Chemical Oxygen Generator - Uses

Uses

Chemical oxygen generators are used in aircraft, breathing apparatus for firefighters and mine rescue crews, submarines, and everywhere a compact emergency oxygen generator with long shelf life is needed. They usually contain a device for absorption of carbon dioxide, often a filter filled with lithium hydroxide; a kilogram of LiOH absorbs about half a kilogram of CO₂.

• Self-contained oxygen generators (SCOGs) are used in submarines.
• Self-contained self-rescue devices (SCSRs) are used to facilitate escape from mines.
• On the International Space Station, chemical oxygen generators are used as a backup supply. Each canister can produce enough oxygen for one crewmember for one day.
