Carbon Monoxide Information

Understanding the Risk
Each year in America, unintentional carbon monoxide poisoning claims more than 400 lives and sends another 20,000 people to hospital emergency rooms for treatment. The United States Fire Administration (USFA) and the National Association of Home Builders (NAHB) would like you to know that there are simple steps you can take to protect yourself from deadly carbon monoxide fumes.

Carbon Monoxide (CO)
Carbon monoxide (CO) is an odorless, colorless and toxic gas. Because it is impossible to see, taste or smell the toxic fumes, CO can kill you before you are aware it is in your home.

Symptoms of CO Poisoning
At lower levels of exposure, CO causes mild effects that are often mistaken for the flu. These symptoms include:
  • Disorientation
  • Dizziness
  • Fatigue
  • Headaches
  • Nausea
The effects of CO exposure can vary greatly from person to person depending on age, overall health and the concentration and length of exposure.

Sources of CO
CO gas can come from several sources, including:
  • Charcoal grills
  • Gas-fired appliances
  • Motor vehicles
  • Wood-burning furnaces or fireplaces
Who Is at Risk?
Everyone is at risk for CO poisoning. Medical experts believe that unborn babies, infants, children, senior citizens and people with heart or lung problems are at even greater risk for CO poisoning.

Taking Action When the Alarm Goes Off
What you need to do if your carbon monoxide alarm goes off depends on whether anyone is feeling ill or not.

If No One Is Feeling Ill
  1. Silence the alarm.
  2. Turn off all appliances and sources of combustion (i.e., furnace and fireplace).
  3. Ventilate the house with fresh air by opening doors and windows.
  4. Call a qualified professional to investigate the source of the possible CO buildup.
If Illness Is a Factor
  1. Evacuate all occupants immediately.
  2. Determine how many occupants are ill and determine their symptoms.
  3. Call your local emergency number. When relaying information to the dispatcher, include the number of people feeling ill.
  4. Do not reenter the home without the approval of a fire department representative.
  5. Call a qualified professional to repair the source of the CO.
Tips to Protect Against CO Poisoning
  • Install at least 1 carbon monoxide alarm with an audible warning signal near the sleeping areas and outside individual bedrooms. Make sure the alarm has been evaluated by a nationally recognized laboratory, such as Underwriters Laboratories (UL). Carbon monoxide alarms measure levels of CO over time and are designed to sound an alarm before an average, healthy adult would experience symptoms. It is very possible that you may not be experiencing symptoms when you hear the alarm. This does not mean that CO is not present.
  • Have a qualified professional check all fuel burning appliances, furnaces, venting and chimney systems at least once a year.
  • Never use your range or oven to help heat your home and never use a charcoal grill or hibachi in your home or garage.
  • Never keep a car running in a garage. Even if the garage doors are open, normal circulation will not provide enough fresh air to reliably prevent a dangerous buildup of CO.
  • When purchasing an existing home, have a qualified technician evaluate the integrity of the heating and cooking systems, as well as the sealed spaces between the garage and house. The presence of a carbon monoxide alarm in your home can save your life in the event of CO buildup.
