Introduction to carbon monoxide (CO)
Carbon monoxide is odorless, colorless and tasteless, but very toxic. Whether you heat your home with oil, natural gas, propane, coal or wood, your heating system can produce carbon monoxide (CO) if it is not working properly or if it is inadequately vented. CO is also produced from internal combustion devices such as a car or small gasoline engines. Signs indicating the presence of carbon monoxide in the home include stuffy, stale or smelly air, very high humidity or soot coming from a fireplace or heating system.
What are the symptoms of CO poisoning?
The symptoms of carbon monoxide poisoning are often confused with those of the flu and the highest incidence of poisoning occurs during flu season.
Symptoms include:
- headaches
- dizziness
- nausea
- unclear thinking
- shortness of breath
- weakness
- vision problems
- loss of muscle control
High concentrations of carbon monoxide can lead to unconsciousness, brain damage or death. However, a victim may not experience ANY of these symptoms. You should suspect the presence of carbon monoxide if symptoms tend to disappear when you leave your home.
What should you do if you suspect the presence of CO in
your home?
If you suspect the presence of carbon monoxide:
- Open the windows and doors and leave the house
- Immediately call your fuel supplier or a licensed heating contractor for an emergency inspection
- If carbon monoxide is detected, seek medical attention immediately
How can you reduce the risk of CO poisoning in the home?
To reduce the risk of carbon monoxide poisoning, have your heating system "tuned up" before the heating season begins to ensure that it is in good working order. Maintenance and servicing should always be done by a licensed heating contractor, your gas company or by your fuel supplier. Also, have your chimney or vent pipes checked for blockage. If a blockage exists, you should contact a professional chimney sweep immediately.
It is also a good idea to install a carbon monoxide detector and make sure your home is adequately ventilated, particularly if you have insulated your home, had major renovations done or have enclosed your heating system to increase living space.
