RISK ASSESSMENT OF CHEMICALS LEAKAGE IN STORAGE TANK: A CASE STUDY OF FACTORY IN SARABURI PROVINCE
Keywords:Risk Assessment, Chemicals Leakage, Saraburi Province
This article aimed at analyzing and identifying the hazards by assessing the risk of chemical spills of a plant in Saraburi. The data had been correct through the Walk-Through Survey technique and related study, document and research. The fault tree analysis (FTA) and risk assessment had been employed to analyze the data and recommend the guidance of reducing the risk and potential hazards. The results showed that the cause of chemical leakage was from the operation and the damage of the tanks, chemicals and components. In addition, causes from operation can also be divided into 2 sub-causes that can lead to chemical leaks, these can include operational standards and workers’ understanding toward the correct practice of chemicals. Therefore, the preventive and corrective approach for this study consists of 3”E” engineering principles. Firstly, the engineering approach is necessary to assess the risk when changes or related activities occur in the work process. Secondly, the education approach has shown that there is a need to provide training program in enhancing the worker’s understanding towards the hazardous chemical usage. Lastly, the enforcement is defined as a standard of safe operation, including control measures forcing worker to strictly follow.
