Evaluation model for safety capacity of chemical industrial park based on acceptable regional risk

The paper defines the Safety Capacity of Chemical Industrial Park (SCCIP) from the perspective of acceptable regional risk. For the purpose of exploring the evaluation model for the SCCIP, a method based on quantitative risk assessment was adopted for evaluating transport risk and to confirm reasonable safety transport capacity of chemical industrial park, and then by combining with the safety storage capacity, a SCCIP evaluation model was put forward. The SCCIP was decided by the smaller one between the largest safety storage capacity and the maximum safety transport capacity, or else, the regional risk of the park will exceed the acceptable level. The developed method was applied to a chemical industrial park in Guangdong province to obtain the maximum safety transport capacity and the SCCIP. The results can be realized in the regional risk control of the park effectively.

Graphical abstractThe relationship between transportation risk and transport capacity was analyzed, and the transportation risk was revised by transport capacity. Regarding the allowable level of transportation risk as control factors, the total number of road transportation vehicles which carry dangerous goods typically such as explosive, inflammable and toxic dangerous goods can be calculated. Then the road safety transport capacity of the park can be calculated, and the safety transport capacity can be obtained. At last, the Safety Capacity of Chemical Industrial Park (SCCIP) was decided by the smaller one between the safety storage capacity and the safety transport capacity based on the acceptable regional risk.Figure optionsDownload full-size imageDownload as PowerPoint slide
