Why are oxygen candles used instead of a canister of compressed oxygen?
Compressed 02 can leak or explode. COGs won't, and have an long shelf lie. [stargate70]
This might be worth adding to the article: http://news.bbc.co.uk/2/hi/uk_news/england/6478127.stm David 12:27, 22 March 2007 (UTC)
I added information that the generators are found in the backs of the seats on some wide body airliners, such as the DC-10. Also, that an ATA DC-10 was destroyed while parked at O'Hare Airport, on August 10, 1986, because one O2 generator was triggered while it was in the back of a broken DC-10 seat, which was being shipped to a repair station in the cargo hold of ATA Flight 131.

Is the long description of the location of oxygen canisters on some jets really on-topic?
"Oxygen generator" directs to this page, but in fact there are other types of oxygen generators besides chemical generators. One type used aboard aircraft effectively separates nitrogen and oxygen in atmospheric air and can be used for neutral atmospheres in fuel tanks or oxygen supplies, but I don't see any mention of it here.

I came to look at this page after reading an article about what caused an explosion on HMS Tireless - the cause was apparently an oxygen generator, probably fouled by oil. This may be worth mentioning in the article alongside the Mir discussion. The article can be found here on pages 2/3:

"a kilogram of LiOH absorbs about half a kilogram of CO2".
2LiOH + CO2 → Li2CO3 + H2O
LiOH + CO2 → LiHCO3
If Li has 7, O has 16, H has 1 and C has 12 mass units, then the first equation suggests that 48 units of LiOH can absorb 44 units of CO2. The second equation suggests that twice as much CO2 can be absorbed.
I would be grateful if someone could explain why LiOH can only absorb half its weight in CO2. RTBoyce ( talk) 05:44, 18 September 2011 (UTC)
I presume this is similar chemistry to that in SolidOx_(welding). That article only mentions the chlorate, but there needs to be something oxidizable to generate heat, and to keep the reaction going. Gah4 ( talk) 22:27, 3 September 2019 (UTC)
How are pressure swing adsorption (PSA) oxygen generators classified as chemical oxygen generators? Please provide reliable source to support their inclusion. · · · Peter Southwood (talk): 16:46, 7 August 2023 (UTC)
