Abstract
Background
The aim of this study was to develop a new Korean Construction Job Exposure Matrix (KoConJEM) for the construction industry based on 60 occupations consolidated by the Construction Workers Mutual Aid Association.
Methods
Evaluation of the probability, intensity, and prevalence of exposure as binary (Yes/No) or four categories (1–4) to 26 hazardous agents for 60 consolidated occupations was performed by 30 industrial hygiene experts. The risk score (1 to 16) was calculated by multiplying the exposure intensity by the prevalence of exposure. The JEM was expressed on a heatmap and a web-based dashboard to facilitate comparison of exposure characteristics according to each occupation and hazardous agent. Hierarchical cluster analysis (HCA) was applied for identification of similar patterns in exposure characteristics of different agents across occupations.
Results
Hazardous agents evaluated as exposure is probable by at least one or more experts in all occupations included awkward posture, heat/cold, heavy lifting, and noise. The hazardous agent with exposure in the smallest number of occupations (n = 5) was asphalt fumes. The highest risk value of 16 for awkward posture was observed for almost all occupations except safety officer. The results of HCA using risk values showed that the pattern for the welding-related occupational group differed the most from that of other occupational groups.
Conclusion
The KoConJEM provides information on the probability, intensity, and prevalence of exposure to harmful factors. It might be useful in the conduct of epidemiological studies on health risk assessment of construction workers.

Abstract
Background
This study was conducted as an effort to develop a Korean construction job exposure matrix (KoConJEM) based on 60 occupations recently consolidated by the construction workers mutual aid association for use by the construction industry.
Methods
The probability, intensity, and prevalence of exposure to 26 hazardous agents for 60 consolidated occupations were evaluated as binary (Yes/No) or four categories (1 to 4) by 30 industrial hygiene experts. The score for risk was calculated by multiplying the exposure intensity by the prevalence of exposure. Fleiss' kappa for each hazardous agent and occupation was used to determine agreement among the 30 experts. The JEM was expressed on a heatmap and a web-based dashboard to facilitate comparison of factors affecting exposure according to each occupation and hazardous agent.
Results
Awkward posture, heat/cold, heavy lifting, and noise were hazardous agents regarded as exposure is probable by at least one or more experts in all occupations, while exposure to asphalt fumes was considered hazardous in the smallest number of occupations (n = 5). Based on the degree of agreement among experts, more than half of the harmful factors and most occupations showed fair to good results. The highest risk value was 16 for awkward posture for most occupations other than safety officer.
Conclusions
The KoConJEM provides information on the probability, intensity, and prevalence of exposure to harmful factors, including most occupations employing construction workers; therefore, it may be useful in the conduct of epidemiological studies on assessment of health risk for construction workers.
