FIELD: chemistry.
SUBSTANCE: invention relates to compositions of chemical substances used in self-contained breathing apparatus operating on fixed oxygen, and can be used in production of air regeneration products based on potassium superperoxide. The air regeneration product has the following composition (wt %): potassium superperoxide - (90-98); potassium (IV) ferrate - (2-10).
EFFECT: when used, the self-contained breathing apparatus equipped with the disclosed regenerative product has higher temperature of circulating air during inhalation and considerably lower aerodynamic resistance to breathing of the user.
