What are the Dangers of Carbon Monoxide?

According to the Centers for Disease Control, approximately 20,000 people are taken to an emergency room and 400 people die every year from accidental carbon monoxide poisoning.

What are the symptoms of carbon monoxide poisoning?
Exposure to carbon monoxide can cause flu-like symptoms, including:

headache
dizziness
weakness
nausea
loss of muscle control

If you experience these symptoms after being in an enclosed area, go out into fresh air immediately. Seek emergency medical help if symptoms do not quickly improve. Prolonged exposure to carbon monoxide can lead to serious illness and even death.

Other ways to prevent carbon monoxide poisoning include:

Never use a gas oven or range to heat a room. This can deplete oxygen from the air and cause asphyxiation or severe carbon monoxide poisoning.
Ensure that any natural-gas-burning appliances are installed, maintained and used safely and according to manufacturer instructions. Gas appliances should be checked by a qualified technician periodically to ensure that they are working properly.

Do not allow vehicles, lawnmowers, snow blowers, or any gasoline-powered engine to idle in a garage attached to a house. Carbon monoxide can drift into the living space and create a hazardous situation.
Never use a generator or other fuel-powered machines inside. Hazardous carbon monoxide fumes are odorless and can quickly overwhelm you if a generator is used indoors. This includes outbuildings like sheds or garages.
