Evaluation of Risks by L-Type (5x5) Matrix Method in an Ore Concentration Structure%253A A Case Study

Workplaces are places with a dynamic structure. This situation often leaves employees vulnerable to certain risks. Occupational accidents in the workplace are caused by various reasons such as production methods, human presence and environmental factors. For this reason, the most important element of a sustainable production is to ensure occupational health and safety. Creating a safe working environment in a workplace can only be achieved with a risk assessment prepared with the participation of people with high levels of competence (employer%252Fdeputy, occupational safety specialist, workplace doctor and other persons). Risk assessment begins during the establishment or design process of a workplace. This process consists of various processes such as identifying hazards, identifying and analyzing risks, deciding on risk control measures, and documentation. The most important point to be considered while making a risk assessment is to determine the most appropriate risk assessment method for the exploitation or plant. Factors such as production method, sector, type of risks and interaction with each other are among the main determining factors in determining the hazard class of workplaces. In this study, risks were evaluated in an ore beneficiation plant. The ore beneficiation facility is an area where the conversion of the ore extracted from the underground into the final product takes place. The work area is located in a very hazard class. Considering these issues, risks were evaluated using the L Type Matrix (5x5) method in the study. The L-Type Matrix method is more advantageous than many methods in that it is easy to understand and can be applied to many processes. A total of 72 risks were identified in the study. These risks are scored%253B 18 low risk, 30 medium risk, 24 high risk were identified. Considering the result of the study, some solution suggestions are presented in order to provide a safer working environment in the conclusion and suggestions section of the study
