What is Carbon Monoxide?
Carbon monoxide, or "CO" is an odorless, colorless gas that can kill you.
Where is CO found?
CO is found in fumes produced any time you burn fuel in cars or trucks, small engines, stoves, lanterns, grills, fireplaces, gas ranges or furnaces. CO can build up indoors and poison people and animals who breathe it.
What are the symptoms of CO poisoning?
The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain and confusion. CO symptoms are often described as "flu like." If you breathe in a lot of CO it can make you pass out or kill you. People who are sleeping or drunk can die from CO poisoning before they have symptoms.
Who is at risk from CO poisoning?
Everyone is at risk for CO poisoning. Infants, the elderly, people with chronic heart disease, anemia or breathing problems are more likely to get sick from CO. Each year, more than 400 Americans die from unintentional CO poisoning not linked to fires, more than 100,000 visit the emergency room and more than 14,000 are hospitalized.
How can I prevent CO poisoning in my home?
- Follow the manufacturer's instructions on installing battery-operated CO detectors in your home and change the battery yearly. Check your CO detector regularly to be sure they are functioning properly.
- Have your heating system, water heater and any other gas or oil burning appliances serviced by a qualified technician every year.
- Have your chimney checked or cleaned every year. Chimneys can be blocked by debris and this can cause CO to build up inside your home.
- Seek prompt medical attention if you suspect CO poisoning and are feeling dizzy, light-headed or nauseous.
- Never use a generator, charcoal grill, camp stove or other gasoline or charcoal-burning device inside your home, basement or garage or near a window.
- Never run a vehicle inside a garage attached to your house, even if you leave the door open.
- Never burn anything in a stove or fireplace that isn't vented.
- Never heat your house with a gas oven.
- Never use a generator, pressure washer, or any gasoline-powered engine less than 20 feet from any window, door, or vent. Use an extension cord that is more than 20 feet long to keep the generator at a safe distance.
