Oxygen supply is the primary factor in ensuring human survival in confined spaces. Compared with high pressure oxygen bottles, potassium superoxide oxygen board has advantages such as small size, large oxygen storage per unit volume, absorbing carbon dioxide while providing oxygen. However, the release rate of chemical oxygen in a confined space relates to the concentration of carbon dioxide, temperature, humidity and other environmental parameters. To meet human survival needs within the refuge chamber, this paper made experiments on potassium superoxide oxygen production performance factors, including humidity test, carbon dioxide concentrations test, surface spray wet test and so on. Through tests the amount and the rate of oxygen production, and the removal efficiency of carbon dioxide of potassium superoxide in different situations are obtained. And through a human survival experiment, the potassium superoxide oxygen board can satisfy the human body needs is validated. These all provide basis for the establishment of auxiliary oxygen supply facility in the refuge chamber.
