Abstract This study statistically verifies the quantitative relationship between hazard energy and injury severity using 1,508 construction accident cases from Korea’s Construction Safety Management Integrated Information System (CSI), and derives injury severity classification thresholds by energy type. To address the limitations of prior Energy-Based Safety (EBS) research which relied on small-scale datasets focused predominantly on potential and kinetic energy, five energy types were quantified: potential energy, kinetic energy, electrical energy, pressure energy, and mechanical energy. Kruskal?Wallis tests confirmed statistically significant relationships between energy magnitude and injury severity across all five energy types (p < 0.001). Furthermore, injury severity threshold values for each energy type were derived using Dunn’s test, ordinal logistic regression, and ROC analysis based on Youden’s J statistic. Additional logistic regression analysis incorporating personal protective equipment (PPE) and safety barrier conditions revealed that strengthened safety barriers significantly reduced the probability of fatal injuries. By validating the quantitative relationship between hazardous energy and injury severity using large-scale construction accident data, this study extends the empirical foundation of EBS and provides practical implications for quantitative risk assessment and real-time safety management systems in construction sites.
