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 OccupationalHealth and Safety Law companies are categorized in three sections as LessRisky, Risky, and High Risky Companies. Based on this law, a regulation called“Occupational Health and Safety Regulation” has become operative and all of thecompanies compassed by this regulation are forced to prepare a risk assessmentreport in order to provide occupational health and safety, and increase theiroccupational health and safety levels. In the literature, there are about twohundreds of risk assessment methodologies. Among these methodologies, themostly used ones are 5 by 5 L-type matrix method, Fine Kinney Method, andHazard and Operability Analysis (HAZOP) which is proposed for the analysis ofthe risks in the chemical industry. These methods include strict lines and arenot reflecting the practical issues of the real world applications. For thisreason, these methods are to be adopted by the use of fuzzy logic. In thisstudy, risk assessment methods used in the risk rating are evaluated and fuzzyapproaches are proposed to provide more efficient and realistic results.
