Place lit holiday candles in a safe location - away from flammable materials. And don't leave the house or go to sleep with them burning. In the event of an earthquake, they could fall and start a fire. Tinsel, though pretty on a tree, if eaten by a cat or small child could cause them to choke or have an intestinal blockage. If you use tinsel, place it high on your tree.
Many Topanga houses are old, without adequate electrical outlets.
Don't overload your outlets with too many extension cords. If you do use cords, position them safety to avoid tripping on them. While decorating your home, keep flammable objects away from burning fireplaces. Someone could get injured or at worst, killed. Christmas trees are beautiful when they are fresh and moist.
