Take care with scented candles. These kinds of candles turn to liquid to release their fragrance, so put them in a glass or metal holder.

 Always keep a burning candle within sight. Extinguish all candles when leaving a room or before  going to sleep.

Never burn a candle on or near anything that can catch fire. Keep burning candles away from furniture, drapes, bedding, carpets, books, paper, flammable decorations, etc.

Keep candles out of the reach of children and pets. Do not place lighted candles where they can be knocked over by children, pets or anyone else.

Trim candlewicks to ¼ inch each time before burning. Long or crooked wicks cause uneven burning and dripping.

Keep burning candles away from drafts, vents, ceiling fans and air currents. This will help prevent rapid, uneven burning, and avoid flame flare-ups and sooting. Drafts can also blow lightweight curtains or papers into the flame where they could catch fire.

Don't burn a candle all the way down. Extinguish the flame if it comes too close to the holder or container. For a margin of safety, discontinue burning a candle when 2 inches of wax remains or ½ inch if in a container.

Extinguish a candle if it smokes, flickers repeatedly, or the flame becomes too high. The candle isn't burning properly and the flame isn't controlled. Let the candle cool, trim the wick, then check for drafts before re-lighting.

Never use a candle as a night light.
