While the trade volume of the metal sector is expanding day by day, the number of welding workshops engaged in metal production and processing is also increasing. The metal sector and sub-industry branches are in the very dangerous class in terms of Occupational Health and Safety (OHS). In order for the work to be productive in these lines of business, it is necessary to identify the hazards and make a risk assessment. The fact that the risks have different structures has led to the development of various risk assessment methods. In this study, the risk factors identified in a metal production-processing welding workshop were analyzed with 5 different risk assessment methods, and then the results of these assessment methods were compared. During the risk assessment phase, the workplace and workplace hazards were kept constant and it was investigated whether the data of assessment criteria such as frequency and discoverability in the analysis process of risk assessment methods have an effect on the results obtained with the selected risk assessment methods. Fine Kinney Method, 5x5 L-Type Matrix, Failure Modes and Effects Analysis (FMEA), Fault Tree Analysis (FTA) and What If Analysis methods were used as Risk Assessment methods in this workplace where 30 sources of danger were identified. It has been determined that risk assessment methods give different results for the same hazards and risks. Among the different risk analysis methods in this study, the method of analysis that has the highest number of first-degree risk priority, that is, the risks that need to be taken quickly, is the Failure Modes and Effect Analysis.
