Kitchen Fires
Home fires happen to 2 million Americans each year, with almost half caused by cooking equipment. Unattended cooking is the number one cause of cooking fires. Never leave food that is boiling, broiling, frying, or grilling unattended. Set a timer to check on food frequently when baking, roasting, and simmering.
Be Prepared
- Keep baking soda easily accessible in case of a grease fire.
- Keep baking sheets or lids for pots and pans close by to smother a fire quickly.
- Have a kitchen fire extinguisher – know its location, what type it is, and how to use it.
- Install battery-powered smoke detectors on each house level and in the garage; test them twice a year.
Safety Tips
- Roll up long sleeves when cooking to prevent them from catching fire.
- Turn pot and pan handles towards the back of the stove.
- Maintain a kid-free and pet-free zone three feet around the oven or stove to prevent accidental burns and to keep flammable items out of the area.
- Use a dry oven mitt or potholder, rather than a towel, to remove food from the oven and stove. Towels can easily fall onto a heat source and ignite.
- After cooking, ensure the stove or oven is turned off. Unplug small appliances when not in use.
- Clean up spills on cooking surfaces to prevent grease buildup and potential fires.
- Ensure appliances are completely cool before cleaning.
Storage Cautions
- Do not use the oven as storage. Preheating an oven filled with storage containers could easily lead to a fire.
- Avoid storing pots, pans, plastic, paper, and cloth above the stove. Items can easily fall onto the stove and catch fire, and individuals can quickly be burned if they reach for an item when the stove is on.
- Store household cleaners away from the stove, oven, and other kitchen heat sources.
Appliance Safety Precautions
Microwaves
Read manufacturer labels to learn if items are oven or microwave-safe or resistant to other heat sources.
Do Not Use in a Microwave
- Aluminum foil
- Metal cookware, utensils, bowls, pans, and measuring cups
- Paper bags
- Recycled paper products, such as napkins and paper towels. They may contain minute metal flecks that can spark.
- Styrofoam
- Twist ties
Ovens
- To prevent flames, put a baking sheet under foods high in fat or likely to drip.
- Use correct oven settings. Accidentally turning on broil rather than bake may lead to burning food and a potential fire.
- Use thermal-shock-resistant glass in the oven. To avoid the risk of thermal shock, which can cause glass to shatter, do not store glassware in the oven and always preheat the oven before cooking food in glassware.
- When in doubt, always look for cookware or material explicitly labeled oven safe.
- Avoid using wet or damp potholders, oven mitts, or towels. Wet material transfers heat more quickly than dry material and can cause a burn.
Oven-safe Materials
- Aluminum, cast iron, carbon steel, or stainless steel bakeware (always check the manufacturer's label)
- Aluminum foil
- Parchment paper
- Silicone bakeware
- Tempered glass bakeware
Do Not Use in an Oven
- Cardboard
- Items with wood, plastic, or rubber parts
- Paper products (paper towels or napkins, paper plates, or paper bowls)
- Plastics
- Wax paper
- Wooden items
Toasters
- Keep toasters unplugged when not in use. If the toaster is located near something flammable, it can spark a fire whether the lever is up or down.
- Clean the toaster regularly. Crumbs that accumulate at the bottom of the toaster can spark a fire.
- Do not force thick foods into a toaster. This may cause the food to get stuck in the toaster, burn, and ignite a fire.
Fryers
- Heat oil slowly to temperature.
- If the oil smells or starts to smoke, it is getting too hot. Turn off the burner and remove the pan from the heat.
- Smoke point: Most cooking oils reach their smoke point between 350 to 450 F.
- Flash point: The point where most cooking oils start creating flammable vapors is 600 F.
Deep Fat Frying and Fire Prevention
- Read the manufacturer’s directions before use.
- Keep the fire extinguisher close.
- Keep direct flames away from oil; oil is highly flammable.
- Keep water away from oil when deep-fat frying. Water vaporizes instantly, changing to superheated steam.
- Remove ice crystals from frozen food.
- Pat dry thawed or fresh food before placing it in a deep fryer.
Cautions
- Never leave a deep fryer unattended.
- Never use plastic when deep frying. It can easily melt.
- Never overcrowd a deep fryer. This can cause uneven cooking and oil to overflow.
