A Study on the Hazard Identification of Laboratory using 4M ＆ HAZOP

Department of Environmental Health Science, Soonchunhyang University(Received July 17, 2012 / Accepted April 30, 2013)Abstract : In university laboratories, areas of studies are becoming diverse and complicated according to the development of the industry. Newforms of potential risk factors are increasing and they are unlike existing ones. In addition, many students are conducting various experiments in the laboratory. Therefore, they could be exposed to risk more often. Despite these risks, people do not recognize university lab safety activities properly and observe safety precautions. They are exposed to various laboratory accidents continually. In this study, we do not apply the present diagnosis method, checklist, but the safety assessment that is widely used in industry. Then we can find lots of hazard that checklist method could miss. This study will use the 4M and Hazard & Operability to design a new Laboratory safety assessments method.Key Words : 4M, HAZOP, laboratory, risk assessment, checklist.
