An outlet sparked or smells like burning. What should you do?
Put safety before diagnosisDo not touch, unplug or switch equipment that is hot, smoking, arcing, wet or visibly damaged; do not open an outlet or electrical panel.
Move people away and stop using the outlet and connected equipment. If there is smoke, flame, active arcing, spreading heat, an electric shock or any doubt that you can remain safely, leave and call emergency services from a safe location. Do not touch the outlet, plug, faceplate or panel to investigate.
When no immediate emergency is present, keep the outlet unused and arrange a qualified electrical inspection. A spark or odor can have more than one source, so its location, timing and associated appliance are useful observations—not a remote diagnosis or permission to reset, remove or repair anything.
Separate immediate hazards, affected circuits and project scope
Which situation best matches the home?
The event occurred when one device was used
The device, cord, plug, outlet or circuit may be involved; the association does not identify which.
Notice next: Report the device and timing without reconnecting it.
Odor, crackling or discoloration remains at the outlet
CPSC and NFPA materials treat these as warning signs for qualified inspection.
Notice next: Keep it unused and describe visible signs from a safe distance.
Safe observation
What should you record before the call?
A short, factual description helps the next professional choose the right first inspection without treating a symptom as proof.
Do not touch-test heat, remove a faceplate or energize the circuit to reproduce the event.
What to record
- Smoke, flame, spark, odor, sound, heat or shock observed.
- Outlet location and device in use at the time.
- Whether water, recent work or physical damage is present.
- Whether other lights or outlets changed at the same time.
Stop and get appropriate help
- Smoke, flame, active arcing or heat is increasing.
- Anyone received a shock or has a burn or other symptom.
- Water, damaged service equipment or an unknown energized surface may be involved.
Short answers
Questions people ask before the call
Can I unplug the device?
Not if the plug, outlet or cord is hot, smoking, arcing, wet or damaged. Move away and use the emergency path when conditions are unsafe.
Does one spark prove bad wiring?
No. It is a warning observation, not a cause diagnosis.
Can I remove the outlet cover to look?
No. Leave inspection of wiring and energized parts to a qualified electrician.
Where this guidance applies
The safety and observation sequence on this page is general U.S. guidance.
Adopted electrical code, permits, inspections, contractor licensing, utility ownership, rental responsibility, prices and provider availability must be checked for the exact property.
A ZIP helps identify possible electrical service areas and utility territories, but it does not prove jurisdiction, address-level coverage or an available qualified electrician.
