Carbon monoxide (CO) is a colorless, odorless gas emitted from fuel-burning appliances such as furnaces, stoves, or vehicles. Dangerous build-up can happen from blocked vents or faulty systems, making CO alarms essential for early detection. Because some hotels and rentals lack CO alarms, carrying a portable Kidde detector ensures your safety while traveling.
Use only alkaline Energizer E91, Gold Peak 15A, or Golden Power GLR6A batteries for reliable backup power. Avoid lithium batteries as they are not compatible with these detectors and may affect performance.
Experts advise installing a CO detector on every floor, including the basement, and inside or near every sleeping area. This approach ensures full coverage and quicker detection regardless of where carbon monoxide may accumulate.
If the alarm sounds, evacuate immediately to fresh air and call emergency services (911). Do not silence the alarm or attempt to identify the source yourself—wait for professionals to inspect and resolve any issues.
Yes, CO alarms lose their effectiveness over time. They should be replaced every 10 years according to manufacturer guidelines. Kidde CO alarms provide dependable 24/7 detection for a full decade to keep your home safe.
