What is the source of carbon monoxide?

This problem can occur in any device which depends on burning fuel for heat or energy. For example, furnaces, boilers, room heaters, hot water heaters, stoves, grills and any gasoline engine (i.e. lawn mower) are included in this list of devices. What makes carbon monoxide so dangerous? Carbon monoxide is an odourless, colourless, gas which is very toxic. When carbon monoxide is inhaled, it produces an effect know as chemical asphyxiation.

Even at very low parts per million levels, the body is quickly affected by oxygen starvation. Exposure during sleep is particularly dangerous because the victim usually does not awaken. Why is CO a problem now? CO has been with us for many years. Fifiteen years ago our homes were built in a manner tha
