NEVER place cancdles near trees, curtains/drapes or other flammable items.
If you place a [real] tree in your house, cut about two inches off the base of the trunk and place it in a reliable stand that holds water. Keep the stand filled with water at all times so the tree does not dry out quickly.
Keep your [real] tree AWAY from fireplaces, radiators and other heat sources.
DO NOT block exits with your tree
Make sure your [artificial] tree is tested and labeled as FIRE RESISTANT.
If you have small children or animals, AVOID putting breakable ornaments near the base of the tree.
DO NOT use lights with frayed or bare wires, as well as loose connections.
TURN OFF all lights [interior and exterior] prior to going to bed or sleep.
UNPLUG all extension cords when not in use.
DO NOT use chairs, desks, or other furniture to put up holiday decorations. Use an appropriate step stool or ladder.
BE PREPARED for the winter! Create a "Survival Kit" for your home to include, but not be limited to: a working flashlight, extra batteries, first aid kit, non-perishable foods, extra warm blankets and clothing, etc.
