During the extreme cold, don't forget to check your outdoor exhaust pipes, to keep them clear of ice and snow.
Public safety agencies are reminding people to bundle up, take a look, and clear any blockages from these pipes. Not only can these clogged pipes wreak havoc on your furnace's operation, but it could cause a build-up of carbon monoxide inside the home, according to plumbing and heating company, Cocalico.
According to the Center for Disease Control, carbon monoxide is odorless and colorless, which can cause sudden illness and death.
Eastern Iowa Fireground Photos, a Facebook page devoted to fire safety and news posted a reminder about how to prevent dangerous ice buildup.
If you have an exhaust pipe, like the ones pictured, it's recommended that you carefully clear away built up ice, noting to use caution to not break the tube.
"If this exhaust were to become clogged, the chances of having carbon monoxide in your home (will) greatly increase," said the post from Eastern Iowa Fireground Photos.
MidAmerican Energy also echoed this warning, to ensure plastic intake and exhaust vent pipes are clear of snow and ice. Doing this can also help keep your home running at its most energy-efficient level.
You can prevent carbon monoxide exposure by having your heating system or any other gas, oil, or coal burning appliance serviced each year. You can also prevent exposure by installing a CO detector in your home
