Carbon monoxide alarms

Carbon Monoxide is colorless, odorless and tasteless therefore it is undetectable without an alarm. Approved and operational CO Alarms are required within 10 feet of each lawfully used sleeping room. CO is roughly the same weight as air and is often accompanied with warm air so it should be placed considerably higher than your floor.
