건설업에서 실외 열환경 및 열쾌적성과 산업재해의 관계에 대한 체계적 고찰

This study systematically examines the relationship between outdoor thermal environments, thermal comfort, and occupational accident risk in construction sites from 2021 to 2025, focusing on quantitative analyses. Following PRISMA guidelines, six studies were selected from 447 papers retrieved from Web of Science and Scopus. The results show a clear association between thermal conditions and accident occurrence. Extreme weather events, amplified by climate change, increase thermal stress among workers, thereby raising accident risk. Thermal comfort indices, particularly physiologically equivalent temperature, were strongly correlated with accidents, with risk increasing 2–3 times under conditions beyond the comfort range. These findings highlight thermal environment management as a key component of construction safety. Prior studies often relied on public accident and weather data, limiting the reflection of site-specific microclimates and individual factors. Future research should therefore focus on site-based meteorological monitoring, worker-specific thermal assessment models, and adaptive safety standards considering work type and season. This study provides empirical evidence for integrating thermal comfort into safety management, offering a foundation for proactive and climate-adaptive construction safety strategies. Despite the limited number and scope of studies, continued research and international comparisons are expected to broaden and refine our understanding of this topic
