An Occupatıonal Safety Fuzzy Rısk Analysıs: an Applıcatıon in a Buıldıng Constructıon Sites

Abstract

The employers should be creating a safe workplace environment in working life. A safe working environment is one where risks are eliminated or at an acceptable level. Building works is one of the sectors with the highest number of occupational accidents. In this study, fuzzy logic is proposed to determine the risk levels with linguistic words in risk analysis, which is the most important step of the occupational health management system in the building works. In the fuzzy risk assessment, the fuzzy model was first proposed and then the risk numbers were calculated. In the research, a risk assessment was carried out using fuzzy logic method in a construction site consisting of ten blocks and twelve-storey apartments belonging to a building company. In the fuzzy risk assessment, the fuzzification of the input data, the creation of the member functions of the input and output values, and the fuzzification processes were done with the help of the fuzzy logic toolbox of the MATLAB software program. The results showed that fuzzy risk analysis is effective and credible for creating a safe building site.
