There are various hazards and risks in the workflow processes in polyester resin production facilities. The most important of these dangers and risks are; It is related to chemical processes, fire and explosion, equipment malfunctions and storage processes of the products obtained. This study aims to analyze the potential hazards and risks that may be encountered in a polyester resin production facility in the Marmara region, from the arrival of the raw material to the facility, to its processing and storage of the resulting products, with the Functional Resonance Analysis Method (FRAM) and to identify the stages that prevent the processes from being optimized. It has been prepared to make suggestions both for improving workflow processes and reducing risks in the process.
