Every year human error is responsible for starting a number of candle fires. Candles can be a serious fire hazard if not used properly. Reduce health and safety risks when you burn candles:

•    Never leave candles burning with no one in the room.
•    Never fall asleep or leave the house with candles burning.
•    Never burn candles close to items that can catch fire, like mattresses, bedding, curtains, cabinetry, upholstered furniture, decorations and clothing.
•    Never leave burning candles within reach of children or pets

Candles are safe when used responsibly and according to the manufacturer’s instructions.
