The Sparwood Fire Department is reminding residents to make sure their exhaust vents are clear of snow, ice and other obstructions.
This comes after they responded to a call for a Carbon Monoxide alarm inside of a home.
SFD officials said a snowdrift had blocked off the exhaust vent for the furnace and caused CO to build up within the home.
If you smell gas or have a carbon monoxide alarm go off, exit the home and call 911 immediately.
