Winter Weather Awareness Week: Day 4 – Indoor Air Quality

During Minnesota winters, we spend more time indoors — making indoor air quality a critical safety issue. Today’s focus covers carbon monoxide (CO), radon, and moisture-related problems like mold.


🚨 Carbon Monoxide Safety

CO is colorless, odorless, and deadly.

  • Install CO alarms on every level of your home.

  • Never run vehicles inside a garage—even with the door open.

  • Keep dryer vents and furnace vents clear of snow.

  • If a CO alarm goes off, get outside immediately and call 911.


🏡 Radon Awareness

Minnesota has some of the highest radon levels in the nation.

  • Test your home every 2–5 years.

  • Radon test kits are low-cost and available year-round.


💧 Moisture & Mold

  • Use exhaust fans while cooking and showering.

  • Keep indoor humidity between 30–50%.

  • Clean up water leaks promptly to prevent mold growth.
