First of all, leaders don't pay enough attention to it. Either turn a blind eye, or just shout slogans without implementing human, material and financial resources, without establishing a sound safety responsibility system, and so on.

Secondly, management supervision is not in place. There are no specialized safety technicians or safety administrators, and the safety administrators are not serious, and there is no regulatory supervision. When problems are found, they do not rectify, stay on the surface, fail to find the essential reasons of the problems, and fail to conduct safety education and training for employees.

Finally, it is the problem of other employees. Failure to point out hidden dangers, failure to comply with operating rules or safety regulations, failure to wear protective equipment as required, and arbitrary determination of safety education and training courses, etc.
