What are the basic theories of modern safety management

Modern safety management has a lot of content, summarized in the following five aspects: management of ideas, talent management, method management, institutional management and modernization of management tools. Which specifically covers the safety and accidents, system safety management theory, accident causation theory, accident prevention principles and other parts of the content.

The relationship between safety and accidents: first of all, we need to understand the social attributes of safety and natural attributes, natural attributes belong to the basic needs of human survival and development, and human physiology and psychology are inseparable; social attributes refers to a series of organized social activities carried out by human beings, safety as an important symbol of the realization of the stability and progress of society, human activities have a positive role in promoting, but also have a direct destructive role. Safety has a positive and destructive effect on human activities. Therefore, safety and accidents have a unity of opposites, interdependent relationship.

System safety management: It is intended to apply the principles of system safety management and system safety engineering to realize the source of danger and reduce its harmfulness, so as to make the system achieve the optimal degree of safety within the specified performance, time and cost. Its basic principle is that it changes the traditional concept of focusing only on the unsafe behavior of the operator, but also considers the failure of the hardware in the cause of the accident, and ensures safety by increasing the complexity of the system.

For things that can go wrong or environmental factors may be a source of danger, the chance of causing harm or loss can be calculated in terms of probability. Sources of danger and hazards are endless and cannot be eradicated, only the danger from existing sources can be reduced.

According to the universal law of frequency and severity of accidents, there are generally fewer accidents with serious injuries, more accidents with minor injuries than with serious injuries, and the greatest number of accidents without injuries. A person has experienced hundreds of accidents that did not bring harm before they were harmed. Countless unsafe behaviors and unsafe conditions have been repeated before each accident. Behind every minor and no-harm injury and causing major accidents and injuries have the same factors, all of which are unsafe human behaviors and states. Therefore, to avoid injuries and fatalities should be taken as early as possible.
