Abstract
A basic list of polluting components released into the air zone of production sites of the metalwork and welding division of the VASO facility has been established, with differentiation into 6 sectors with emission generators. It was found that the greatest contribution to the overall background of polluting components accumulation in terms of quantity is made by 2 sites: sandblasting and gas welding, the sector of plasma cutting and alloys based on it is distinguished by the variety of components allocated. Quantitative estimation of gross and maximum one-time emissions has been implemented. Analytical assessment recorded by: inorganic dust with SiO2 over 70 %, fixed at sandblasting sector, a slight excess of MPC and sector gas welding in the NO2 limit value with the MPC.
