IN: Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O ) at increased partial pressures. It is also known as oxygen toxicity syndrome, oxygen intoxication, and oxygen poisoning. Historically, the central nervous system condition was called the Paul Bert effect, and the pulmonary condition the Lorrain Smith effect, after the researchers who pioneered its discovery and description in the late 19th century. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs and eyes. Oxygen toxicity is a concern for underwater divers, those on high concentrations of supplemental oxygen (particularly premature babies), and those undergoing hyperbaric oxygen therapy.

IN: I made the suggestion about not needing them on the ceiling into a stern warning. If you install them on the ceiling (unless they're specifically designed for it - most aren't) it could be deadly. = incorrect Carbon monoxide is not heavier than air - in fact it is slightly lighter as CO has the RMM of 28 whereas air is slightly more than this. It is therefore almost neutral density. However in a normal room, thermal convection current dominate transport of gases in a room. The ceiling is a relatively good place to have a CO detector as long as air flow from convectional currents in not affected and any boundary layer is overcome.
