Abstract:
In chemical industry, hazardous substances and mixtures which exist in different hazardous classes and categories are used and there are many facilities where these dangerous substances are stored, processed, produced, transported, and disposed. It is inevitable for these facilities to undergo both organizational and technical changes throughout their life cycle, and it can lead tu catastrophic accidents if these changes cannot be managed properly. Change management is handled in different process safety management systems and described within the scope of the Regulation on the Prevention of Major Industrial Accidents and Reducing their Effects as the process of evaluating and controlling changes in the design, operation or organization of the facility, or in all its activities, prior to their implementation, to ensure that they do not present a new hazard to employees, the public and the environment and do not increase the risks arising from existing hazards. Within the scope of this thesis, a theoretical methodology which can be applied in organizations with a systematic approach for the change management process has been developed. In order to show how the methodology can be designed and used correctly and effectively within the organization in practice, it has been applied to the change in fuel type in a cement production facility rotary kiln unit. As a result of the field application, it has been determined that the fuel change affects the activities of 80% of the units in the facility, increasing the current risk level and creating a safety vulnerability by revealing a new source of danger. It has increased the level of major accident risks such as explosion, death and injury to a “high” level by affecting the design criteria of critical equipment in the activities of production, maintenance-repair and quality control units. By applying the methodology, measures to reduce risk levels have been determined and it was shown how the change would be implemented without creating a safety vulnerability in the facility.