- Never deep fry a turkey that weighs more than 12 pounds.
- Never fry a turkey indoors; always fry a turkey outdoors in a safe location.

Kitchen Fire Extinguishers
Knowing where a fire extinguisher is and how to use it is essential for food and kitchen safety. Be prepared by purchasing the right type of extinguisher and knowing how to store, use, and inspect it properly.
How to Use a Fire Extinguisher
The PASS method is an acronym to help you remember the steps for using a fire extinguisher.
- P: Pull the pin.
- A: Aim the nozzle low towards the base of the fire, standing at least 6 feet from the fire.
- S: Squeeze the lever slowly and hold it.
- S: Sweep the nozzle from side to side while moving toward the fire.
If the fire does not go out immediately, leave the area. Make sure to call the fire department anytime you need to use a fire extinguisher.
Different types of fire extinguishers contain different extinguishing agents for putting out specific types of fires. Each extinguisher will be labeled with a letter — or a combination of letters — to denote which types of fire they can put out.
- Fire extinguishers for the kitchen should be labeled with at least B or K.
- Common household extinguishers are labeled A-B-C.
- Multipurpose fire extinguishers may be labeled with a combination of letters such as B-C or A-B-C.
- Most kitchen fires involve grease. A fire extinguisher with only a class A label will not work on a grease fire.
- All fire extinguishers should have a seal that indicates an independent testing laboratory has tested them. Often, the seal is a UL label.
| Type of Fire Extinguisher (Letter) | Best Used For | Use In |
|---|---|---|
| A | Cloth, wood, and paper | Homes and businesses |
| B | Combustible and flammable liquids, such as grease, oil, and oil-based paints | Homes and businesses |
| C | Plugged-in electrical equipment, such as appliances and tools | Homes and businesses |
| D | Flammable metals | Factories |
| K | Vegetable oils, animal oils, and fats in cooking appliances | Commercial kitchens, restaurants, cafeterias, and catering businesses |
Extinguisher Sizes
Choose a fire extinguisher that is large enough for a small fire but not heavy. For home use, a 5-pound fire extinguisher is generally recommended.
Installation and Storage
Install fire extinguishers close to exits, and keep them at least 30 feet from the stove, if possible. Do not store your fire extinguisher in a cabinet or a hard-to-reach place in the kitchen. In an emergency, it should be easy to grab.
Monthly Inspection
Inspect the fire extinguisher once a month.
- Check the extinguisher’s pressure gauge to ensure it’s still in a safe operating range.
- Inspect the hoses and nozzles for physical damage and check for rust or dents. Clean the outside to remove dust or grease.
- Lift the extinguisher to make sure it is full. If it is light, it may leak.
- Shake chemical extinguishers monthly to prevent the chemicals from solidifying and settling. Read the label on the extinguisher.
- Check the label or attached tag for an expiration date. According to National Fire Protection Association standards, rechargeable fire extinguishers are good for 6 years, and disposable fire extinguishers are good for 12 years.
Kitchen Clean-Up After a Fire
Contact the fire department to assess the severity of the fire. When in doubt, throw it out. Discard food that has been near a fire or exposed to heat, smoke, fumes, extinguishing chemicals, or water.
Cans, Bottles, and Jars
Heat from a fire can cause food spoilage in cans and jars. Exposure to extreme heat may also split or rupture jars and
canned food. Throw these out.
Canned Food and Cookware
Canned food, pots, and pans can be decontaminated. Wash them first in hot, soapy water. Mix and submerge for 15 minutes in a mixture of 1 Tablespoon of regular, unscented household bleach per 1 gallon of water.
Countertops and Kitchen Surfaces
Use hot, soapy water to wash down surfaces. Rinse and sanitize using 1 Tablespoon of regular, unscented household bleach per 1 gallon of water. Allow surfaces to air dry.
Food on Shelves, Counters, and Cabinets
After possible exposure to heat or toxic fumes, discard any food, spices, and extracts packaged in cardboard, plastic wrap, aluminum foil, paper, cloth, screw-topped jars, or storage canisters.
Food in Refrigerator and Freezer
Refrigerator and freezer seals are not airtight; toxic fumes from a fire can get inside.
Food Containers
Chemicals used to fight fires cannot be washed off exposed food or food containers.
