Currently, 76.6% of businesses in South Korea that are required to appoint safety managers have outsourced their safety management tasks to specialized safety management institutions. As a result, the role of these institutions is crucial. However, these institutions lack standardized inspection items for workplaces, and there are no specific regulations that enforce the improvement of identified risk factors in the submitted inspection reports. This leads to a low improvement rate and a lack of reduction in the accident rate. This study focuses on 10 businesses in the machinery, metallic, and non-metallic mineral products manufacturing industry in the southern region of Gyeonggi Province, South Korea. Over a period of three years, the contents of inspection reports submitted by these businesses were classified into six categories: mechanical factors, electrical factors, chemical(substance) factors, biological factors, task-specific factors, and work environment factors, according to the Korea risk assessment system(KRAS) classification. Regression analysis and Pearson correlation analysis were conducted to find out the relationship between the improvement rate and the accident rate. The results of the regression analysis confirmed that the improvement rate of risk factors provided by specialized safety management institutions significantly affects the accident rate in the workplace. The correlation analysis results indicate a significant correlation between the improvement rates and accident rates of the five factors excluding biological factors for which no inspection items were identified. Based on these findings, the study identified inspection items within the reports that had a low improvement rate and were repeatedly pointed out. Additionally, priority improvement items were derived based on the industry's characteristics. This study proposes checklists that can be utilized for safety inspections in the machinery, metallic, and non-metallic mineral products manufacturing industry. It is expected that by utilizing these safety inspection checklists, the accident rate in these workplaces can be reduced.

机械、金属、非金属矿产品制造业事故率与KRAS分类风险因素改善率关系分析

目前，韩国76.6%需要任命安全管理人员的企业已将安全管理任务外包给专门的安全管理机构。因此，这些机构的作用至关重要。然而，这些机构缺乏对工作场所的标准化检查项目，对于提交的检查报告中发现的风险因素也没有具体的规定强制改进。这导致改善率低且事故率没有降低。本研究重点关注韩国京畿道南部地区机械、金属和非金属矿产品制造业的 10 家企业。三年来，这些企业提交的检查报告内容按照标准分为机械因素、电气因素、化学（物质）因素、生物因素、任务特定因素、工作环境因素六大类。韩国风险评估系统（KRAS）分类。进行回归分析和Pearson相关分析，找出改善率与事故率之间的关系。回归分析结果证实，专业安全管理机构提供的危险因素改善率显着影响工作场所事故发生率。相关分析结果表明，排除未确定检查项目的生物因素后，5个因素的改善率与事故率之间存在显着相关性。根据这些发现，研究确定了报告中改善率较低并被反复指出的检查项目。此外，还根据行业特点，导出了优先改进项目。本研究提出了可用于机械、金属和非金属矿产品制造业安全检查的检查表。预计通过利用这些安全检查表，可以降低这些工作场所的事故率。
