Before You Start

Pick a pot or fryer that leaves several inches of clearanceOil expands and bubbles up when food goes in, and a pot filled too high will overflow. Fill only to the manufacturer's max line if you're using an electric fryer.
Fully thaw and dry any food before it goes near the oilWater is a very dangerous liquid when deep frying — when it hits oil around 350°F it turns instantly to steam, expanding fast and splattering hot oil. Pat meat and vegetables dry, and never fry anything still icy.
Choose an oil with a high smoke point (peanut, canola, vegetable, or refined sunflower)Lower smoke-point oils break down and smoke before you reach frying temperature.
Set a kitchen fire extinguisher within reach before you turn on the heatA Class K (or Class B) extinguisher is the right type for oil fires — a standard household extinguisher may not be rated for it.
Clear the stovetop or counter around the fryer of towels, paper, curtains, and anything else that can catch a spark or stray splash
Confirm a whole turkey or large item is fully thawed days in advance, not just on the surface if cooking a whole turkey or large itemA partly frozen turkey causes violent, dangerous splattering when it hits hot oil.

Setting Up an Outdoor Turkey Fryer

Set up a propane turkey fryer outdoors only, never in a garage, carport, or on a wooden deck if using a propane turkey fryerKeep all propane-fired turkey fryers outdoor only.
Place it at least 10 feet from your house, garage, deck railings, and any overhanging branches, on a flat, level, non-flammable surface if using a propane turkey fryerPlace your turkey fryer on a stable, level surface outdoors, at least 10 feet from your home, far from structures, wooden decks, house eaves and overhanging trees.
Keep the propane tank a couple of feet from the burner, with the hose routed away from the flame if using a propane turkey fryerA safe distance between the propane tank and the burner is about 2 feet.
Measure your oil fill level beforehand by lowering the turkey (or a stand-in) into the empty pot with water, marking the line, then using that same oil levelThis stops overflow once the turkey displaces it. Follow the fryer's own instructions for exact amount.
Cover any bare skin — wear long sleeves and mitts rated for high heat — before lowering food in or taking it out

Stay in the kitchen (or right by the fryer outside) the entire time oil is heating or food is cookingNever leave hot oil unattended, even for a minute.
Clip a deep-fry or candy thermometer to the pot so you can watch the temperature instead of guessing
Heat oil gradually rather than cranking it to maxMost foods fry best between 325°F and 375°F, and oil pushed past its smoke point can ignite.
Lower food in slowly and away from your body, using tongs or a basketThis avoids a splash of hot oil hitting your skin.
Turn off the heat immediately if the oil starts smoking heavily or bubbling toward the rimLet it cool before touching or moving the pot.

Fry in small batchesOverloading the pot drops the oil temperature and causes more foaming and overflow risk.
Keep the lid nearby (not sealed on) so you can smother a small flare-up quickly if needed
Keep kids and pets out of the kitchen or yard area while the fryer is onHot oil splashes are a common cause of serious burns to bystanders.
Turn pot handles inward and away from the counter edge if using a stovetop potSo nobody bumps or catches them.

Never pour water on an oil or grease fireWater turns instantly to superheated steam on contact with hot oil, and using water can cause flaming oil to spatter and spread.
For a small grease fire, turn off the heat source if you can safely reach it, then smother the flames with a metal lid or use your Class K/B extinguisherNever use flour, a large amount of baking soda, or a towel that isn't fire-rated.
Get everyone out and call 911 if the fire is spreading or you're not confident you can control it
Treat any oil burn immediately with cool (not ice) water and seek medical care for anything beyond a minor, small burn

Let the oil cool completely before moving, straining, or storing the potThis can take a few hours.
Strain cooled oil through a fine mesh or cheesecloth into a sealed container if you're reusing itDiscard oil that's dark, foamy, or smells off.
Dispose of used oil in the trash (sealed and cooled) or a recycling drop-offNever pour it down a drain, where it hardens and clogs pipes.
Wipe down splatter around the stove or fryer area promptlyCooled grease residue is still a slip and fire-fuel hazard left sitting.
