Abstract
The article presents the results of workplaces certification on the Joint-Stock Company "Diversified manufacturing company "KRZ" according to working conditions. The company deals with computer-aided production of rolled- roofing materials. Content of chemical substances and aerosols of fibrogenic action in the air of working zones, as well as industrial noise levels, artificial light, microclimate, workflow severity and intensity in the shops of rolled-roofing and waterproofing materials and paper and paperboard production of the enterprise have been estimated. According to the results of hygienic investigation most of working environment was harmful (class 3 1-2 degrees). Workers of major technical professions such as operators of dipping units, turbomixers operators, bitumen unwatering operators, papermaking sorters, cardboard machine (CBM) operators, CBM couchers, CBM machinists, CBM drying operators were exposed to a complex of environment factors, the most unfavorable of which are chemical, microclimate and severity of labor process. Our recommendations for improving working conditions are to introduce technological measures: mechanization of beating-engines and thickeners cleaning, talcose emulsification, modernization of winding and wet-tissue packaging machines. Space-planning decision is isolation of automated production lines for rolled roofing material. The plan for sanitary-hygienic measures includes hoods installation on the dry end of the production line, use of the hydrodedusting system, equipment of local artificial lighting according to the workplace sanitary standards, organization of work and rest schedule with double shift work and two weekends. As mandatory respiratory protective equipment - respirators SHB-1 "Lepestok™-5" are recommended; organs of vision protective equipment - goggles; skin - hand protection water-repellant cream, hand cleansing paste, silicone hand cream; work clothing - bitumen protection cotton suit with coated fabric laps; canvas gloves.
