Carbon monoxide (CO) is considered a silent killer because it is an odorless, colorless, tasteless gas. There’s one way to protect your family from carbon monoxide and that’s getting detectors installed in your home. Installation is simple, and the price is relatively inexpensive considering it could save your family’s lives.

Article Overview

Carbon Monoxide Detector Placement

Below are some places you should put a CO detector according to the NFPA (National Fire Protection Association):

  • Each level of your home
  • Central location outside of sleeping areas
  • Placement and mounting height should follow the manufacturer’s instructions

Most CO detector manufacturers also seem to agree that the devices should be placed 5-20 feet from the source of carbon monoxide (i.e., furnace, water heater, fireplace, etc.), and not near a window or door. You should also consider a carbon monoxide detector for your car.

Be sure to test these alarms every month and remember to change the batteries in your CO detectors. Many news outlets recommend changing your batteries when you turn your clocks back or forward for daylight savings time.

Tip

Label or mark the outside of your smoke and other detectors with the battery type(s) and last replacement date so you can easily reference each device (without having to disassemble or remember when you last changed the battery). We also recommend keeping extra batteries on hand for when they are low or need replacing. No one wants to listen to that annoying chirping sound.
