ur edit in smoke detector

hey! what was the exact reason for this (changing CO2 to CO)? CO comes later (when combustion gets incomplete)... CO2 is there from the start and spreads fast due to convection... bye --Homer Landskirty (talk) 14:17, 19 November 2008 (UTC)[reply]

AFAIK (but IANAE), the smoke-detector manufacturers don't sell CO2 detectors, named as such (I did a search at the time, and wasn't able to find any), but a number of them do sell CO detectors, or smoke/CO detector combos. Also, CO2 is not so much toxic by itself, as the lack of oxigen --or in combination with the CO produced by a fire-- is toxic. CO2, although not particularly helpful while still in the blood stream, is not toxic in the way CO is. CO "wants" to become CO2, so two CO molecules can split an O2 molecule in the blood stream, to form two not-so-useful CO2 molecules, thus depriving the body of oxygen. Like I said, I'm not an expert, so I don't mind you editing back the info about CO2.BlueCerinthe (talk) 07:24, 27 November 2008 (UTC)[reply]

the pdf file in the ref says that CO2 is proven to be the best indicator for fire (but the author produces CO2 detectors *giggle*)... CO2 can be harmful at low levels (4% CO2 act as anaesthetic), hot CO2 can spread quickly, high CO2 is there from the start; while CO needs incomplete combustion, which is not necessarily the case in every fire (e. g. modern cars try to produce as less CO as possible... lambda sensor)...

when normal conditions r re-installed (e. g. by fresh air): indeed CO inhibits blood cells for a longer time than CO2 does, but that doesnt matter in an active fire... --Homer Landskirty (talk) 07:49, 27 November 2008 (UTC)[reply]
