Intrinsic safety is the fundamental embodiment of safety production management and prevention, and also the highest realm of safety production management. The term "intrinsic safety" originated from the development of world aerospace technology in 1950s. With the progress of human science and technology and the development of safety theory, this concept is gradually widely accepted.

From the perspective of safety management, intrinsic safety is the change of safety management concept, which is manifested in passively accepting accidents, actively preventing them in advance, eliminating accidents from the source and protecting people's safety. In the past, it was generally believed that accidents in high-risk industries were inevitable, and accidents were accidental.

Intrinsic safety in a narrow sense refers to the safety performance of machinery and equipment itself. When the system fails, machinery and equipment can automatically prevent operational errors or accidents; Even due to human error, the equipment system can be automatically eliminated, switched or safely stopped, thus ensuring the safety of personnel, equipment and property.

Generalized essential safety refers to the safety performance of "man, machine, environment and management" system. Simply put, it is to improve the integrity and make the whole system safe and reliable by optimizing resource allocation.

Intrinsic safety management system is a set of management system with risk pre-control management as the core, people's unsafe behavior as the focus, accident causal chain as the means and continuous improvement as the operation mode.
