Abstract
The results of the analysis of existing approaches to solving the problem of propagation of impurities in the air and the prediction of residual contamination of the air of working areas. Presented by the rationale for selecting the method of "coarse particles" for the numerical experiment. We describe the nature and advantages of the method as applied to the calculation of the spread of contaminants. An algorithm for prediction of sanitary efficiency of the trapping of pollutants.
