Always trim wicks .5 cm before lighting. The first time you light your candle, let it burn for 3 hours to allow the melted wax to reach the edge of the container to prevent your candle from tunneling.
Never leave a burning candle unattended. Extinguish all candles when you leave a room or before going to sleep. Do not place a burning candle near clothing, books or anything flammable. Place candles on a stable heat-resistant surface. Keep lit candles away from drafts, ceiling fans and any air currents.
