Abstract

This study is conducted to compare three methods of hazard analyses and to propose the control for the accidents arising under construction of heat accumulator of group energy projects(co-generation plants). The analysis of fatal accidents and the Analytic Hierarchical Process(AHP) using by the questionnaire survey for the workers engaged in the construction of heat accumulator and the quantitative questionnaire survey of expert group has been carried out. In order to analyze the fatal accidents, the 115 cases of accidents from 2001 to 2012 published by Korean Occupational Safety and Health Agency(KOSHA) and workers suffered from industrial accidents are collected and analyzed. The AHP is applied and analyzed for 66 persons of the construction site managers, safety engineers and construction engineers and the questionnaire survey of expert group is carried out and analyzed for the 51 persons of contractors and construction inspectors. The analyses of the types of accidents and the jobs of the suffered workers and the hazardous construction processes which are occurred accidents frequently are shown. The results of the analysis of fatal accidents and the AHP as well as the questionnaire of expert group are shown similar results.
