Carbon Monoxide in Your Home
Carbon monoxide (CO) is a poisonous gas you cannot see or smell. It is produced when liquid, solid or gas fuel is burned — such as natural gas, propane, oil, charcoal, wood and wood pellets. Dangerous levels can build up quickly in your home, garage, or other enclosed areas. CO poisoning is more often a problem in the colder months since that is when Vermonters burn fuel to keep warm and their homes are closed up.
