emergency rescue circumstances. For this purpose, gas masks have to be used and its use were increased, but actually their function have been insufficient in real situations. Decreasing with increasing temperature in chemical reaction of KO_2 with CO_2 and humidity, the method of reaction acceleration and formation of hazard materials after their reaction in self oxygen generating mask have to be investigated. A reagent decreasing the temperature in reaction cell was introduced because heat was occurred in there by the reaction of KO_2 with CO_2and water. Also an accelerating agent was considered to obtain lots of O_2 during short time. The probability of basic mist formation after O_2 generating reaction was evaluated in chemical view point. It was observed that the phenomenon in which the temperature in reaction cell decreased by potassium nitrate as coolant as well as a lot of O_2 could be obtained by sodium hydrogen carbonate in short time. Also expected basic mist does not observed from this O_2 generating reaction. The temperature could be decreased by potassium nitrate as endothermic agent, also the reaction was stably accelerated by sodium hydrogen carbonate as adduct and the hazard material as basic mist to human body was not detect.
