What is carbon monoxide?
Carbon monoxide, or CO, is an odorless, colorless gas that can cause sudden illness and death.

Where is CO found?
CO is found in combustion fumes, such as those produced by cars and trucks, small gasoline engines, stoves, lanterns, burning charcoal and wood, and gas ranges and heating systems. CO from these sources can build up in enclosed or semi-enclosed spaces. People and animals in these spaces can be poisoned by breathing it.

What are the symptoms of CO poisoning?
Common symptoms of CO poisoning are headache, dizziness, weakness, nausea, vomiting, chest pain, and confusion. Breathing a lot of CO can cause loss of consciousness and death. People who are sleeping or intoxicated can die from CO poisoning before ever experiencing symptoms.

How does CO poisoning work?
Red blood cells pick up CO quicker than they pick up oxygen. If there is a lot of CO in the air, the body may replace oxygen in blood with CO. This blocks oxygen from getting into the body, which can damage tissues and result in death.

Who is at risk from CO poisoning?
All people and animals are at risk for CO poisoning. Certain groups — unborn babies, infants, and people with chronic heart disease, anemia, or respiratory problems — will be affected more quickly. Each year, more than 500 Americans die from unintentional CO poisoning, and more than 2,000 commit suicide by intentionally poisoning themselves.

How can I prevent CO poisoning from my home appliances?

• Have your heating system, water heater and any other gas, oil, or coal burning appliances serviced by a qualified technician every year.
• Do not use portable flameless chemical heaters indoors. Although these heaters don't have a flame, they burn gas and can cause CO to build up inside your home, cabin, or camper.
• If you smell an odor from your gas refrigerator's cooling unit have an expert service it. An odor from the cooling unit of your gas refrigerator can mean you have a defect in the cooling unit. It could also be giving off CO.
• When purchasing gas equipment, buy only equipment carrying the seal of a national testing agency, such as the American Gas Association or Underwriters' Laboratories.
• Install a battery-operated CO detector in your home and check or replace the battery when you change the time on your clocks each spring and fall.

How do I vent my gas appliances properly?

• All gas appliances must be vented so that CO will not build up in your home, cabin, or camper.
• Never burn anything in a stove or fireplace that isn’t properly vented.
• Have your chimney checked or cleaned every year. Chimneys can be blocked by debris. This can cause CO to build up inside your home or cabin.
• Horizontal vent pipes to fuel appliances should not be perfectly level. Indoor vent pipes should go up slightly as they go toward outdoors

Never, Never, Never… Ok you get the point!

• Never use a gas range or oven for heating. Using a gas range or oven for heating can cause a build up of CO inside your home, cabin, or camper.
• Never use a charcoal grill or a barbecue grill indoors. Using a grill indoors will cause a build up of CO inside your home, cabin, or camper.
• Never burn charcoal indoors. Burning charcoal gives off CO.
• Never use a portable gas camp stove indoors. Using a gas camp stove indoors can cause CO to build up inside your home, cabin, or camper.
• Never use a generator inside your home, basement, or garage or near a window, door, or vent.

How can I avoid CO poisoning from my vehicle?

• Have a mechanic check the exhaust system of my car every year. A small leak in your car's exhaust system can lead to a build up of CO inside the car.
• Never run a car or truck in the garage with the garage door shut. CO can build up quickly while your car or truck is running in a closed garage.
