Understanding Carbon Monoxide Levels: A Comprehensive Guide

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

What Are the Health Effects of Carbon Monoxide Exposure?

Exposure to elevated CO levels can lead to a range of health issues. At low concentrations, individuals may experience fatigue, chest pain, impaired vision, headaches, dizziness, confusion, nausea, and flu-like symptoms. At higher concentrations, symptoms can escalate to unconsciousness and death. Certain groups, including fetuses, infants, the elderly, and individuals with heart or respiratory conditions, are particularly susceptible to CO poisoning. (epa.gov)

What Are the Average Carbon Monoxide 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 reach 30 ppm or higher. (epa.gov)

How Can You Protect Yourself from Carbon Monoxide Exposure?

To minimize the risk of CO exposure:

  • Maintain Fuel-Burning Appliances: Ensure that all fuel-burning appliances, including furnaces, water heaters, and stoves, are properly installed, maintained, and used according to the manufacturer's instructions. (epa.gov)

  • Install CO Detectors: Place carbon monoxide detectors near sleeping areas and on every level of your home. These devices can alert you to dangerous CO levels, but they should not replace proper maintenance of fuel-burning appliances. (epa.gov)

  • Ventilate Properly: Use exhaust fans vented to the outdoors over gas stoves and open flues when fireplaces are in use. Ensure that chimneys and flues are connected, in good condition, and not blocked. (epa.gov)

  • Avoid Idling Vehicles Indoors: Never leave a car running in an attached garage, even with the door open, as CO can build up quickly in enclosed spaces. (epa.gov)

What Are the National Ambient Air Quality Standards for Carbon Monoxide?

The U.S. Environmental Protection Agency (EPA) has established National Ambient Air Quality Standards (NAAQS) for CO to protect public health and the environment. These standards set permissible levels of CO in outdoor air to minimize health risks. (epa.gov)
