What to do if…
an extension cord or power strip becomes hot, soft, or discoloured while in use

Short answer

Stop using it immediately. If it’s safe, unplug it from the wall (or turn off the breaker first) and keep it out of service.

Do not do these things

  • Don’t keep using it because “it still works.”
  • Don’t plug it back in to test whether it gets hot again.
  • Don’t handle softened/melted plastic or any exposed metal with bare hands.
  • Don’t “repair” it with tape, glue, or a replacement plug if the cord/strip itself overheated.
  • Don’t plug a power strip into another power strip or into an extension cord (daisy-chaining).
  • Don’t run cords under rugs/carpets, through doorways, or under furniture.
  • Don’t use a power strip/extension cord for high-draw appliances (commonly space heaters, microwaves, air fryers, toasters, window AC units).
  • Don’t treat extension cords as permanent wiring.

What to do now

  1. Make a safer pause. If you smell burning, see smoke, hear buzzing/crackling, or see melting/discoloration, move people and pets away from the area.
  2. Cut power safely (pick the safest option):
    • Best: Turn off the device(s) using the strip, then unplug the strip/cord by holding the plug (not the cord).
    • If the plug/outlet looks scorched, is sparking, or you feel unsafe getting close: go to your electrical panel and switch OFF the breaker for that outlet/area (or the main breaker if unsure).
  3. If there’s active fire or heavy smoke, escalate. Get to a safer location and call 911.
  4. Let it cool on a non-combustible surface. After power is off, place the cord/strip on tile/stone/metal away from paper, curtains, bedding, and upholstery. Don’t touch damaged areas while it cools.
  5. Take it out of service. If it became hot to the touch, soft, or discolored, treat it as unsafe:
    • Mark or bag it “DO NOT USE” so nobody plugs it in again.
  6. Prevent repeat overheating today (simple, practical checks):
    • Check the rating label on the cord/strip and avoid using it for anything near its limits. If you can’t find a rating, treat it as “unknown” and don’t reuse it.
    • Move any high-draw appliance (especially space heaters) to a wall outlet directly.
    • If you needed the strip because you “don’t have enough outlets,” treat that as a sign to add proper outlets—don’t keep stacking strips/cords.
  7. Treat outlet warning signs as a fixed-wiring problem. If the wall outlet or plug was hot, loose, discolored, buzzing, or smelled burned, keep that outlet off at the breaker and contact a licensed electrician. If you rent, notify your landlord/property manager as an urgent electrical safety issue.
  8. Check for recalls and replace safely. Look up the brand/model for CPSC recalls. When replacing, choose a product that’s appropriately rated and safety-certified (commonly listed by a recognized testing lab such as UL/ETL).
  9. If anyone is injured or feels unwell, get medical help. Burns, electrical shock symptoms, or smoke inhalation symptoms warrant urgent care; call 911 for severe symptoms.

What can wait

  • You don’t need to diagnose the exact cause right now.
  • You don’t need to do detailed wattage math immediately.
  • You don’t need to decide today about electrical upgrades—just keep the unsafe item out of service and keep any suspect outlet off.

Important reassurance

Heat, softening, or discoloration is a clear warning sign—not something to “watch and see.” Unplugging and stopping use quickly is the right action and meaningfully lowers fire and shock risk.

Scope note

These are immediate first steps to reduce harm and prevent repeat use. Follow-up (replacement choices, electrician inspection, landlord/insurance steps) can happen once everything is stable.

Important note

This is general safety information, not professional electrical advice. If you suspect outlet or wiring damage, keep the breaker off for that area and get a licensed electrician. In an emergency with fire, smoke, or immediate danger, call 911.
