Purpose is an increasing the fire hazard of sealed inhabitated Navy objects through the creation of normobaric hypoxic breathable gas environment. Materials and methods . In the first series of studies, 6 men (22–53 years) daily, for four hours, for 60 days were in the environment of the following content: [O 2 ]=16–17%, [СO 2 ]=0,3–0,8%, N 2 — the rest. In the second series of studies, 6 men (25– 53 years) continuously for 100 days were in the environment of the following content: [O 2 ]=19%, [СO 2 ]=0,3–0,8%, N 2 — the rest. Daily, for 4 hours, men of the second group performed works in the environment with the oxygen content of 16–17%. Results and discussion . Stay in hypoxic environments did not lead to «failure of adaptation” in any of the examined. A gradual increase in resistance to hypoxia was observed due to adaptive changes, greater in individuals who were continuously in hypoxic conditions. Conclusion . The results of the work confirm the perspectiveness of using hypoxic environments in the tested modes to increase the fire safety of the energy-rich inhabited objects of the Navy.
