Lighting the tree:
Use lights that have the label of an independent testing laboratory. Some lights are only for indoor or outdoor use, but not both
Replace any string of lights with worn or broken cords or loose bulb connections. Connect no more than three strands of mini string sets and a maximum of 50 bulbs for screw-in bulbs.
Never use lit candles to decorate the tree.
Always turn off Christmas tree lights before leaving home or going to bed.
After Christmas:
Get rid of the tree when it begins dropping needles. Dried-out trees are a fire danger and should not be left in the home or garage, or placed outside against the home. Check with your local community to find a recycling program. Bring outdoor electrical lights inside after the holidays to prevent hazards and make them last longer.
