Oxygen Generator (Emergency System)
Jump to navigation

An oxygen generator (emergency system), often a chemical oxygen generator, is a device that produces oxygen for emergency use. These systems are typically used in situations where a sudden loss of cabin pressure occurs, such as in airplanes, submarines, or mines.
How it works
Chemical Reaction
These generators utilize a chemical reaction to release oxygen.
Sodium Chlorate
A common chemical used is sodium chlorate, which decomposes when heated, releasing oxygen.
Ignition
The chemical reaction is initiated by a small explosion or ignition, often triggered by pulling on the oxygen mask.
Oxygen Flow
The resulting oxygen gas flows through tubing to the oxygen mask for breathing.
Compact and Long Shelf Life
These generators are designed to be compact, lightweight, and have a long shelf life, making them suitable for emergency situations.
Where they are used
- Commercial Aircraft: Emergency oxygen systems in airplanes, where oxygen masks deploy automatically or manually when cabin pressure drops.
- Submarines and Mines: As a backup oxygen supply in enclosed environments.
- Space Stations: For maintaining a breathable atmosphere.
- First Responders: Portable oxygen generators can provide medical-grade oxygen for ambulance and emergency services.
- Field Hospitals: Oxygen generators can provide a continuous supply of oxygen in remote locations or disaster situations.
