Abstract: Taking the natural gas processing station of a gas production plant as an example, the operation activities were sorted out according to three levels covering operating items, operating tasks and operating steps based on the mainline of operating units, process flows and equipment. Positive hazard factor identification method was adopted to identify risk factors. Combining with the analysis on the characteristics of gas production process, the sample table of accident consequence of gas production plant was formed. And the prevention and control level was determined according to the risk level. Thus the standardization, accuracy and rationality of the analysis results were realized| risk and responsibility classification were implemented. Meanwhile, this paper discusses the guiding significance of the analysis results on site safety management and clarifies the application methods. The application barriers were broken through. These help to improve the level of site safety management effectively.

Key words: natural gas extraction, production activities, risk classification prevention and control, process and method
