A systemic approach to hazard analysis and control based on energy function

The hazard analysis and control is one of the most significant issues of the safety management process. The paper proposes a new approach to systemically identify and analyze multi-hazards. The energy function was first studied, summing up the energies involved in production and lives of the national economy with a unified function. Relationships between common production accidents and corresponding energies was presented. In order to take measures in emergency rescue based on energy change, four properties of energy, storability, additivity, transitivity and transformability, were analyzed. The method provide guidance for hazard identification and prevention, and it is proved by guiding the hazard identification of coal mine and carry out effective measures to prevent occurrence of disaster. It indicates that the proposed approach propose a systemic method to analyze multiple hazards and reduce risk of abnormal energy transfer.
