Trees

Try to select a fresh tree by looking for one that is green. The needles of pines and spruces should bend and not break and should be hard to pull off the branches. On fir species, a needle pulled from a fresh tree will snap when bent, much like a fresh carrot. Also, look for a trunk sticky with sap.

Cut off about two inches of the trunk and put the tree in a sturdy, water-holding stand. Keep the stand filled with water so the tree does not dry out quickly.

Stand your tree away from fireplaces, radiators and other heat sources. Make sure the tree does not block foot traffic or doorways.

If you use an artificial tree, choose one that tested and labeled as fire resistant. Artificial trees with built-in electrical systems should have the Underwriters Laboratory (UL) label.

Lights

Only use indoor lights indoors (and outdoor lights only outdoors). Look for the UL label. Check lights for broken or cracked sockets, frayed or bare wires, or loose connections. Replace or repair any damaged light sets.

Also, use no more than three light sets on any one extension cord. Extension cords should be placed against the wall to avoid tripping hazards, but do not run cords under rugs.

Turn off all lights on trees and decorations when you go to bed or leave the house.
