Ronald, The gravity of air is 1 and the gravity of Carbon Monoxide is .9657 (per the EPA), which is almost identical; however since CO is usually mixed with warm air expelled by the appliances, it tends to rise with the warm air. Because CO has nearly the same specific gravity as air, the alarms can be located either low (for plug-in units) or high on ceilings or 6" below ceiling on walls (avoid corners where air is dead)

Different kinds of explosive gas can be detected and it is recommended that any home that utilizes natural or propane gas have at least one explosive gas leak detector. The diffusion of carbon monoxide in air is relatively even, meaning that a source of carbon monoxide can distribute the gas evenly throughout the room and house
Figures suggest that there may be over 200,000 flues that have become hidden by renovations, building alterations etc, so it's worth checking if you have an older home or premises.

Acute exposure is easier to diagnose as the symptoms are more pronounced, but it is the more common chronic exposure symptoms that are more subtle and difficult to tell apart from other conditions. What to do if the alarm sounds It is essential to read the instruction manual accompanying the detector because it provides important information on where to place it, how to use it and what to do if the alarm goes off

A CO detector on the ceiling does absolutely no good because dangerous levels could have been reached before the CO ever gets that high (fills up a room). In general more is better if they are maintained and actually working, I would prefer to spend more for fewer quality sensors than buy a lot of cheap ones for the same money
