Carbon Monoxide

Carbon Monoxide

Carbon monoxide (CO) is a gas that can’t be seen or smelled but is dangerous-even deadly. It's made when fuels—like gas, kerosene, propane, or wood—are burned. In homes, carbon monoxide can quickly build up from a poorly vented or malfunctioning heater, furnace, range, fuel-powered appliances, or a car left idling in a garage.

Carbon monoxide is the most common cause of deadly poisonings. Protect yourself and your family by making sure you have working carbon monoxide detectors on every level in your home.

In homes, carbon monoxide can build up from burning any fuel type in common household appliances, including:

  • Idling cars in a closed garage.
  • Water heaters or clothes dryers.
  • Furnaces, boilers, wood stoves, fireplaces, or space heaters.
  • Ranges/stoves, cooktops, or wall ovens.
  • Portable generators.

Poorly vented, unvented, or malfunctioning appliances, and leaking chimneys and furnaces increase the risk of carbon monoxide. Electric or solar-powered appliances do not produce carbon monoxide.

Each year, more than 400 people die in the United States from accidental carbon monoxide poisoning, and around 50,000 people visit the emergency room.

In Wisconsin, around 500 people go to the emergency room each year because of carbon monoxide. That’s why Wisconsin law requires that each floor of a house have a carbon monoxide detector

Know the Signs and Symptoms of Carbon Monoxide Poisoning:

CO poisoning can happen any time of year, but it is more common in the fall and winter months. While some populations like infants, people with respiratory conditions, and those older than 65 are at increased risk of illness, anyone can experience symptoms of CO poisoning.

Symptoms of carbon monoxide poisoning include:

  • Headache
  • Fatigue
  • Dizziness
  • Shortness of breath
  • Nausea/Vomiting
  • Confusion
  • Impaired coordination, and
  • Loss of consciousness

At high levels, carbon monoxide can cause death within minutes. Go to fresh air and call 911 immediately if you see the symptoms of carbon monoxide poisoning or if your alarm sounds. Do not go back in the home until the fire department has inspected it and declared it safe.
