① Basic theories of safety science and technology, such as catastrophe theory, disaster physics, disaster chemistry, safety mathematics, etc.
② Application theory of safety science and technology: such as safety system engineering, safety ergonomics, safety psychology, safety economics, safety law, etc.
③ Professional technology: including safety engineering, fire and explosion prevention engineering, electrical safety engineering, traffic safety engineering) and occupational health engineering (dust removal, anti-virus, personal protection, etc. ), safety management engineering, etc. Safety science and technology span the fields of natural science and social science, and its development in recent ten years directly affects the development of economy and society. With the comprehensive establishment of safety science, in the 2 1 century, people will have a deeper understanding of the nature of safety and its changing law, guide people's labor and production practice activities with the theory of safety science, protect the safety and health of workers and the public, develop production, increase economy, create material civilization and spiritual civilization, and promote social progress.
Safety science is not only an important and indispensable productive force, but also the driving force and basic guarantee condition for production and social development. Industrial accidents and disasters have caused great harm to human safety and health, and have had a social impact that cannot be ignored. Mainly manifested in: First, labor disputes caused by occupational hazards such as industrial production accidents have increased, and contradictions are easy to be sharp. Especially after China achieved a well-off living standard in 2 1 century, people's demand for production and living safety has been increasing. Improper handling of bad working conditions that endanger personal safety and health will affect social stability. Second, people regard safe, hygienic and comfortable working conditions as an important criterion for career choice. If they develop in production mode, their production development will be seriously affected, because they can't recruit high-quality workers in industries with frequent major accidents, which will further affect the balance, sustainability and development of the industries. Third, industrial accidents and disasters not only cause huge economic losses and ecological environment damage, but also cause social instability, and also cause unbearable psychological burden to people.
The root cause of serious accidents and occupational diseases in China lies in the backward level of safety science and technology, and the safety management and engineering equipment can not meet the needs of safe production development. Safety in production is related to the rise and fall of enterprises, to the safety of the people, and to the national economy and people's livelihood. Therefore, it is necessary to ensure the synchronous planning and development of safety science and technology and national economic construction. At the same time, safety technology is the foundation and guarantee of safe production. Safety science reveals the essence and law of safety, protects productivity through safety engineering technology and promotes safe and civilized production. The development of safety science and technology is unified with the development of national economy and society. Facts have proved that safety science and technology not only affects the development of productivity and the improvement of labor productivity, but also affects the growth of national economy. In the 2 1 century long-term science and technology development plan of China, the contents and indicators for developing safety science and technology have been specially formulated.
2 1 century will be the era of rapid development of safety science, and 2 1 century will be the spring of safety science.
