The article is devoted to the issue of improving the environmental safety of the construction industry by improving the systems of decreasing dust emissions by aspiration systems using a comprehensive dispersive analysis. There was proposed to develop a promising approach using the criteria of hydrodynamic similarity in the output functions of the complex analysis of variance to increase the efficiency of aspiration decreasing dust systems in this article. The article focuses on the environmental problems of building construction industry. The volume and different kinds of mixtures of bulk building materials and cements to produce various types of concrete construction units and materials are in stable demand every year. It means that average amount of dust particles substances in emissions at the manufacturing production of building materials every year too. The results of studies show that a significant content of fine particles, for example, 10 microns or less is concern in dust emissions systems of aspiration at the building construction enterprises. One of ways to increase the environmental safety is reduction of dust emissions to design dust capturing devices that have low values of slippage out from aspirations’ decreasing dust systems. It was achieved by special complex integrated analysis’ method of variance dust that applies hydrodynamic sedimentation of particles. It is the way to obtain distribution of dimensionless numerical complexes — the hydrodynamic similarity criteria for the dust studied samples. There presented results of experiment that gave more reliable approach to get evaluations of the complex analysis of particles sedimentation velocity’s distributions.

The article presents the results of studies of the surface characteristics of textile materials used for personal protective equipment and in construction projects, taking into account the climatic conditions of their operation. The features of their optical and color properties in the open industrial area in the cold period, which form the elements of General industrial safety, are revealed. The influence of low temperature and humidity on the structure and surface properties of materials of the different fibrous composition is experimentally established. This leads to the correction of optical parameters of various objects on construction and industrial sites, determining the conditions of sufficient or limited visibility. The results are adapted to solving the problems of designing environmental spaces of construction projects and the development of innovations in textile materials science and means of individual safety in the industry.
