What is carbon monoxide and why is a carbon monoxide (CO) alarm essential for homes, apartments, and travel?
CO is a colorless, odorless gas from fuel-burning appliances. Build-up can occur from faulty furnaces, blocked vents, or running vehicles. Since some hotels and vacation rentals lack CO alarms, always travel with a portable Kidde detector.
Where should a CO detector be installed on the wall?
Carbon monoxide (CO) evenly disperses in the air. Therefore, a CO detector can be installed anywhere on the wall.
How many carbon monoxide alarms do I need in my home?
Experts recommend installing a detector on every floor, including the basement, and in or near each sleeping area, ensuring full-home coverage and faster detection no matter where a leak occurs.
What should I do if my CO alarm goes off?
If the alarm sounds, evacuate to fresh air immediately and call 911. Do not silence the alarm or try to locate the source yourself; professionals should inspect for leaks or faulty appliances.
Do CO alarms expire, and how long do they last?
Yes, carbon monoxide alarms diminish over time and should be replaced every 10 years. Check the manufacturer's replacement guidelines. Kidde CO alarms offer 10 years of 24/7 detection.
