Professor Zhao Jinsong from the Department of Chemical Engineering at Tsinghua University raised a question at an academic forum: Why are major accidents in hazardous chemicals companies impossible to prevent, sparking discussions on the causes of such accidents. According to the study on the causes of accidents in large hazardous chemicals enterprises (available on CNKI or Baidu), the primary causative factors include: 1. Human reliability, 2. Equipment integrity, 3. Process materials, 4. Management procedures. If you were to rank them based on the frequency of occurrence as a cause of accidents (from highest to lowest), how would you do it? (Double rewards for excellent comments) ------------------------------------------------------------------------------------------------- According to data as of October 7, factors related to human reliability accounted for approximately 58.82% of the total, factors related to equipment integrity accounted for about 23.53%, factors related to process and materials accounted for around 11.76%, and factors related to management procedures accounted for approximately 5.88%. Factor proportion (%) Human reliability factor: 58.82, Equipment integrity factor: 23.53, Process and materials factor: 11.76, Management procedures factor: 5.88
1. Equipment integrity 2. Human factor reliability 3. Management procedures 4. Process materials
Human, machine, materials, methods, environment, and measurement – in terms of importance, these six elements can be used to analyze any issue. Human beings are always the key factor; their role comes first at all times. Machine refers to equipment factors, materials relate to the properties of those materials, methods involve process management, and measurement refers to the techniques used for assessment. Environment is another important aspect. In summary, it all boils down to human, machine, and environment management measures. To sum it up, there are these four points: 1. Unsafe human behavior; 2. Unsafe conditions of the machinery; 3. Unfavorable environmental factors; 4. Inadequate management measures

The frequency of causes for accidents, in order from highest to lowest, should be: 1. Human factor reliability: Human errors are one of the main reasons for accidents in chemical manufacturing companies. For example, issues such as human error, carelessness, and insufficient technical skills can all lead to accidents. 2. Equipment integrity: Equipment problems are also a significant factor contributing to accidents in hazardous chemicals enterprises. For example, equipment aging, failures, and improper maintenance can all lead to accidents. 3. Management procedures: Unreasonable or imperfect management procedures are also a major cause of accidents in hazardous chemicals enterprises. For example, inadequate safety management systems and insufficient measures for civilized construction can all increase the likelihood of accidents. 4. Process materials: There are relatively few issues with process materials, but they can still lead to accidents. For example, improper selection of materials and inadequate control of reaction conditions can both lead to accidents. Note: The above sorting is merely one possible arrangement based on the frequency of causes; the actual arrangement will need to be determined through actual investigations and data analysis. .

The human factor is number one. Because no matter what the process, equipment, or raw materials are, it is people who design, operate, and manage them.

From the perspective of regulatory authorities, none of them are hassle-free (tied for first place)； From the boss’s perspective, all of these are issues that can be resolved without investing any money (primary management issues) ； From the perspective of a safety manager, everyone, from top to bottom, is a bunch of idiots dancing around (it’s mainly due to human error) ； From the perspective of the workers, the site is full of broken items (equipment integrity is of primary importance) ； From the designers’ perspective, as long as it does not involve hazardous processes or chemicals that are under strict regulation, the answer is simply: good.
