This paper describes a method to calculate risks generated by liquefied natural gas (LNG) filling stations for road trucks. An increasing number of these stations are operational in the Netherlands and they require activities such as transfer, storage, saturation and supply of LNG. Under the Dutch legislative context, facilities that handle or store large amounts of hazardous substances must carry out a quantitative risk analysis (QRA) for land-use planning purposes. The outcomes of the QRA determine the kinds of activities that are acceptable in the surroundings of the facility. The method defines which release scenarios and frequencies to use and how consequences of release scenarios must be calculated. Outcomes are presented for a generic station and some alternative designs for which calculated safety distances are in the range of 66-140 meter.
