Firing Up The Furnace Can Pose CO Threat

FARMINGTON — As the days get colder, homeowners will be turning on their furnaces and stoves and lighting up their fireplaces. Before that happens, toxicologist Marc J. Bayer, MD, medical director of the Connecticut Poison Control Center at UConn Health Center, recommends that homeowners have their heating systems, wood stoves and fireplaces inspected and cleaned and any worn or faulty parts replaced to minimize the risk of carbon monoxide poisoning.

Carbon monoxide, or CO, is a byproduct of burning organic fuels that include oil, gas, wood, coal, and kerosene. It is poisonous and can be lethal.

Properly cleaned and operating heating systems can prevent carbon monoxide from entering the home, something especially important in newer, well-insulated homes, because they are designed to hold heat and trap CO if it is present. Inadequate ventilation or improper combustion in the heating system can also lead to dangerous levels of carbon monoxide.

CO is particularly dangerous it cannot be smelled, seen or tasted. The early signs of CO poisoning include headache, nausea, unclear thinking, shortness of breath, weakness, and loss of muscle control. Symptoms often mimic the flu, leading to misdiagnosis by both patient and physician. Be suspicious of CO poisoning if symptoms vanish upon leaving a regular indoor environment. Severe symptoms can include convulsions and unconsciousness that can lead to death.

“I strongly encourage people to have a carbon monoxide detector in their living space and in their bedroom areas. People are especially at risk while sleeping,” Dr Bayer said. “CO detectors are a simple and economical precaution that can save lives.”

If a CO detector alarm goes off, or if symptoms of carbon monoxide poisoning are experienced, go outside immediately, Dr Bayer said. Use a cell phone or a neighbor’s phone to call your local fire department or 911.
