Risk assessment of L-CNG filling stations based on fuzzy comprehensive method

Taking a L-CNG filling station as an example, combining the safety standards of L-CNG industry, 13 major safety influence factors were considered from personnel, equipment, and environment aspects of L-CNG filling station by fuzzy comprehensive evaluation method. The evaluation index and weight sets calculation method were determined, the safety evaluation system of L-CNG filling station was set up, and the evaluation score was obtained by calculation in order to achieve the purpose of risk identification. The analysis of calculation results showed that fuzzy comprehensive method in the application of L-CNG filling station risk assessment was feasible.
