Abstract: Urban refineries are formed gradually in the process of urban development and such refineries have a negative impact on the safety of the surrounding living environment, which must be studied and solved. Double prevention mechanisms is an effective measure to curb serious and major accidents. This paper proposes the key points for the construction of the double prevention mechanisms in urban refineries. It includes combining with the acceptable risk criteria, and using the criteria to determine whether the safety protection distance and protection measures are in place; matching the risk ranking and control classification with each other to ensure the implementation of risk grading management and control; combining the risk identification results with the hidden danger investigation to solve the current situation of independent operation of both; promoting the construction of information-based management of the double prevention mechanisms, and the whole construction contains 6 logical layers of information platform architecture.
