Be alert to electrical hazards such as work electrical cords. Double-check that burners are shut off after using a stove or oven. Do not heat an apartment with a stove or oven. Keep supplemental heating devices 36 inches away form flammable materials. Do not use balconies, porches, or furnace rooms for storage.
Artificial trees are safer.
When using a real tree, choose a fresh tree that is not shedding its needles. Cut the trunk of the real tree at an angle and place it in a large, deep, non-tip stand filled with water. Set your tree away from exits, fireplaces, and heat sources. Use only small twinkle lights approved for indoor use. DO NOT overload electrical outlets.
