When purchasing a live tree, check for freshness. A fresh tree is green, needles are hard to pull from branches and the needles do not break when bent between your fingers,. The trunk is sticky with resin, and the tree should not lose many needles when bounced on the ground.
Choose a sturdy tree stand designed not to tip over and be sure to keep the stand filled with water.
Carefully plan where your tree will be positioned. Make sure the tree is at least three feet away from any source of heat, and place the tree out of the way of traffic and do not block doorways.
Use only lights that have been tested for safety by a recognized testing laboratory and follow the manufacturer’s instructions on how to use tree lights. Check each set of lights, new or old, for broken or cracked sockets, frayed or bare wires, or loose connections, and discard damaged sets. Use no more than three standard-size sets of lights per single extension cord.
When purchasing an artificial tree, look for the label "fire resistant," and never use electric lights on a metallic tree.
Never use lighted candles to decorate a tree.
Turn off all lights when you go to bed or leave the house. The lights could short out and start a fire.
Keep a watchful eye on small children around the tree.
Safely dispose of the tree when it begins dropping needles. Dried-out trees are very dangerous and should not be left in a garage or placed against the house.
