This guideline presents a computation method to estimate the dispersion of emissions by accidental releases on the basis of the Gaussian dispersion equation; this method is part of the safety study according to the administrative regulation for the ordinance on industrial accidents. Thereby the meteorological input parameters have been selected such that a mean dispersion situation as well as the worst possible dispersion within the frame of this model are covered. This means that the computation method must not be used for calculating acute industrial accidents of for reconstructing suspected ones.*Specifications on the type and the spatial as well as temporal course of the pollutant release, danger areas, damages and possible effects are not dealt with in this guideline.
