Turn off all lights when you go to bed or leave the house. The lights could short out and start a fire. Portable outdoor GFCIs can be purchased where electrical supplies are sold. GFCIs can be installed permanently to household circuits by a qualified electrician. Choose tinsel or artificial icicles of plastic or nonleaded metals.
Leaded materials are hazardous if ingested by children.
Never use lighted candles on a tree or near other evergreens. Always use non-flammable holders, and place candles where they will not be knocked down. Before lighting candles, place them in non-tip candle holders on a sturdy, stable surface. Never burn candles near curtains, a holiday tree, or other decorations that may catch fire easily. Don't leave candles burning unattended, and keep them out of the reach of small children.
