Aim: This case report presents an approach to establishing an occupational safety and health (OSH) plan for locally-hired office workers in construction supervision. Though not directly involved in construction, these workers face indirect exposure to site hazards, yet are often excluded from safety management systems. Methods: At a public construction site in Seoul, a customized OSH plan was implemented for one administrative staff member. It included targeted safety training, hazard assessment of adjacent equipment, and documentation practices. Coordination between headquarters and field staff supported consistent execution. Results: All training was delivered as scheduled, with risks like equipment overloads identified and resolved. A reporting and documentation system was also established. The case showed that even a single office worker can be integrated into a formal OSH framework. Conclusion: The study supports expanding OSH plans to all personnel on-site. A structured plan improves safety for administrative staff and offers a model applicable to similar field conditions.

Purpose: To identify factors influencing heat-illness prevention behaviors among construction workers, focusing on awareness of perceived-temperature measurement, recognition of temperature difference/necessity, experience of work adjustment or stoppage, and prevention awareness. Methods: In May 2025, 199 workers (aged 20–64) from six construction sites in Pyeongtaek, Korea, completed a mobile survey during routine safety education. Descriptive statistics, t-tests, ANOVA, Pearson correlations, and multiple regression were performed (SPSS/WIN 25.0; α=.05). Results: Prevention behaviors were higher among those aware of perceived-temperature measurement (t=2.72, p=.007). Prevention behaviors correlated with recognition of temperature difference/necessity (r=.303, p<.001), work adjustment/stoppage (r=.612, p<.001), and prevention awareness (r=.844, p<.001). Multiple regression indicated that prevention awareness (β=.686, p<.001), work adjustment/stoppage (β=.261, p<.001), and awareness of perceived-temperature measurement (β=.093, p=.014) significantly predicted prevention behaviors (F=41.53, p<.001; adjusted R²=.766). Conclusion: Enhancing prevention awareness, institutionalizing temperature monitoring, and formalizing work-adjustment/stoppage procedures may strengthen preventive behaviors at construction sites.

Purpose: This study aimed to examine workers’ understanding of occupational health-related risk assessment items and to identify differences according to tenure and job position. Methods: A total of 348 workers from various industries participated in a survey assessing understanding across seven domains of health-related risk assessment: job stress, cardiovascular disease, emotional labor, heat exposure, cold exposure, physical burden, and non-routine work. Reliability for each domain was verified using Cronbach’s α (.95–.98). Descriptive statistics, Pearson correlation analysis, one-way ANOVA, and independent t-tests were performed using SPSS 27.0 to identify differences by tenure and job position. Results: Significant differences in understanding were observed across both tenure and job position (p<.001). Workers with less than five years of tenure showed higher levels of understanding compared with those with 5–10 years and ten or more years of experience across all domains. Similarly, employees below the team leader level demonstrated significantly greater understanding than those in managerial positions. Conclusion: Workers’ understanding of health-related risk assessment items varies according to tenure and job position, underscoring the need for tailored education and strengthened leadership involvement. Periodic refresher training and case-based learning are recommended to reinforce understanding of health-related risks, while managerial training should emphasize organizational responsibility, legal accountability, and safety leadership. These findings provide foundational evidence for promoting workplace health and safety culture and for developing differentiated strategies to enhance the implementation of health-related risk assessments across diverse occupational environments.

Purpose: This study aims to provide baseline data for developing occupational safety and health policies tailored to industrial characteristics by comparing and analyzing the safety and health management systems of the construction and manufacturing industries using the 2015 Occupational Safety and Health Survey data. Methods: A total of 3,000 worksites (1,000 in construction and 2,000 in manufacturing) were selected as analysis subjects from the 2015 Occupational Safety and Health Survey. Workplace and worker characteristics, hazardous factors, safety and health management systems, and safety and health education status were surveyed. Differences between industries were verified using chi-square tests and independent samples t-tests. Results: The construction industry had a higher proportion of non-regular workers (469.6 vs. 5.9, p<.001), with particularly more elderly non-regular workers. Regarding hazardous factor exposure, the construction industry showed significantly higher exposure rates to dangerous workplaces (71.9% vs. 16.0%), ergonomic hazards(71.1% vs. 60.0%), and psychosocial hazards (33.8% vs. 23.1%) compared to the manufacturing industry (all p<.001). In terms of safety and health management systems, the construction industry's investment level (17,168 million won) was 6.7 times higher than manufacturing (2,573 million won) (p<.001). Regarding safety and health education, the construction industry focused on new employee group training (36.1 hours vs. 18.3 hours, p<.001), but education for work content changes (16.9 hours vs. 36.7 hours, p<.001) and non-statutory education (20.8 hours vs. 73.1 hours, p<.001) were significantly lacking. Conclusion: The construction industry faces fundamentally different conditions from the manufacturing industry in terms of employment instability, hazard characteristics, and education systems. Safety and health management in the construction industry needs to shift away from a safety-focused approach toward strengthened health management, establishment of continuous education systems, and industry-specific policies considering aging workers and increasing foreign workers. However, since this study is based on single-point data from 2015, future research using time-series data to verify the effects of policy improvements and qualitative research to identify actual barriers is required.
