This paper proposes Grey relation analysis approach using Grey system theory to analyze the influence factors for catastrophic accident in chemical plants. The examples from explosion, fire accident and leakage, are used in the development of relation analysis model of catastrophic accident factors based on Grey relation analysis. The future behavior index and accident influence factors are used for system safety analysis. The dynamic quantitative analysis is proposed to confirm the dominant main and sub factors that influence system safety. The proposed system will enable us to comprehend accidents and to support the decision-making process for system safety. After implementing this method to accident database, the priority of the accident factors can be determined and used for safety management in the chemical plants.
