What precautions should I take before do

That's not a tarot question, so no cards — just practical safety. Here's what actually matters for candle work at home.

Before you light anything

• Know your exits. If a room has only one door, keep it unlocked and unobstructed.
• Clear a zone: no curtains, blinds, bedding, towels, paper, or synthetic fabrics within at least a metre of the flame. Work on a heat-resistant surface — tray, ceramic tile, or metal — never straight on a counter that might have a hidden flammable finish.
• Trim the wick to about 5 mm before every burn. A long wick throws sparks and soot.
• Have water and a fire blanket or metal lid within arm's reach, and know that water is not the first move for a wax fire — smothering is.

While it burns

• Stay in the room. This is the single most important rule; most candle fires start from candles left unattended.
• Never move a lit candle. If you must, extinguish, move, relight.
• Don't leave it burning while you sleep or leave the house, even "just for a bit."
• Keep it out of reach of children and pets — cats especially knock things over.

Choosing the wax and vessel

• Glass or ceramic vessels are safer than plastic or thin metal. Avoid candles in anything that can shatter.
• Check labels: some scented or "gel" candles are higher in fragrance load and burn hotter. Diffusers are a separate category with their own rules.
• Beeswax and soy burn cleaner; paraffin burns hotter and soots more. Either is fine indoors with ventilation.

If something goes wrong

• Flame gets to something soft: don't throw water on wax or oil fires. Smother with a metal lid or fire blanket, or drown it with baking soda if it's very small, and get out.
• Candle glass cracked or smoking heavily: extinguish, move outdoors, don't relight.
• Smoke that fills a room: extinguish, open a window, get everyone and pets out, ventilate before relighting.

Ventilation matters more than people expect — paraffin and fragranced candles release fine particles and VOCs. A cracked window during the burn is usually enough.
