Always burn within sight.
Keep candles away from children and pets.
Keep away from things that can burn.
Place your candles on a stable, burn-proof surface.
Always trim your wick down to 1/4 of an inch before burning.
Remove any contaminates from the wick pool after cooling and before burning again, such as broken off wick pieces. It's normal for a wick to "mushroom" and break off as it burns.
Candles should only burn for 4 hours maximum at a time.
