    EN: Purpose. Development of a numerical model to compute the dynamics of atmosphere pollution in workplaces after accidents which results in toxic chemical emission. Methodology. For the numerical simulation of atmosphere pollution in workplaces 3D equation of pollutant dispersion is used. This equation takes into account the convective and dispersion processes of pollutant transport, the rate of toxic chemical emission, position of source emission. For the numerical integration of the governing equation of pollutant dispersion in atmosphere the implicit finite-difference scheme is used. On the basis of the numerical model generic model was developed FORTRAN language was used to develop the generic model. Computational experiments were carried out to calculate the dynamics of pollution after accident emission at ammonia pipeline which is situated at Dnepr River. Findings. The proposed model allow s to simulate the atmosphere pollution in workplaces alter accident emission of toxic chemicals. The model allows quickly obtain the information which can be used for response methods development. Results of numerical experiments are presented. Originality. 3D numerical model was developed allowing to calculate quickly atmosphere pollution after accidents which result in toxic chemical emission. Practical value. The developed model can be used for numerical simulation of air pollution in workplaces after toxic chemicals emissions. It can be used at the stage of PLAS (ПJIAC) development.
