Liquefied natural gas (LNG) has the characteristics of low temperature, volatile, flammable and explosive, and its safety issues are being highlighted. The probability and consequences of accident were quantitatively analyzed in combination with the possibility of LNG filling station pump or pipeline spillage. The DEGADIS and LNGFire3 models were used to determine the consequences of the accident. Based on the injury criterion data provided by relevant literature, the article concludes that the personal risk value derived from personal injury level and mortality rate, when compared with personal risk standards of United Kingdom, Netherlands and other countries and institutions, the personal risk value is much lower than the standard limit value, and shows the rationality of establishing 5kW/m2 as the safety distance from critical thermal radiation intensity.
