They can cause serious damages when not handled properly. PLEASE NEVER leave a candle unattended. If you are stepping out of the room for a second blow it out! They are not toys we play with. Fire is unpredictable and it’s in your home. It’s important to ALWAYS follow the safety instructions. Please read the steps to how to burning Candles below.
NEVER put water on any type of fire to extinguish it.

For similar reasons, water should never be used to extinguish burning grease or fat, which both behave similarly to wax.
