2. Chemical oxygen generator - Wikipedia

   en.wikipedia.org/wiki/Chemical_oxygen_generator

   A chlorate candle, or an oxygen candle, is a cylindrical chemical oxygen generator that contains a mix of sodium chlorate and iron powder, which when ignited smolders at about 600 °C (1,100 °F), producing sodium chloride, iron oxide, and oxygen at a fixed rate of about 6.5 man-hours per kilogram of the mixture. The mixture has an indefinite ...

3. Oxygen storage - Wikipedia

   en.wikipedia.org/wiki/Oxygen_storage

   Chemical oxygen generators store oxygen in their chemical composition, and can be used only one time. Oxygen Candles contain a mix of sodium chlorate and iron powder, which when ignited smolders at about 600 °C (1,112 °F) and results in sodium chloride, iron oxide, and oxygen, about 270 liters per kg of mixture.

4. Self-contained self-rescue device - Wikipedia

   en.wikipedia.org/wiki/Self-contained_self-rescue...

   Test bench for a miner's closed circuit self-rescuers. A self-contained self-rescue device, SCSR, self-contained self-rescuer, or air pack is a type of closed-circuit SCBA [1] with a portable oxygen source for providing breathable air when the surrounding atmosphere lacks oxygen or is contaminated with toxic gases, e.g. carbon monoxide.

5. Portable oxygen concentrator - Wikipedia

   en.wikipedia.org/wiki/Portable_oxygen_concentrator

   Portable oxygen concentrator used with bottle humidifier POCs operate on the same principle as a home concentrator, pressure swing adsorption . [ 6 ] The basic set up of a POC is a miniaturized air compressor , a cylinder filled containing the sieve, a pressure equalizing reservoir and valves and tubes.

6. Emergency oxygen system - Wikipedia

   en.wikipedia.org/wiki/Emergency_oxygen_system

   Diagram of a chemical oxygen generator system. There are currently three systems that are typically found on aircraft: A chemical oxygen generator system connected to all masks in the compartment. Pulling down on one oxygen mask removes the firing pin of the generator igniting a mixture of sodium chlorate and iron powder, opening the oxygen ...

7. High altitude breathing apparatus - Wikipedia

   en.wikipedia.org/wiki/High_altitude_breathing...

   The oxygen source may be chemical oxygen generators, high pressure portable gaseous oxygen storage systems (gas cylinders), on-board oxygen generating systems (oxygen concentrators), or liquid oxygen systems. [4] Chemical oxygen generation is commonly used on large commercial aircraft as a source for the emergency oxygen system for passengers ...

8. Oxygen breathing apparatus - Wikipedia

   en.wikipedia.org/wiki/Oxygen_Breathing_Apparatus

   A sodium chlorate oxygen candle in the base of the unit generates oxygen on start-up as the canister has to reach a high internal temperature before it will start generating oxygen. The circulation of exhaled air containing carbon dioxide through the canister starts the chemical process, usually taking less than five minutes to reach a stable ...

9. Vika oxygen generator - Wikipedia

   en.wikipedia.org/wiki/Vika_oxygen_generator

   Vika or TGK is an oxygen generating system for spaceflight. [1] It is a SFOG, or solid-fuel oxygen generator, a kind of chemical oxygen generator. [1] It has been used on the retired Mir space station and the International Space Station. [1] It was originally developed by Roscosmos to supplement the Elektron oxygen system on Mir. [1]
