Three Causes of Christmas Tree Fires

Christmas trees are a beloved holiday tradition, but even these brightly lit and colorful decorations have a dark side. According to the National Fire Protection Association (NFPA), between 2015 – 2019, fire departments in the United States responded to an annual average of 160 house fires that involved Christmas trees. These fires may ignite for many reasons, and the Christmas trees themselves may not be to blame. Trees may fuel a fire, but we have identified three common holiday features that may serve as the origin and cause of Christmas tree fires.

A Christmas tree may fuel a fire caused by another source.

Electric Lights and Wires

This may seem like cheating because pre-lit Christmas trees have become so popular, but it’s important to remember that electricity is a heat source. According to the NFPA, nearly half of the residential Christmas tree fires they studied included decorative lights, wiring, cords or plugs, or other lighting equipment.

If their decorative lights are LEDs, Christmas tree owners may feel satisfied that the lights don’t generate enough heat to cause concern. However, they may not notice loose or broken bulbs while putting up and decorating their tree. Damaged bulbs may spark or overheat, igniting the tree. Meanwhile, older lighting that may generate heat could ignite a tree due to prolonged contact. No decorative lighting should be left unattended while powered on, and this is especially true for vintage lights.

These are the remains of an artificial Christmas tree and its lights after a fire.

Overloaded or Damaged Electrical Equipment

Homeowners may be tempted to imitate characters in their favorite holiday movies and attempt to have the best lighting display on the street. Overloaded extension cords or power strips can be dangerous. Manufacturers provide information about the number of watts they can handle, and instructions for their use. Christmas tree owners can find this information on the extension cord tag, and users risk failures if they do not adhere to the manufacturer’s specifications.

Owners should also check their lighting equipment for frayed cords every time they put up the tree or take it down. It’s also possible that lighting equipment may fail due to manufacturing defects, causing a fire even when the owner follows instructions.

Too many electric lights have been connected to this power strip.

Heat Sources

During the holiday season, nothing is as cozy as sitting in front of a glowing fireplace. A beautiful Christmas tree may seem like the perfect addition to the scene. However, that lovely tree may be a major fire hazard if placed too close to a heat source.

Embers from fireplaces or candles near a Christmas tree can make contact with boughs. Christmas trees should never touch radiators, space heaters, or any other heating appliance, which may cause artificial Christmas trees to melt and burn. Homeowners who prefer natural trees should water their tree frequently to prevent drying. Dried out natural trees are especially prone to ignite when placed too close to a heat source, but artificial tree owners should remember that plastics are susceptible to heat, too.

This is the plastic base of a natural tree that was never watered after decoration and ignited when a lit candle was placed too close to the tree.
