Carbon monoxide, also known as the "silent killer" is an odorless gas which kills hundreds of people every year, and leaves thousands more seriously ill.
It is important to know what causes carbon monoxide, how to minimize any effects, and why your family needs a carbon monoxide detector.
The more informed you are, the safer your family will be.
What is carbon monoxide? CO is a natural byproduct of home appliances that burn fuels like oil, kerosene, gas or charcoal.
Pretty much any tool or appliance that is not adequately vented and maintained can be a potential source of danger, including but not limited to: boilers or furnaces, water heaters, and stove tops.
Why is carbon monoxide harmful? Even low levels of CO an be detrimental to your health.
Breathing low levels of CO can cause a myriad of health problems including: shortness of breath, mild nausea, and headaches.
At higher levels of inhalation, it can cause drowsiness, nausea, vomiting, and confusion.
Worst case scenerio? High levels of CO or prolonged exposure can lead to loss of consciousness and in severe cases, death.
How do you prevent against carbon monoxide poisoning?

• Have your heating system, chimney and flue inspected and cleaned by a qualified technician every year.
  They should ensure there are no leaks, and that everything is drafting correctly.
  
• Don't operate gasoline-powered engines in confined areas.
  Always have fresh air sources available.
  
• If given an option, always choose vented appliances.
  
• Install a carbon monoxide detector (or two or three!) with an audible alarm in your home and garage.
  

Most towns and cities have mandates requiring carbon monoxide detectors be installed in specific places.
If you are installing only one CO detector, it is generally recommended it be located near the sleeping area, where it can wake you if you are asleep.
Additional detectors on every level and in every bedroom of a home will allow extra protection against carbon monoxide poisoning.
If you're planning to purchase a CO detector - or even if you already own one - make sure that it is labeled with UL (Underwriters Laboratories).
These CO detectors offer a long-term warranty, and that it's easy to self-test and reset.
Should your CO detector alarm suddenly go off:

• Check for symptoms of poisoning.
  is anyone experiencing nausea, headaches or worse?
• If anyone is suffering from any symptoms, get everyone out of the house and seek medical attention.
  
• If not, ventilate your home with fresh air, turn off all potential sources of CO, including your boiler or furnace and water heater, etc.
  
• If you are unable to determine the source of the CO, call your local gas company immediately.
