Abstract

Purpose. Increase security life on workers places with increased radiation heat. Method. Construction thermal fields and establishment depending on changes infrared radiation from location workers locations, form source radiation and spectrum sources radiation. Results. On basis conducted research on thermal plot society with limited liability ?Sanitary engineering ZAZ? with application high temperature installations for production product: Position ТHF, tunnels furnace, camera furnace, furnace cooking glass weight, furnace quenching, warm-up and holiday set, that labor places operators and other categories employees exposed excess thermal infrared radiation with intensity from 150 to 2900 Vt/m2 in short wave λ=1,4-2,5 mkm, so and longest wave range λ=3,7-14,0 mkm, that causes deterioration health and violation health employed and requires development special measures by reduction their harmful influence. Set, that existing devices domestic and foreign production not allow explore terms labors on workers places hot productions of-for significant range thermal radiation from 50 to 24000 Vt/m2, that makes significant error in measurement. Installed regularities changes reflectivity ability from form material and length spectrum radiation. Scientific novelty. On based conducted research intensity excess thermal radiation on labor places hot productions and established, at this, temperature heat surfaces set distribution maximum length waves infrared radiation, confirmed by law Golitsyn-Vin. Proposed express-method evaluation reflectivity ability materials, which allows operatively receive information on initial stage research and development protective funds from infrared radiation. Practical meaningfulness. Improved stand for of research reflectivity and transmissive ability materials with given variable angle fall radiation, state surface and its polarization ability, error, at this, not exceeds 5?7 %. Proposed new approach in creation effective protective funds with Given spectral component infrared radiation.
