Always put candles on a heat resistant surface. Put them in a proper holder. Tall candles need to be held firmly upright by the holder so they won't fall. The holder needs to be stable too, so it won't fall over either.
Position them away from curtains. Don't put candles near curtains or other fabrics - or furniture. And keep them out of draughts.
Be careful where you put them, especially what they are under. It's easy to forget that there's a lot of heat above a burning candle. If you put it under a shelf or other surface then it can burn the surface. Make sure there's at least three feet (one metre) between a candle and any surface above it.
Keep clothes and hair away. Don't put the candles in a place where you could lean above, you don't want to set fire to your clothes or your hair.
Keep children and pets away. Candles should be out of reach of children and pets.
Keep candles apart. Leave at least 10 cm (4 inches) between two burning candles.
Don't move them when they're burning. Extinguish candles before moving them. Also, don't let anything fall into the hot wax like match sticks.
Don't leave them burning unattended. Extinguish candles before you leave a room. Never go to sleep with a candle still burning.
Use a snuffer or a spoon to put them out. It's safer than blowing them and prevents sending sparks and hot wax flying.
Double-check they're out. Candles that have been put out can go on smouldering and start a fire. Make sure they're completely out.
