산소 발생 폐쇄식 SCBA를 위한 이산화칼륨과 이산화탄소의 반응 정량화 = Quantification of Oxygen Production from Carbon Dioxide Using Potassium Superoxide for Oxygen Generating Closed-Circuit SCBA

다국어 초록 (Multilingual Abstract)

This study demonstrates the use of a chemical containing potassium superoxide (KO2) to convert carbon dioxide (CO2) in air to oxygen (O2). A oxygen generating closed-circuit SCBA(self contained breathing apparatus) removes carbon dioxide by a chemical reaction with potassium dioxide that consumes the carbon dioxide and produces oxygen. Considering the disasters, there is a need to develop strategies to enable the introduction of self-contained self rescuers (SCSR). The potassium superoxide reacts with the wears breath to produce oxygen and absorb carbon dioxide. If the respiration rate of a person is 5 MET(metabolic equivalent), to say 30L/min, at disaster such as fire, mass of potassium superoxide was evaluated as 33.3g with yield and safety factor. Four researchers tested on a laboratory treadmill breathing through SCSRs in a closed circuit, it appears useable for 9 minutes.
