As recent disasters, such as Chernobyl and JCO accident, indicated the importance of safety culture to protect organizations from a fatal damage, electric power utilities have continued to make efforts to enhance safety culture in the organizations. However, the efforts were beset with difficulties due to insufficiencies of how to implement it for practice. For providing the practical approaches, it is necessary to clarify organizational problems in each utility and to distinguish the difference between safety management conducted in safe companies and that in the utility. Hence, an investigation was conducted to clarify characteristics of organizational culture and safety management using a Japanese electric power company and contractors engaged in maintenance at thermal power plants, aiming at suggesting practical approaches to enhance safety. As a result, it was suggested that both companies' workers had high safety consciousness and also that safety education system and system dealing with accidents had been constructed. However, the followings were clarified as problems, i.e., 1) employees' commitment to safety activities is not adequately valued by managers and executives, 2) safety consciousness does not emerge as proactive behavior to prevent accidents, 3) procedures and information management have not been standardized nor constructed systematically in contract companies. In addition, the differences were observed of workers' safety consciousness, labor accidents and safety activities among three plants. According to the results, appropriate measures to be taken for safety were suggested to each company.
