The Establishment and Analysis of Accident Control Model Based onThree-Dimensional Coordinates

Through the analysis of previous theories about the cause of the accident, our study identified the main causes of accidents that are unsafe behaviors of human, unsafe conditions of objects and management factors. And the cause of an accident often is multifactorial not simply due to any one of the above three factors. Unsafe behavior of human, the unsafe condition of object, and management factors are taken as X, Y and Z axis respectively. Keeping the main reason for the accident, interlaced relations among the main reason and the basic laws of security, the accident control model based on three-dimensional coordinates was established. By analyzing the safety factor, accident factor and synthesis factor in the model, the security of the system will be analyzed qualitatively and quantitatively.
