In article metallurgical production as the metallurgy is one of the main sources of technogenic environmental pollution and a working zone is considered. Authors have described the main sources of formation of fine dust by results of which the analysis of fractional structure of the dust particles which are allocated during the operation of the arc melting furnace has been carried out. The submitted data demonstrate that the dust coming to rooms of the shop has the sizes from 3 to 18 microns. The share of mass of particles with sizes less than 10 microns in air of the electrosteel-smelting shop makes from 15%.
