Broad concept of safety culture is derived from the definition of culture according to the dictionary, that is, safety culture
is the sum of security-related material and spiritual wealth1 [1].Typical theory is the theory of safety culture of four levels
[2-5], what is considered that safety culture is the system of physical culture, institutional culture, behavior culture and
spiritual culture. Two industrial standards [6-7], Directives for Developing Enterprise Safety Culture and Assessment
Standards of Enterprise Safety Culture Developing, were enacted by the State Administration of Work Safety in 2008. Both
of them are defined safety culture as “the sharing of safety values, attitudes, ethics and code of conduct” in a certain
organization, which will provide the working direction for the safety culture construction. However, the required content of
these two standards are far broader than that of it is in fact, and they shows a consistency only in some degree, that is, the
meaning of safety culture are still more broadly. In addition, some literatures have showed that safety culture is a collection
of safety problems [8-9], it apparently also broaden the definition of safety culture. So, there are two viewpoints can be
summarized in general mentioned above, one can be read the knowledge of safety culture”, the other can be understood as
“the aspects of the safety work”, and the first viewpoint could be contained by the second one. Thus, there would be only
one meaning of safety culture, namely “the aspects of the safety work”. So the problem left is what safety culture contains is
too broad, and no clear boundary, which made it difficult to grasp in the process of safety culture construction.
Different from the broad concept, the narrow definition of safety culture lays emphasis on some specific level, such as
“spirit” or “behavior” level. It has been widely thought that safety culture cans influent the spirit level, and it is the
guidelines to decide behavior. Also some scholars agree that safety culture is basic assumption [10], it can affect the attitude
and behavior of staffs [11], and it is the belief and value about health and safety problems [12]. Although concentration on
some level, the research still do not point out what the safety culture is. That is because the terms, such as basic tacit,
attitude, and belief and values and so on, seem too abstract to use, and it is difficult to reflect what the safety culture
construction should contain and how to do it. Therefore, whether the broad safety culture or narrow, defining the concept of
safety culture either too broad or too abstract, that makes the safety culture construction too difficult to grasp in actual.
As a result, we propose that safety culture is the sum of a series of concepts, that is, safety culture is the ideas of safety
management. This definition is obtained through the analysis the narrow definition above, and it also can be seen as the
limited result.Therefore, it may be called a limited definition of safety culture. Safety culture is the most important part of
enterprise safety management system. As the most fundamental means, improving the quality and operation mode of safety
management level could prevent major accidents, reduce accident rates and improve safety performance [13]. So safety
culture has close relations to accident rate, affecting the level of accident rate
