CANDLE BURNING SAFETY & GUIDELINES

Always keep a burning candle within sight. Shadows the candle company says candle light is awesome but, please stay safe.

Never burn a candle on or near anything that can catch fire. ie; drapes, bedding, carpets, books, paper, flammable decorations, etc.
Keep candles out of the reach of children and pets. Don't place lighted candles where they can be knocked over by pets or children.
Trim candlewicks to 1/4 inch each time before burning. Long or crooked wicks cause uneven burning and dripping.
Always keep your candle out of direct sunlight...the sun will tend to discolor the candle. 

Heat will affect your candle....if the room gets to hot it will cause it to soften and taller candles will start to bow. Cold will affect your candle....if the area where you keep your candle is extra cold it could cause cracks in your candle.

Always use a candle holder specifically designed for candle use. The candle holder should be heat resistant, sturdy and large enough to safely hold the candle. Be sure the candle holder is placed on a stable, heat-resistant surface. This will also help prevent damage to the surface the candle is setting on.

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 can catch on fire.
Always burn candles in a well-ventilated room. Don't burn too many candles in a small room or in a "tight" home where air exchange is limited.
Never touch or move a burning candle when the wax is liquid. 
Place burning candles at least three inches apart. This ensures they won't melt one another, or create drafts that can cause the candles to flare.
Use a snuffer or extinguish the flame by "drowning" it in the wax. Never extinguish with water.
It's the safest way to prevent hot wax splatters.

When using a candle in a lantern (glass or metal) make sure there is at least 2 inches between the candle and the surface it's in. When using a lantern (glass or metal) for a candle larger than a 4" diameter make sure the panel with the hinge is left open and the "top" is open.  The candle needs proper air flow through the lantern to keep the area well ventilated so heat does not build up around the candle.  This ensures proper burning and ventilation.  Never leave unattended. Also, check with the guidelines of the manufacturer of the lantern.
Never use a candle as a night light.
