Description: This study identified the increasing trend of night work among workers and the corresponding rise in the number of accidents, thereby confirming the need for improvements in safety and health aspects for night workers. Therefore, the purpose of this study is to propose measures to reduce industrial accident rates and improve safety and health levels by analyzing the safety and health status of night work and suggesting corresponding management strategies. The subjects of the study were 4,793 workplaces selected from among the targets of the 10th Occupational Safety and Health Survey, specifically those with a proportion of night shift workers less than or equal to 20% and greater than or equal to 80%. Six analysis indicators were designed using the Industrial Safety and Health Act and KOSHA-MS, and 40 survey questions corresponding to each indicator were applied. The analysis was conducted using the IPA Matrix (Importance-Performance Analysis Matrix) method. As a result of the study, it was found that in 39 out of the 40 variables, the safety and health levels of workplaces with 80% or more night shift workers were relatively low. In the quadrant distribution of the IPA Matrix, it was also found that 12% more variables were distributed in the first quadrant, which represents high importance and low safety and health performance. It is considered that policies reflecting the characteristics of night work-where direct supervision is difficult and there is often a reliance on pre-established safety rules and procedures-should be implemented. Furthermore, the structural vulnerabilities identified in night work environments through this study are expected to be used at the enterprise level as indicators for preventing industrial accidents.
