Research of Safety Management of Large-Scale Petrochemical Construction Projects Based on Safety Chain Model

This paper briefly introduces the features of large-scale petrochemical construction projects,safety management status and development at home and abroad safety chain theory.In order to strengthen the safety management of such projects,it presents a new safety chain model which integrates safety factors with process systems according to the system theory and the concept of people oriented.This model can accurately locate the safety factors of the construction projects from the aspects of people,environment,information,construction facilities,operating facilities,technology and management,and the process systems containing pro-action,prevention,preparation,response,and recovery which reflect the life cycle of projects,some targeted safety measures are then made.The proposed model deepens the safety management of construction projects and provides an analysis tool for safety management from micro and macro levels.Finally,the model was applied to analyze the safety management measures and methods for Ningxia Petrochemical Company′s 5 million tons/year refinery expansion project.The result shows that the level of project safety management has been significantly improved.
