Electric blankets: lay it flat, leave it uncovered, plug it into the wall and retire the old ones

The five-minute look

Spread the blanket out flat in good light and check both sides. [S1] [S4]

• Spots. ESFI says to look for dark, charred or frayed spots. UL Solutions, citing the Maine State Fire Marshal, adds worn areas and charred spots on both sides. [S1] [S4]
• Cord, plug and connectors. Look for a cord that’s cracked, frayed or cut, a loose plug, and cracks or breaks in the wiring, plugs and connectors. [S1] [S3] [S4]
• Age. ESFI says almost all electric blanket fires involve blankets more than ten years old, and to replace any worn or old one. [S1] [S2]
• Lab mark. ESFI wants a blanket certified by an independent testing lab such as UL, CSA or ETL, and bought from a reputable retailer. UL Solutions says never to buy one secondhand or at a garage sale. [S1] [S3] [S4]

A clean look isn’t the whole story. Fairfax County Fire and Rescue points out that there’s no way to inspect a blanket for internal damage. If you have any doubt, stop using it as an electric blanket; it still works as a regular blanket unplugged. [S5]

Check it against recalls

Recalls aren’t rare. In September 2026, CPSC announced a recall of about 195,000 JKMAX heated blankets and heating pads because the internal heating wires can overheat. JKMax knew of 577 reports of blankets smoking, melting or burning, including 53 burn injuries. They were sold online from September 2022 through July 2026. [S6]

In 2023, about 350,000 Bedsure heated blankets and pads were recalled because the controller can malfunction, after 137 reports of fires, burning, melting or overheating and 17 reports of burn injuries. [S7]

• Find the model number. On the recalled JKMAX units it’s on the back of the remote and on the packaging label. On the Bedsure units it’s on a white label on the back of the blanket and on the back of the controller. [S6] [S7]
• Search it. CPSC’s recall list updates weekly, and you can sign up for recall emails there. [S8]
• If it matches. Stop using it right away and follow the recall’s remedy; both recalls above offer a refund. [S6] [S7]
• If something went wrong. CPSC asks you to report an unsafe product on SaferProducts.gov. [S8]

Flat, uncovered, alone

Most of the rules come down to heat that can’t escape. ESFI says never fold an electric blanket while it’s on, because a folded or tucked-in blanket could overheat. When it’s covered by anything, including other blankets or pets, it may overheat too. [S1] [S2]

• Don’t tuck it in. ESFI says not to tuck it under the mattress or under children. [S1] [S3]
• Nothing piled on. No comforters or bedspreads on top while it’s on (ESFI), and no toys, pillows or stuffed animals (Fairfax County). [S3] [S5]
• Don’t sit or lie on it. Fairfax County says that can damage the internal coils. Pets shouldn’t sleep on it either, and UL Solutions notes they can chew the wires. [S3] [S4] [S5]
• One heat source. ESFI says heated pads that go on the mattress and electric blankets aren’t meant to be used at the same time. UL Solutions says heat can get trapped between the layers and cause burns. [S1] [S4]
• Right bed. UL Solutions says never use one on a sofa bed, pullout bed or adjustable bed, where the wires could be pinched or frayed. [S4]

The cord and the outlet

• Wall outlet. ESFI says not to plug an electric blanket into an extension cord or power strip, because it could overheat and cause a fire. Our space heater outlet guide covers the same rule for heaters. [S1]
• Keep the cord in the open. UL Solutions says never to run it between the mattress and box spring, under a rug, or where a bed frame, wall, slat or footboard can pinch it. Don’t staple or pin it to a wall. [S4]
• Off and unplugged. When you’re done with it, turn it off and unplug it. [S4] [S5]

Warm the bed, then switch it off

ESFI says heating appliances should never be left unattended or used while sleeping. A burn surgeon quoted by UL Solutions gives the practical version: turn the blanket on about half an hour before bed and switch it off before you climb in. [S1] [S4]

He says burns usually happen when someone falls asleep on a bunched-up area of the blanket, so heat sits on the same part of the body for a long time. [S4]

If you ever see smoke or discoloration, unplug it. Fairfax County says discoloration means it’s burning inside. A working smoke alarm is the backup; our smoke alarm chirp guide covers what its chirps mean and when to replace one. [S5]

Who should skip it

UL Solutions says people with diabetes are more vulnerable to burns from electric blankets because they may be less sensitive to heat. Electric blankets also aren’t recommended for infants, young children, or anyone who is paralyzed or can’t understand how to use one safely. People with urinary incontinence shouldn’t use them. [S4]

If that’s someone in your home, ask their doctor first.

Washing and storage

UL Solutions says to follow the maker’s directions for cleaning and storage. Store the blanket rolled, not folded. [S4]

Washing is where the sources disagree; see the box below. Go by the care label on your blanket. [S4] [S5] [S6]
