조선업 떨어짐재해 위험성평가에 관한 연구

Abstract

As comparing with various industries, the shipbuilding industry includes complex processes due to the characteristics of its work. Especially, there are movements between work procedures and lots of works at high place with the high frequency of exposure to dangerous working environment such as handling heavy materials and operation in confined space. For last ten years, the accident rate of shipbuilding industry has been 1.42, which is higher than that of the manufacturing industry(1.06). Also, in terms of the fatal accident rate per 10,000, the shipbuilding industry is 2.09, which is two times more than that of manufacturing industry(1.03). Also, the type of industrial accidents in the manufacturing industry includes caught between, tripping, collision, flying, and falling in the order. While the shipbuilding industry includes falling, tripping, collision, caught between, and flying in the order. Falling accidents take account for 23% of the whole industrial accidents in shipbuilding industry. Once a falling accident happens, the criticality is high, so that its period of treatment is long with the high probability of leading up to death. Therefore, this study aimed to understand the tendency of falling accidents by analyzing 667 industrial accidents(185 falling accidents) in the shipyard of S company and its internal subcontractor of Korea from 2004 to 2013, and also to suggest the measures based on the characteristics of falling accidents and causes for accidents through the risk assessment of falling accidents in each process. In the results of the study, falling accidents happened the most in the process of painting, erection, and assembly scaffolding. Also happening the most in the process of using a vertical ladder to move within ship blocks. In order to prevent falling accidents, it is important to conduct basic activities such as checking the condition of scaffolding by a supervisor before starting work, and installing the facility connecting to safety belts and wearing them in accordance with the work condition, and also to put efforts into the reduction of unnecessary high place work, unstable work posture, and unsafe behaviors. This study is expected to contribute to the prevention of falling accidents in the shipbuilding industry by using it as basic data when establishing measures to present falling accidents in the domestic shipbuilding industry.
