Abstract. The aim of the study – a comparative assessment of the influence on the functional state and performance of people of air environments with different oxygen and carbon dioxide content, used to improve fire safety of inhabited sealed objects.
Materials and methods of research. The study involved 20 male volunteers aged 21-30 years, who spent 4 hours daily during 30 days in normobaric air environments of modified composition.
Research results and their analysis. The main result of the study, in addition to confirming the previously discovered possibility for man to periodically stay and perform work in fire-safe environments, is to define the significant negative impact of the hypercapnic factor, even in concentrations permissible for the premises of hermetic objects, on the physiological reserves of the body and physical performance of a person. When hypoxia and hypercapnia are combined, the undesirable effects of these factors are potentiated, which must necessarily be taken into account when using fire-safe environments in inhabited sealed objects, in which it is necessary to strengthen control over the composition of the gas environment, technical means of ensuring air regeneration and purification, as well as technical means of monitoring the gas environment.
Key words: fireproof air environments, functional state of a person, hypercapnia, hypoxia, inhabited hermetic objects
