The basic characteristics of production safety accidents include five aspects:
1. Particularity of the accident subject: it is limited to the accidents that occur in the production and business operation activities of the production and business operation units. Units engaged in production and business activities mainly include companies, enterprises, partners, self-employed and other production and business units in the industrial, mining and commercial fields.
2. Extensibility of accident area: The geographical scope of production safety accidents is not fixed, but limited.
3. Destructiveness of accidents: production safety accidents have caused certain damage to personnel or production and business units, resulting in casualties (including acute poisoning) or direct economic losses of production and business units, affecting the normal development of production and business activities and causing serious impact.
4. Suddenness of accidents: Production safety accidents occur suddenly in a short time, which is different from other damage events under the long-term influence of some hazardous factors, such as occupational diseases.
5. Accident negligence: production safety accidents are mainly accidents caused by human negligence, which are essentially different from disasters caused by force majeure such as floods and mudslides, such as production safety accidents caused by illegal operations and risky operations;
The occurrence of production safety accidents caused by bad working environment, hidden dangers of equipment, etc. should also be classified as negligence, that is, the person in charge of the production and business operation unit has negligence in the safety production management of the unit, failed to immediately correct and eliminate the bad operation factors, and allowed the bad factors to continue to exist.
