To describe the safety rules of various industrial process data and explore the characteristics of unsafe behaviour, the association rules of unsafe behaviour based on pan-scene were proposed in this study. First, based on the scene data theory, unsafe behaviour was described by eight dimensions (time, location, behavioural individual, unsafe action, behavioural attribute, behavioural trace, professional category and risk level) to achieve scene data description and structural transformation. Second, the Apriori algorithm was used to explore the distribution rules of unsafe behaviour dimensions and the interaction between different dimensions from two perspectives: single-dimensional statistical analysis and multidimensional association rule mining. Finally, through SPSS Modeler software, an empirical analysis of pan-scene data for subway construction was conducted, and the association rules between type of work, construction stage, working time and unsafe action were identified. Some strong association rules were produced by the association analysis. For example, during the 13:00–17:00 of the excavation floor stage, the most frequent unsafe action of machine operators is the irregular binding of lifting objects. This result could explain why some unsafe actions are prone to occur in different construction stages and working times for workers of different types, which can be controlled and managed in a targeted manner, thus reducing the possibility of accidents.

In recent years, China has accelerated the construction of work safety laws, reformed the national safety supervision system, and gradually upgraded its safety requirements and standards. Since 2003, work safety standardization has been implemented to assist enterprises in identifying the main responsibility of work safety, and strengthening the foundation of work safety. The two key objectives of this paper are the following: (a) to analyze the current status of work safety standardization in China, and (b) to introduce how Beijing uses local standards to promote work safety standardization. First, this paper reviewed the current situation of work safety standardization regarding the policy background, system construction, and safety promotion. Second, the “ Hundred local standards” campaign in Beijing was analyzed to further explain work safety standardization, which includes the project background, preparation process, and framework content. The hundred local standards cover key enterprises and institutions in various industries and provide a strong standard basis for strengthening government supervision and enterprise safety management. In addition, it is worth provincial regions learning to promote work safety standardization toward a more standardized and scientific direction. This paper can promote cooperation and exchange on work safety among regions to promote work safety standardization.
