“ In such circumstances, the value of the use of the respiratory protective equipment for protection of workers is difficult to overestimate.
In Western countries have developed respiratory protection program, which was based on the results of measurements of the effectiveness of respirators (conducted both in the laboratory and at workplaces) . These programs are reflected in the sanitary legislation, which have state-wide application. Table 1 presents the documents adopted in several countries over the past decades, which define the requirements for such programs. ”

“ Absent legal regulation of respirators selection and respiratory organ protective programms, lack of training programms and tutorals based on legislation requirements can be potentially harmful for workers' health. ”

“ The expected value of the protection factors of respirators, which in developed countries are used as criteria for the admissibility of application of RPD particular design (to protecl workers in known in workplace conditions) (tab. 5) take into account such reduction. Mentioned in this table, the expected protection factors show that for reliable protection of operating at high air pollution need respirators with forced air supply under the mask. The U.S. share of workers that make use of such respirators, exceeds 10% [38] . ”
