A: In a human-centered system, in the process of taking action to realize a certain intention, in the time-space sequence related to energy, an event that suddenly happens contrary to people's hopes and will is called an accident. Accidents include casualties, non-casualties and near misses. 19. What are the characteristics of the accident? A: The characteristics of the accident mainly include four aspects: 1. Accidents are causal, conditional and regular. The relationship between two phenomena, such as insufficient education, management defects and unsafe factors in the material environment, is the basis of a phenomenon and will lead to accidents. 2. Accidents are accidental, inevitable and preventable. Accidents are essentially random events that may or may not occur under certain conditions, and appear as time goes on. When unsafe factors and incidents are fully assembled, accidents will inevitably occur; Only by taking preventive measures can accidents be prevented. 3. Accidents are potential, repeatable and predictable. The potential of accidents lies in unsafe hidden dangers, and safety work is to find the potential of accidents, eradicate their hidden dangers and prevent them from appearing again. With people as the main body, accidents in natural objects can be predicted and the reliability of prediction can be continuously improved. This is why people should investigate and analyze the accident and deal with it according to the principle of "three-no pass". 4. The accident is precursor, explosive and fire-fighting. It is an important task of our safety work to rescue quickly, put out in time and actively prevent accidents. 20. What are the four conditions of the accident? Answer: Coal mine production is an activity to organize employees to use the required materials, machinery, equipment, facilities and other material conditions under certain environmental conditions through management. In the production process under certain environmental conditions, management defects and unsafe conditions of materials form hidden dangers of accidents. If people's unsafe behavior touches the hidden danger of accidents, injury accidents will occur. The four factors of accident formation can be expressed by the set formula: accident = {unsafe environment, management defect, unsafe state of things, unsafe behavior of people}. Among the four elements of "people, management, things and environment", the human factor is dominant, the management factor is the key, the material factor is the foundation and the environmental factor is the condition. People, management, things and environment are interrelated. 2 1. What are the five elements of an accident? Answer: Looking at any accident, it includes five elements, namely: 1, injury (loss); 2.
