Study Notes
Oxygen Supply Systems
- Two methods exist for supplying oxygen to a system: chemical and gaseous.
- Chemical oxygen supply systems utilize Emergency Oxygen Containers (EOCs) for stowage.
- EOC doors are electrically operated and each has a solenoid.
- Solenoids can be activated automatically by a pressure switch or manually from the cockpit.
- Each EOC houses oxygen masks and a chemical generator that produces oxygen.
- Oxygen is not immediately available when an EOC door opens and masks fall out.
- Tightening the lanyards by pulling the masks initiates the oxygen generation process.
