The purpose of the GDR is to formalize the requirements for the a priori selection and development of effective chemisorbents of acidic and / or basic gases, as well as the design of light anti-aerosol and gas-dust respirators, half masks which can be adapted to faces of different sizes and topologies. limits of normalized specific pressure of the half mask on the face. This allowed the design and a priori choice of respirators, taking into account not only their functional purpose (operating conditions), but also the anthropometric features of users' faces and the density of the half-mask to the face during operations. The sorption of H2O, SO2 and NH3 vapor by complex compounds of 3d-metal salts with organic amines deposited on a fibrous carrier has been studied. In order to develop effective chemisorbents of acidic gases for respiratory purposes with the function of visual determination of the moment of "activation" of dynamic absorption capacity due to color change of the material, studies of colorimetric characteristics of "SO2 - tropeolin LLC - H2O" and "SO2 - ethanolamine - H tropeolin LLC" The dynamic activity of existing NSFMs has been increased by adding a small number of prolongator promoters to impregnating solutions. Key words: toxic gases, aerosols, anthropometric dimensions of faces, thermography, obturator, fasteners, nonwoven sorption-filter materials, chemisorbents-ampholytes, sulfur oxide (IV), ammonia, indication of "triggering" of dynamic absorption, absorption capacity.
