How can we ensure our personal safety and the safety of experimental equipment during the training period?

If it is a dangerous training, it is necessary to wear safety protection and check the equipment before entering the laboratory to ensure personal safety; Every laboratory has different safety regulations, which need to be strictly enforced. The recent explosion in Nanjing University of Aeronautics and Astronautics laboratory caused death and injury is a painful lesson.

the laboratory is the place where experiments are conducted. Laboratory is the cradle of science, the base of scientific research and the source of scientific and technological development, which plays a very important role in scientific and technological development.

Laboratories can be divided into three categories according to their ownership: the first category is those affiliated to or managed by universities; The second kind of laboratories belong to national institutions, and some are even international institutions; The third kind of laboratory directly belongs to the industrial enterprise department and serves the development and research of industrial technology.
