Oxygen Generator (Emergency System)

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[edit | edit source]
Chemical Reaction[edit | edit source]
These generators utilize a chemical reaction to release oxygen.
Sodium Chlorate[edit | edit source]
A common chemical used is sodium chlorate, which decomposes when heated, releasing oxygen.
Ignition[edit | edit source]
The chemical reaction is initiated by a small explosion or ignition, often triggered by pulling on the oxygen mask.
Oxygen Flow[edit | edit source]
The resulting oxygen gas flows through tubing to the oxygen mask for breathing.
Compact and Long Shelf Life[edit | edit source]
These generators are designed to be compact, lightweight, and have a long shelf life, making them suitable for emergency situations.
Where they are used[edit | edit source]
- 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.
