Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can cause severe illness or death at high levels. Follow these essential CO detector guidelines to protect your home and family.

  • Where to Install: Place alarms on every level of your home, inside each bedroom, directly outside sleeping areas, and near attached garages.

  • Where to Avoid: Keep alarms at least 10 feet away from fuel-burning appliances, and avoid placing them inside bathrooms or right next to supply vents and ceiling fans.

  • Testing & Maintenance: Test alarms monthly using the test button, replace standard batteries every 6 months, and replace the complete unit every 7 to 10 years (or when the end-of-life signal sounds).

  • Emergency Response: If an alarm sounds, evacuate immediately to fresh air, verify everyone is accounted for, and call 911 from outside. Keep windows and doors closed so firefighters can accurately measure and trace the source of the gas.
