Position candles well away from flammable objects and materials and well away from any possible contact by pets or children.
Place candles on heat-resistant surfaces, which will not transmit heat to the furniture on which they are placed. Ceramics work well for this purpose. Candles should also be placed in heat-resistant bowls that will catch dripping wax, and secured in an appropriate holder so there is not the slightest possibility of the candle falling over or being blown or knocked over.
Never leave a burning candle unattended.
Never light a candle in a situation in which you might fall asleep before blowing it out.
When blowing out a candle, hold your index finger in front of the flame and blow at it. Air will flow around your finger, extinguish the candle from both sides and prevent hot wax from splattering.
Install a smoke detector in every room where candles are burned.
