Candle flames are the source of heat and light. The NCA has several tips on how to burn them safely.
Candle flames are a source of heat and light. For safety, candle flames should be no greater than three inches, and should never be found anywhere other than on the original wick or wicks. Never handle or move a lit candle (Flame is HOT!). A candle’s flame should be stable, and kept away from drafts. The candle flame should not touch any container or material that is not designed for direct flame contact. Always read and follow the candlemaker’s instructions for use.
