Carbon monoxide is a poisonous gas created when common fuels such as natural gas, oil, wood or coal burn incompletely. CO poisoning is most common in the winter.

  • This odorless, colorless, tasteless gas is often called the silent killer because it’s virtually undetectable without the use of technology like a CO alarm.
  • Install CO alarms on every level of your home and outside each sleeping area.
  • CO alarms are not a substitute for smoke alarms. Install both types in your home.
  • Purchase CO alarms from a reputable retailer.
  • Choose alarms that bear the label of a nationally recognized testing laboratory.
  • Test CO alarms at least once a month by pressing the TEST button.
  • Replace alarm batteries at least once a year. If an alarm chirps or beeps to indicate low batteries, replace them immediately.
  • Make sure everyone in your family knows what number to call for a CO emergency.
  • If your CO alarm sounds, immediately move to fresh air outside. Alert others in the home to the danger and make sure everyone gets outdoors safely.
