When using a patio fire pit, place it on a non-flammable surface at least 10 feet from your house, trees, or fencing. Use a spark screen to prevent embers from escaping, and keep a hose or fire extinguisher nearby. Never leave the fire unattended, and avoid burning wet or treated wood, which can release harmful chemicals.
