In aerospace environments, where preserving human health and performance is vital, the balance between atmospheric pressure and oxygen (O2) concentration becomes a critical life support parameter. An imbalance might necessitate medical-grade 100% O2, which presents a fire risk in confined spaces due to the excess O2 in exhaled air. This paper presents a fire-safe medical oxygen delivery system designed for such environments. Addressing the dual challenge of supplying medical-grade O2 to individuals while concurrently ensuring cabin fire safety, this system effectively reduces excess O2 through chemisorption. The system employs cationic multimetallic cobalt complexes that selectively and stoichiometrically chemisorb O2 from exhaled air, bringing it down to fire-safe levels through reversible thermal cycling. The cobalt complexes were synthesized and characterized using mass spectrometry, vibrational spectroscopy, and thermogravimetric analysis. The results demonstrate that the complexes are thermally stable, absent of undesirable volatile by-products, and have near-stoichiometric O2 absorption and desorption, especially under prolonged heating scenarios. The complex’s thermal conductivity has also been characterized to facilitate sub-second oxygen absorption and desorption as soon as the required temperature is achieved. The findings suggest that this cobalt complex is a potentially reliable solution for oxygen removal. Moreover, its potential within the prognostics and health management (PHM) paradigm for human health and performance (HHP) is highlighted, offering real-time monitoring and intervention capabilities, thus ensuring the safety and well-being of individuals in aerospace environments.
