10. How Does it Work?
HEAD Set utilises “chemical oxygen”, Potassium Superoxide (KO²), to generate oxygen and allow carbon dioxide (CO²) to be removed. The initial start up phase incorporates a chlorate candle that is activated as the set is donned and the self-test alarm procedure. The wearer exhales through the generators so commencing the generation of oxygen and removal of CO².
