Carbon monoxide alarms sound an alarm when carbon monoxide is detected. CO is a toxic gas that cannot be seen, felt, tasted or smelled. The effects of CO poisoning can cause household members to become extremely ill or even cause death. Due to damage, poor maintenance, or defects, appliances like furnaces, ovens, fireplaces, kerosene heaters, and grills may silently emit CO. Advanced warning of CO poisoning is only possible if you install and maintain a CO detection device.
