Fuzzy Approaches to the Risk Assesment Methods for the Occupational Health and Safety

Abstract

Turkey’s “Occupational Health and Safety Law” numbered as 6331 has been published in June 2012. According to the Occupational Health and Safety Law companies are categorized in three sections as Less Risky, Risky, and High Risky Companies. Based on this law, a regulation called “Occupational Health and Safety Regulation” has become operative and all of the companies compassed by this regulation are forced to prepare a risk assessment report in order to provide occupational health and safety, and increase their occupational health and safety levels. In the literature, there are about two hundreds of risk assessment methodologies. Among these methodologies, the mostly used ones are 5 by 5 L-type matrix method, Fine Kinney Method, and Hazard and Operability Analysis (HAZOP) which is proposed for the analysis of the risks in the chemical industry. These methods include strict lines and are not reflecting the practical issues of the real world applications. For this reason, these methods are to be adopted by the use of fuzzy logic. In this study, risk assessment methods used in the risk rating are evaluated and fuzzy approaches are proposed to provide more efficient and realistic results.
