Poll description: Snow can block the vents and chimneys that carry exhaust out of your home. We want to know where [City/Town] stands. When this poll closes, we’ll repost it with what to check and why. ##

Poll repost:
In the poll below, we asked, Are your home’s exhaust vents and chimney clear of snow?
[Insert your results here, for example: “X percent of you said you haven’t checked.”]
Snow can block the vents and chimneys that carry exhaust out of your home. When exhaust has nowhere to go, carbon monoxide can build up inside. It’s a gas you can’t see or smell. The U.S. Consumer Product Safety Commission estimates an average of 227 carbon monoxide deaths a year from consumer products from 2019 to 2021, and more than half happened from November through February.
Check these during and after a snowstorm, because drifts can form:
→ Furnace and water heater vents → Chimney and flue → Dryer vent
A blocked dryer vent is a fire hazard even if your dryer is electric, because lint can catch fire. Electric dryers don’t produce carbon monoxide, but a clear vent matters for safety either way.
Which vent did you check first, [City/Town]?
