How safe are candelabras?
Arranging candles one above the other, on a fireplace mantle for example, can cause the top candle to burn irregularly as a result of heat rising from the one below and it may start to warp. Also, when you use the fireplace the heat can melt the candles. Any time candles are arranged very close to one another, it introduces additional risk. Never leave any candle burning unattended. When you leave a room, make sure all your candles are out.
