How to safely burn candles
Place the candle in a well ventilated room.
There should be at least 3 ft (910 mm) between the candle flame and the surface above it. If burning multiple candles, place them at least 3 in (76 mm) apart from each other.
This prevents the candles from creating their own drafts. Remove your candle from anything flammable.
