FIELD: individual facilities for protecting person's respiratory organs. SUBSTANCE: protective means has flexible filtering absorbing system of nonwoven material, which is mixture of thermally stable polyimide active char coal fiber and active chemosorption fiber. Nonwoven material may be also made in the form of successive layers, wherein outer layers are made from thermally stable polyimide fibers and active char coal layer and active chemsorption layer are arranged between outer layers. Protective means allows worker to operate under elevated temperatures of environment containing gases, vapors, aerosols hazardous for worker's health, as well as substances chemically and biologically hazardous for worker's respiratory organs. EFFECT: increased efficiency and simplified structure of protective means. 4 cl, 2 dwg
