Risk assessment and identification the accident points in one of the highway construction sites using the Failure Mode and Effects Analysis method and drawing Safety contour maps

Background: Frequent and continuous occupational safety has been a worrying issue in terms of human, economic and legal issues. Comparing the safety efforts of companies with high and low incidents is related to the type of industry, its breadth and its geographical location. Risk assessment is a logical method for risk assessment that specifies the risks and their potential implications for individuals, materials, equipment and the environment. The aim of this study was to identify both risk and risk assessment in a highway construction site using the FMEA method and drawing safety contour maps with ArcGIS V.10.2 software.Materials and methods: This paper was implemented in 9 general steps as follows: 1. Demographic data review 2. Identification of the risk of people 3. Risk causes 4. Risk effects 5. Determination of severity, occurrence and detection 6. Risk rating 7. Controls 8. Enter the coordinates and RPNs of occupations in each location in the ArcGIS 9. Drawing the safety contour maps into ArcGIS V.10.2. The mean and standard deviation of the data were measured using SPSS V.22 software.Results: In this site, 62.97% of the units had a moderate risk and other ones, had a low risk (37.03%). The highest RPN were for light machines with a value of 42.91, asphalt rollers with the value of 41.3 respectively and the lowest RPN was calculated in the laboratory and then the water supply plant.Conclusion: Most of the site units had a moderate risk and it is expected that the risk of units will be decreased and minimized by applying the proposed items
