Where to place carbon monoxide detectors

At least one carbon monoxide detector must be installed on each floor of your home, including the basement. You’ll also want to consider adding a detector in your garage if it’s attached to your home. And most importantly, install a carbon monoxide detector inside or directly outside of each bedroom or sleeping area. The effects of carbon monoxide are nearly impossible to detect when sleeping. If CO is detected, the alarm will sound to alert and wake you. Here’s what to keep in mind when installing carbon monoxide detectors in your home.

Carbon monoxide detector installation tips

As you think about where to place carbon monoxide detectors, there are a few points to keep in mind for your safety.

Always remember to….

  • Before installing, check to make sure the detector is approved by Underwriters Laboratories (UL) to meet strict testing and safety requirements
  • Read the carbon monoxide detector’s manual before installing for proper set-up
  • Install CO detectors at least 15-20 feet from gas-powered home equipment including stoves, dryers and furnaces
  • Install CO detectors within 10 feet of your garage if it’s attached to your home
  • Connect multiple detectors when possible for all alarms to sound when one detects carbon monoxide

Don’t install the detector….

  • Near any gas or fossil fuel area to avoid false CO detection
  • In humid or moist areas including bathrooms
  • In direct sunlight as it could overheat
  • Within reach of children to avoid easily tampering or damaging
  • Near windows or windy areas
  • Behind doors, cabinets, curtains or other areas to prevent CO detection
