Brief description

This guideline presents a calculation method for estimating the dispersion of accidental releases as part of the safety analysis in accordance with the Administrative Regulation on the Major Accidents Ordinance on the basis of the Gaussian dispersion formulae. The meteorological input parameters were selected in such a way that an average and the most unfavorable dispersion situation within the framework of this model are recorded. This means that the calculation method may not be used to treat actual incidents or to reconstruct suspected incidents.* Information on the type, spatial and temporal progression of pollutant release, hazard areas, damage and effects are not part of this guideline.
