The original SAM graded SDSs as “not suitable” for suitability and readability. When the amended SAM was used, the mean total SAM score increased, but the SDSs were still considered “not suitable” when adding comprehensibility considerations. The amended SAM tool better identified content-related issues specific to SDSs that make it difficult for a reader to understand the material.

Conclusions

In terms of readability, comprehensibility, and suitability, SDSs perform poorly in their primary role as a hazard communication tool, therefore, putting workers at risk. The amended SAM tool could be used when writing SDSs to ensure that the information is more easily understandable for all audiences.

背景安全数据表(SDS)是工作场所化学品/危险产品随附的危害告知材料。许多安全数据表包含密集的技术性文字,这对工人的理解能力提出了相当高的要求,尤其是那些识字能力较低的工人。本研究的目标是评估安全数据单的可读性、可理解性和适用性(即是否适合目标受众)。方法材料适用性评估(SAM)工具评估安全数据单的适用性和可读性。然后,我们对 SAM 工具进行了修订,以进一步评估 SDS 的可理解性因素。我们使用原始和修正后的 SAM 工具对随机抽取的 45 份 SDS 进行了内容、读写能力要求、图形和布局/排版方面的评分。可读性的平均得分如下Flesch-Kincaid等级(9.6)、Gunning-Fox指数(11.0)、Coleman-Liau指数(13.7)和SMOG指数(10.7),均高于建议的阅读水平。原来的 SAM 将安全数据单的适用性和可读性评为 "不适合"。使用修订后的 SAM 后,SAM 的平均总分有所提高,但如果再加上可读性方面的考虑,SDS 仍被视为 "不合适"。结论 在可读性、可理解性和适用性方面,安全数据单在发挥其作为危险交流工具的主要作用方面表现不佳,因此给工人带来了风险。在编写安全数据单时,可以使用经修订的 SAM 工具,以确保所有受众都能更容易地理解信息。

Background

Glove reuse poses risks, as chemicals can persist even after cleaning. Decontamination methods like thermal aeration, recommended by US OSHA, vary in effectiveness. Some studies show promising results, while others emphasize the importance of considering both permeation and tensile strength changes. This research advocates for informed glove reuse, emphasizing optimal thermal aeration temperatures and providing evidence to guide users in maintaining protection efficiency.

Methods

The investigation evaluated Neoprene and Nitrile gloves (22 mils). Permeation tests with toluene and acetone adhered to American Society for Testing Materials (ASTM) F739 standards. Decontamination optimization involved aeration at various temperatures. The experiment proceeded with a maximum of 22 re-exposure cycles. Tensile strength and elongation were assessed following ASTM D 412 protocols. Breakthrough time differences were statistically analyzed using t-test and ANOVA.

Results

At room temperature, glove residuals decreased, and standardized breakthrough time (SBT)2 was significantly lower than SBT1, indicating reduced protection. Higher temperature decontamination accelerated residual removal, with ΔSBT (SBT2/SBT1) exceeding 100%, signifying restored protection. Tensile tests showed stable neoprene properties postdecontamination. Results underscore thermal aeration's efficacy for gloves reuse, emphasizing temperature's pivotal role. Findings recommend meticulous management strategies, especially post-breakthrough, to uphold glove-protective performance.

Conclusions

Thermal aeration at 100°C for 1 hour proves effective, restoring protection without compromising glove strength. The study, covering twenty cycles, suggests safe glove reuse with proper decontamination, reducing costs significantly. However, limitations in chemical-glove combinations and exclusive focus on specific gloves caution against broad generalization. The absence of regulatory directives on glove reuse highlight the importance of informed selection and rigorous decontamination validation for workplace safety practices.

手套的重复使用会带来风险,因为化学品即使在清洗后也会残留。美国职业安全与健康管理局推荐的热曝气等去污方法的效果各不相同。一些研究显示了良好的效果,而另一些研究则强调了同时考虑渗透性和拉伸强度变化的重要性。这项研究提倡在知情的情况下重复使用手套,强调最佳热曝气温度,并提供证据指导用户保持防护效率。调查评估了氯丁橡胶和丁腈手套(22 密耳)。甲苯和丙酮的渗透测试符合美国材料试验协会(ASTM)的标准。去污优化包括在不同温度下进行曝气。实验最多进行了 22 次再暴露循环。拉伸强度和伸长率按照 ASTM D 412 协议进行评估。使用-检验和方差分析对突破时间差异进行了统计分析。在室温下,手套残留物减少,标准突破时间(SBT)明显低于 SBT,表明保护能力降低。高温去污加速了残留物的清除,ΔSBT(SBT/SBT)超过了 100%,表明保护能力得到恢复。拉伸测试表明,去污后氯丁橡胶性能稳定。研究结果强调了热曝气对手套重复使用的功效,并强调了温度的关键作用。研究结果建议采取细致的管理策略,尤其是在破损后,以保持手套的保护性能。在 100°C 温度下通气 1 小时证明是有效的,在不影响手套强度的情况下恢复了保护性能。这项研究覆盖了二十个周期,建议在适当去污的情况下安全重复使用手套,从而大幅降低成本。不过,由于化学品与手套组合的局限性以及只关注特定手套,因此不能一概而论。目前还没有关于手套重复使用的监管指令,这凸显了在工作场所安全实践中进行知情选择和严格去污验证的重要性。

