Abstract: Addressing the variability of safety distance calculations in national standards for different fields quantitative risk analysis（QRA）was carried out on a typical hydrogen fuelling station configuration model,and the safety distance and personal risk between the hydrogen fuelling station facilities and the protection targets outside the station were calculated. The cross-validation of standards in many fields（hydrogen energy field and hazardous chemicals field）was realized,and the adaptability difference between hydrogen energy standards and hazardous chemicals standards in hydrogen fuelling stations was revealed,which provided a multi-dimensional reference for the design,construction and risk control of hydrogen fuelling stations.
