What is carbon monoxide?

Carbon monoxide is a poisonous gas that cannot be seen or smelled and can kill a person in minutes. Carbon monoxide is produced whenever any fuel such as gas, oil, kerosene, wood, or charcoal is burned. Carbon monoxide can build up so quickly that victims are overcome before they can get help.

Once inhaled, carbon monoxide:

  • Can cause permanent brain damage.
  • Can cause chest pains or heart attacks in people with heart disease.

Symptoms of carbon monoxide poisoning

  • Headache
  • Weakness
  • Dizziness
  • Confusion
  • Fatigue
  • Nausea

Prevent carbon monoxide poisoning

  • Never burn charcoal inside homes, tents, campers, vans, trucks, garages or mobile homes.
  • Do not burn charcoal in the fireplace in your home.
  • Never use gasoline-powered equipment indoors.
  • Never use a gas oven to heat your home, even for a short time.
  • Never idle a car in a garage, even when the garage door is open.
  • Never sleep in a room while using an unvented gas or kerosene heater.
  • Make sure that chimneys and flues are in good condition and are not blocked.
  • Carbon monoxide warning devices may provide additional protection, but should not replace the other prevention steps.
