In recent years, the requirement for pre-inspection of ventilation hole has been recognized as one of the important subject. Therefore, the objective of this study is to propose the methodology to prevent safety accident by systematically organizing problems of precision diagnosis of maintenance phase and considering the condition for disasters that occur at construction site. This study aims to show the diverse characteristics of safety accidents based on KOSHA's annual cases on disasters(electric shock, collapse, fail, suffocation, fall, breakdown) from 1993 to 2010. To achieve these objectives, we first examined the relationship between safety risk factors and root cause materials. We then systematically suggested the methodology for the priority management through the analysis of the primary problems of safety management and organized the safety inspection measures of ventilation hole in maintenance phase.