Background

We examined the association between supervisor consultation, as an actual practice representing supervisor support, and work engagement.

Methods

This was a prospective cohort study in Japan, involving 14,026 participants who met the requirement for a one-year follow-up. Supervisor consultation was measured using a single question, and work engagement was defined using the Japanese version of the nine-item Utrecht Work Engagement Scale (UWES-9). Associations were examined using linear regression analysis.

Results

Supervisor consultation was positively associated with work engagement after adjusting for gender, age, education, income, and industry (β = 3.474; p < 0.001). The relationship remained significant after adjustment for perceived supervisor support, although the coefficient decreased (β = 1.315; p < 0.001).

Conclusion

Supervisor consultation probably acted on work engagement in different ways than perceived supervisor support.

方法这是一项在日本进行的前瞻性队列研究,共有 14,026 名符合一年随访要求的参与者参与其中。督导咨询采用单一问题进行测量,工作投入度采用九项乌特勒支工作投入度量表(UWES-9)的日文版进行定义。结果在对性别、年龄、教育程度、收入和行业进行调整后,主管咨询与工作投入呈正相关(β = 3.474; p < 0.001)。结论上司咨询与上司支持可能以不同的方式对工作投入度产生影响。

Background

Gasoline, a complex mixture of volatile organic compounds is classified as possibly carcinogenic to humans. Gasoline station attendants, consistently exposed to its hazardous components, may face genotoxic effects. This study aimed to assess the influence of varying work shift durations on DNA damage in gasoline station attendants.

Methods

Ninety individuals from three locations in southern México were studied. Peripheral blood mononuclear cells (PBMCs) were isolated, and DNA damage was assessed using the comet assay. Demographic, occupational, and lifestyle data were collected. Statistical analyses included t-tests, ANOVA, and Pearson correlation.

Results

Significant differences in DNA damage parameters were observed between exposed and unexposed groups. The impact of tobacco, alcohol, and exercise on DNA damage was negligible. Extended work shifts (12 and 24 hours) showed heightened DNA damage compared to 8-hour shifts and the unexposed group. A novel finding revealed a modest but significant correlation between DNA damage and job seniority.

Conclusion

The study highlights the intricate relationship between occupational exposure to gasoline components, DNA damage, and work shift lengths. Extended shifts correlate with heightened genotoxic effects, emphasizing the importance of personalized safety measures. The significant correlation between DNA damage and job seniority introduces occupational longevity as a determinant in the genetic health of gasoline station attendants. This discovery has implications for implementing targeted interventions and preventive strategies to safeguard workers' genetic integrity throughout their years of service. The study calls for further exploration of unconsidered factors in understanding the multifactorial nature of DNA damage in this occupational setting.

背景汽油是一种挥发性有机化合物的复杂混合物,被列为可能对人体致癌的物质。加油站服务员长期接触汽油中的有害成分,可能会受到基因毒性的影响。本研究旨在评估不同轮班时间对加油站服务员 DNA 损伤的影响。分离了外周血单核细胞(PBMC),并使用彗星试验评估了 DNA 损伤情况。还收集了人口统计学、职业和生活方式数据。统计分析包括 t 检验、方差分析和皮尔逊相关分析。烟草、酒精和运动对 DNA 损伤的影响微乎其微。与 8 小时轮班和未暴露组相比,延长轮班时间(12 小时和 24 小时)导致的 DNA 损伤更为严重。一项新的发现表明,DNA损伤与工龄之间存在微弱但显著的相关性。延长轮班时间与基因毒性效应增加有关,强调了个性化安全措施的重要性。DNA 损伤与工作年限之间的明显相关性将职业寿命作为加油站服务员遗传健康的一个决定因素。这一发现对实施有针对性的干预和预防策略,以保障工人在整个工作年限内的基因完整性具有重要意义。这项研究要求进一步探索未被考虑的因素,以了解这种职业环境中 DNA 损伤的多因素性质。
