What to do if…
you smell burning plastic or see scorching around an outlet or switch

Short answer

Assume an electrical overheating/fire risk: stop using that outlet/switch and turn off power at the breaker panel if it’s safe. If there’s smoke, flames, or sustained sparking, get out and call 911.

Do not do these things

  • Don’t keep plugging things in to “check” it, or keep flipping the switch.
  • Don’t keep resetting a breaker or replacing a fuse that trips again.
  • Don’t touch a hot outlet/switch plate, melted plastic, or exposed metal.
  • Don’t remove the cover plate or try to look “behind” the outlet/switch.
  • Don’t use water on it or try to cool it with anything wet.
  • Don’t attempt a DIY fix if you’re not trained and equipped.

What to do now

  1. Check for immediate danger. If you see flames, smoke, or ongoing sparking: leave immediately, close doors as you go, and call 911.
  2. If it’s safe, shut off power at the breaker panel. Turn OFF the breaker for that room/circuit.
    • If you can’t identify the correct breaker quickly, switch OFF the main breaker.
  3. If the breaker trips again, leave it OFF. Don’t keep trying to reset it.
  4. Unplug devices only if it’s safe. If the plug is hot, stuck, or the outlet face is melted/scorched: leave it and keep power off.
  5. If it seems tied to one plug-in item (charger/appliance/power strip/extension cord): keep that item unplugged and don’t use it elsewhere. Once it’s cool, set it on a non-combustible surface away from anything that can burn.
  6. Clear the area and (once power is off) document the damage. Move paper/curtains/chargers away from the outlet/switch. Take a quick photo and note which breaker you turned off (helps an electrician/landlord).
  7. Call a licensed electrician promptly. Say you had a burning plastic smell and scorch marks/heat at an outlet or switch and the circuit is currently off.
  8. If you rent (apartment/condo): notify your landlord/property manager right away. Tell them you’ve shut off the breaker and that the outlet/switch shows scorching/overheating.
  9. If the smell/heat seems to come from the breaker panel, meter base, or service equipment: don’t touch the equipment. If there’s heat/smoke, evacuate and call 911. If there’s no immediate fire but you suspect service equipment involvement, contact your electric utility for guidance.

What can wait

  • You do not need to pinpoint the exact cause right now.
  • You do not need to turn power back on to “see if it stopped.” Keep it off until inspected.
  • You do not need to decide on permanent repairs or insurance paperwork in the moment—focus on making it safe.

Important reassurance

This is reasonable to take seriously. Discoloration/scorching and burning or rubbery smells can be warning signs of overheating connections or wiring, and turning off power and getting help is the right kind of cautious.

Scope note

This covers first steps only. A licensed electrician can determine whether the outlet/switch, wiring, breaker, or a connected device caused the overheating and what must be replaced or repaired.

Important note

This is general information, not professional electrical advice. If there’s smoke, flames, or you feel unsafe, leave and call 911.
