This article describes the method of dust emission suppression at a construction site. The results of the effectiveness of the developed equipment, fog formation gun, were obtained in the course of full-scale measurements in the course of stone installation works at the construction site in Rostov-on-don. The assessment of the air dustiness of the builder workplace and the degree of impact of the fog formation gun were attended with the statistical dependence of the number of dust particles PM2.5-PM10 . During the analysis, the following factors were studied: the location of the workplace at the construction site, the relative humidity and temperature. During the study, the following conditions were met: the premises were closed; the study was carried out in the process of performing stone installation works. The results of the experiment showed the effectiveness of the fog gun.
