About Carbon Monoxide

Carbon monoxide (CO) is a poisonous gas. It cannot be seen, smelled or tasted, and can be fatal when high levels are inhaled. Symptoms of CO poisoning are similar to those of the flu and allergies. Carbon monoxide poisoning may also be misdiagnosed as a headache, stroke, food poisoning or heart disease. According to HUD, more than 500 people die from accidental CO poisoning each year in the U.S.

The Facts

Sources of carbon monoxide (CO) include:

  • Using the oven as heater
  • Air leaks from furnaces, water heaters or fireplaces
  • Ventless heater, fireplace or stove
  • Car exhaust from attached garage
  • Backdraft: an explosive surge in a fire produced by the sudden mixing of air with other combustible gases. It can occur in your home when there are duct leaks in the heating system, or when exhaust ventilation, such as from a clothes dryer or kitchen or bathroom exhaust fan, are greater than air replacement through infiltration or other means.

The Risks

At low concentrations:

  • Fatigue in healthy people
  • Chest pain in people with heart disease

At high concentrations:

  • Impaired vision and coordination
  • Headaches, dizziness and confusion
  • Nausea and reduced brain function
  • Unconsciousness
  • Death
