The specific gravity of co is lighter than air. When traveling distances tend to travel faster than the air. In mines or long halls like in schools will accumulate in front of smoke and the smell of combustion. This can be dangerous because a person can be in an exposure zone before they're aware of the problem. Detectors should always be downwind of the thing being monitored. There's is tons of info on google about placement.
