Are carbon monoxide (CO) alarms installed and maintained in your home? Often called the invisible killer, carbon monoxide is an odorless gas created when fuels burn incompletely. The only way to detect carbon monoxide is with a working carbon monoxide alarm.

Approximately 50,000 people in the U.S. visit the emergency department each year due to accidental carbon monoxide poisoning. More than 430 people die per year on average in the U.S. from carbon monoxide poisoning. This doesn’t have to happen, carbon monoxide deaths are preventable. Follow these safety tips from the National Fire Protection Association (NFPA) and the U.S. Consumer Product Safety Commission (CPSC):

  • Never use a portable generator inside your home, garage, basement, crawlspace, or shed or on your porch. carbon monoxide can seep into the house through open windows, doors, or any type of vents such as for the dryer, exhaust fans, and even openings into the attic in the roof’s overhang.
  • Use a portable generator outside only, and place portable generators at least 20 feet away from your house. Use outdoor-rated, long extension cords to run power into your home.
  • Have your furnace, fireplace, and fuel-burning appliances checked by a qualified professional once every year.
  • Never burn charcoal inside homes or in semi-enclosed areas.
  • Don’t leave a car running in the garage.
  • Install carbon monoxide alarms on every level of your home and outside each separate sleeping area. carbon monoxide alarms should have battery backup.
  • Test carbon monoxide alarms once a month, and replace carbon monoxide alarms if they fail to respond correctly when tested.
  • Know the symptoms of carbon monoxide poisoning: headache, dizziness, weakness, nausea, vomiting, sleepiness and confusion.

If you suspect carbon monoxide poisoning, or your carbon monoxide alarm sounds, get outside to fresh air immediately, and then call 911. If you live in an area without access to 911, call your fire department.
