As homeowners start turning on their furnaces, doctors and first responders warn of the increased risks of carbon monoxide poisoning from improperly functioning heating appliances and generators.

Carbon monoxide is an odorless, colorless gas produced any time a fossil fuel is burned, and when levels of carbon monoxide are too high, it can cause sudden illness and death, according to the Centers for Disease Control.

“It can accumulate in homes as a result of several different things, several different common household processes,” said Captain Brad French, public information officer for the Dayton Fire Department. A chimney that does not have proper venting could cause a build-up of carbon monoxide, along with appliances that are not functioning properly, like water heaters or furnaces.

“We oftentimes see a greater degree of those incidents in the wintertime just because that’s when people are starting to use the heating elements of their home,” French said. He recommended those who use chimneys to get them serviced annually, as well as for individuals to get their furnaces and water heaters serviced annually.

Individuals who run generators too close to their homes can also increase the risk of carbon monoxide poisoning, French said. Those using generators, pressure washers, or any gasoline-powered engine should keep those items at least 20 feet away from the home. The CDC recommends using an extension cord that is more than 20 feet long to keep a generator at a safe distance.

Vehicles running too close to the house or running in garages also pose a safety risk in terms of accumulating a build-up of carbon monoxide. French said it is not considered safe even if the vehicle is running in the garage with the garage door open. Cars should be completely out of the garage if they are running.

Vague symptoms could lead to death

When levels of carbon monoxide increase due to faulty equipment or poor ventilation, the carbon monoxide can cause problems with the body’s ability to transport oxygen. Red blood cells pick up carbon monoxide faster than they pick up oxygen, according to the Ohio Department of Health. If there is a high concentration of carbon monoxide in the air, the body may place carbon monoxide into the blood instead of oxygen.

“That results in nausea, headaches, unconsciousness, and potentially even death,” French said.

More than 400 Americans die from unintentional carbon monoxide poisoning each year, according to the CDC. The CDC also reports more than 20,000 Americans visit the emergency room and more than 4,000 Americans are hospitalized each year due to carbon monoxide poisoning.

Doctors warn that the symptoms of carbon monoxide poisoning can be non-specific, which can also include fatigue, dizziness, and confusion in addition to headaches and nausea.

“It really depends on the levels of carbon monoxide that are present,” said Dr. Mark Williams of the Premier Physician Network. A car running in a closed garage would not take much time, but a slow leak from malfunctioning appliances may take more time for the symptoms to become more prevalent.

“It can be fatal,” Williams said. “If you seek treatment in a timely fashion, there generally are no lasting effects.”

With the symptoms being ambiguous, carbon monoxide might get misdiagnosed as the cold or flu during the fall and winter months.

“I think that’s a danger because the symptoms are super non-specific,” Williams said.

If someone is experiencing persistent symptoms of headaches and nausea, but not other symptoms like a fever or vomiting that might be associated with the flu or other illness, doctors recommend getting a carbon monoxide detector to see if there are dangerous levels of carbon monoxide in the home.

Experts recommend carbon monoxide detectors

There are a variety of different types of carbon monoxide detectors, French said. Some detectors can be plugged in to an outlet, and others are battery-operated. There are some dual carbon monoxide and smoke detectors. For detectors that are battery-operated, experts recommend changing the batteries regularly, such as when daylight savings time begin and then again when daylight savings time ends.

“We recommend everybody have smoke alarms and carbon monoxide alarms, whether those be standalone or combination detectors,” French said. Ten years is also the maximum life of a smoke detector.

If a carbon monoxide detector alarm goes off, those present should exit the home and call the fire department.

“We have multiple gas meters that we’ll show up with and can test that home and all different levels of the home to make sure that’s a safe environment,” French said.

Winter time fire concerns

Heating homes properly can also protect against winter time fires in addition to carbon monoxide poisoning.

“Space heaters need space,” French said. He recommended space heaters have at least three feet of open space on all sides of them.

Experts also recommend against heating homes with devices that are not approved for that function, such as with stoves.

“That’s very, very dangerous,” French said.

Doctors also warn against the risk of contact burns from heating elements.

“The most common burns we see in winter for children are contact related—touching the fireplace window or accessories, contact with space heaters or hot grills from old floor heaters, fire pits and grills and scalds from hot cocoa or soups,” said Dr. Petra Warner, chief of staff at Shriners Children’s Ohio. “Burning trash, leaves or debris is another common form of injury in older children and adolescents.”

Parents and adults should keep children away from open fires and do not leave children unattended around fire places, Warner said.

“Always keep young children away from stoves so that cooking items don’t accidentally spill onto them and likewise with a space heater. Don’t allow children to play near heaters to avoid falling onto them, but also know that space heaters can lead to house fires if used incorrectly or left running unattended overnight,” Warner said.

Autumn is also time to be prepared for winter time fires should an accident occur.

“In the fall is always a good time to practice your home fire escape plan before it gets a little too cold to do so in the winter,” French said.

How can carbon monoxide exposure be prevented?

There are many preventive measures you can take to prevent carbon monoxide poisoning in your home. The Ohio Department of Health provides the following list of actions to take:

  • Have your heating system, water heater and any other gas, oil, or coal burning appliances serviced by a qualified technician every year.
  • Install a battery-operated carbon monoxide detector in your home and check or replace the battery when you change the time on your clocks each spring and fall. If the detector sounds, leave your home immediately and call 911.
  • Seek prompt medical attention if you suspect carbon monoxide poisoning and are feeling dizzy, light-headed, or nauseous.
  • Don’t use a generator, charcoal grill, camp stove, or other gasoline or charcoal-burning device inside your home, basement, or garage or near a window.
  • Don’t run a car or truck inside a garage attached to your house, even if you leave the door open.
  • Don’t burn anything in a stove or fireplace that isn’t vented.
  • Don’t heat your house with a gas oven.
