Place CO Alarms:

  1. In a central location on every level of the home’s livable space (including the basement) and at least 15 feet away from
    any fuel-burning appliance.
  2. Near or inside each sleeping area in the home.
  3. Inside the home near the door leading to the attached garage and in rooms over the garage.

Reminders: 

  • Test CO alarms monthly.
  • If possible, interconnect your CO alarms — when one sounds, they all sound.
  • Follow manufacturer instructions and all applicable laws and building codes for CO alarm placement and replacement frequency/schedule.
