According to Unity Point Health:
The Top Most Dangerous Hazard During the Holidays is…Fire:
-Make sure your tree is on a sturdy stand so no pets, kids or rambunctious adults can knock it over and catch carpeting, tree limbs or drapes on fire.
-All holiday lights should be unplugged and all candles extinguished at the end of the night.
-Have your fireplace examined before the first use.
