Flying is one of the safest modes of transportation, but sometimes things can go wrong. In an event of a sudden cabin decompression, it's essential for all passengers to have access to emergency oxygen. Commercial aircraft are installed with an emergency oxygen system that includes yellow oxygen masks that drop from compartments above each passenger seat. In this blog, we'll take a closer look at the aircraft emergency oxygen system, in particular, the emergency oxygen generator.
What is an Emergency Oxygen Generator?
An emergency oxygen generator is a device used to provide oxygen for emergency situations. It's used in situations where there is a need for a self-contained oxygen source, where a person may not have access to a regular oxygen supply. In commercial aircraft, the emergency oxygen generator is used to provide emergency oxygen to passengers in the event of a cabin decompression. The emergency oxygen generator is a critical component of the aircraft emergency oxygen system.
How does it work?
Emergency oxygen generators are typically chemical oxygen generators or gaseous oxygen generators. Chemical oxygen generators use a chemical reaction to produce oxygen. The reaction typically involves a mixture of sodium chlorate and an igniter that's activated when the passenger pulls the mask towards themself. This causes a chemical reaction that produces oxygen. Gaseous oxygen generators, on the other hand, store compressed oxygen gas in a cylinder that can be released into the cabin in an emergency.
Where is the generator located?
The emergency oxygen generators are typically located in compartments under the passenger seats or in the overhead compartments. The location ensures easy access to the generators in case of an emergency. Each passenger is assigned a specific oxygen mask that can be accessed from these compartments.
Why is it important?
The emergency oxygen generator is an essential part of the aircraft emergency oxygen system. In case of a cabin decompression, the oxygen level can drop quickly, and passengers can lose consciousness in seconds. The emergency oxygen generator ensures that there is a quick and efficient supply of oxygen that's easily accessible to passengers. The emergency oxygen generator is designed in such a way that it automatically activates in case of a decompression, providing oxygen to passengers without requiring any intervention.
Conclusion
Emergency oxygen generators are critical components of aircraft emergency oxygen systems. They provide a quick and efficient supply of oxygen to passengers in case of a cabin decompression. Whether the emergency oxygen generator is a chemical oxygen generator or a gaseous oxygen generator, it's essential to have a reliable and efficient system in place. Remember always to listen to the safety instructions carefully and know how to use the yellow oxygen masks provided in case of an emergency.
