What Causes Carbon Monoxide In A House

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can have serious health impacts when present in a home environment. Understanding what causes carbon monoxide buildup in a house is crucial for ensuring the safety of its occupants.

Top Takeaways

  1. Carbon monoxide is a byproduct of burning fossil fuels and can accumulate indoors due to improper ventilation or malfunctioning appliances.
  2. The main sources include gas stoves, furnaces, fireplaces, and vehicles left running in attached garages.
  3. Proper maintenance of appliances and ensuring ventilation can significantly reduce CO risks.

Identifying Sources of Carbon Monoxide

Various home appliances and situations can lead to carbon monoxide emissions. Here are some common sources:

  • Gas appliances: Stoves, ovens, and furnaces that are not functioning correctly or are inadequately ventilated.
  • Fireplaces and chimneys: Blocked chimneys can cause CO to build up in living spaces.
  • Vehicles: Cars running in attached garages, even with the garage door open, can lead to dangerous CO levels.
  • Portable generators: Especially during power outages, using these in or near the home can be fatal.
