And it's deadly. We're talking about carbon monoxide, the leading cause of poisoning deaths in America. Carbon monoxide is present wherever fuel is burned, be it wood, gas, or oil. It's produced by gas appliances, fireplaces, and both gas and oil furnaces. Also by wood burning stoves, barbecues, and automobiles.
Proper ventilation helps prevent carbon monoxide from building up in the home.
Have a professional check your furnace and gas appliances for leaks and proper venting. Inspect chimneys, flues, and all other vents for leaks and obstructions as well. It's also a good idea to install a carbon monoxide detector for early warning of gas build-up. Learn more about staying healthy with the publications listed in the free Consumer Information Catalog. Prolonged exposure can result in vomiting, blackouts, and eventually brain damage or death.
