Holiday Safety Tip #3: Decorations. Use only flame-resistant materials to trim a tree. Choose tinsel or artificial icicles of plastic or nonleaded metals. Take special care to avoid decorations that are sharp or breakable. Keep trimmings with small removable parts out of the reach of children to prevent them from swallowing or inhaling tiny pieces. Avoid trimmings that resemble candy or food that may tempt a young child to eat them and possibly choke.
