Application of causal analysis to the safety management of urban water environment treatment project

There are a large number of hazard sources in the construction site, and each hazard source may cause a safety accident. Therefore, timely and accurate identification of hazard sources becomes a necessary for safety management at the construction site. Along with the characteristics of the construction site of the Maozhou River Rehabilitation Project, from the four aspects of management, people, environment and objects, the causal analysis method is used to analyze the hazard sources of safety accident at the construction site. According to the analyzed hazard sources, the total safety management of the project was realized through the PDCA cycle.
