Understanding Carbon Monoxide Levels and Their Impact

Understanding Carbon Monoxide Levels and Their Impact

Carbon monoxide (CO) is a colorless, odorless gas produced by the incomplete combustion of carbon-containing fuels. Common sources include unvented kerosene and gas space heaters, leaking chimneys and furnaces, gas stoves, generators, and automobile exhaust from attached garages. (epa.gov)

Health Effects of Carbon Monoxide Exposure

At low concentrations, CO exposure can cause fatigue in healthy individuals and chest pain in those with heart disease. Higher concentrations may lead to impaired vision and coordination, headaches, dizziness, confusion, and nausea. At very high levels, CO exposure can be fatal. (epa.gov)

Average CO Levels in Homes

In homes without gas stoves, average CO levels range from 0.5 to 5 parts per million (ppm). Near properly adjusted gas stoves, levels are often between 5 to 15 ppm, while near poorly adjusted stoves, levels can be 30 ppm or higher. (epa.gov)

Protecting Yourself from CO Exposure

To reduce the risk of CO poisoning:

  • Maintain Appliances: Ensure that all fuel-burning appliances, such as furnaces, stoves, fireplaces, and water heaters, are inspected and maintained by a trained professional annually. (epa.gov)

  • Install CO Detectors: Place CO detectors near sleeping areas to alert you to dangerous CO levels. Ensure the device is certified to the most current Underwriters Laboratory (UL) standard 2034 or the International Approval Services (IAS) 6-96 standard. (epa.gov)

  • Ventilate Properly: Use exhaust fans vented to the outdoors over gas stoves and open flues when fireplaces are in use. Consider purchasing a vented space heater when replacing an unvented one. (epa.gov)

  • Be Cautious with Vehicles: Never run a vehicle in an attached garage, even with the door open, as CO can build up quickly in enclosed spaces. (epa.gov)
