The leading cause of accidental poisoning deaths all over the world, Carbon Monoxide (CO) is odorless, tasteless and invisible, poisonous gas. It is produced by the incomplete burning of solid, liquid, and gaseous fuels. Appliances fueled with natural gas, liquefied petroleum (LP gas), oil, kerosene, coal, or wood may produce CO. Burning charcoal produces CO. Running cars produce CO. The only safe way to know if carbon monoxide is present is to install CO alarms(CO detector) on every level of your home and in sleeping areas.
