Do not overload extension cords, and do not connect more than three sets of lights to one cord. Turn off all holiday lights when you retire for the evening or leave home. Outdoor lights should be weatherproof and clearly identified as designed for outdoor use. Remove outdoor lighting as soon as the season is over. Even outdoor lights are not designed to withstand prolonged exposure to the elements.
Candles are a traditional and beautiful part of the season.
Keep candles a safe distance from other things, and remember that a flickering flame is a fascination to little children. Keep candles out of their reach. Never use lighted candles on a tree or near other evergreens. Always use nonflammable holders. Avoid placing small or breakable ornaments on lower branches where children or pets can reach them and knock them off.
