Heat or smoke near outlets, switches, wiring or the electrical panel.
A recurring hot smell should be investigated even when breakers remain on and visible equipment still works. If the correct breaker can be reached safely, switch it off and leave the damaged equipment untouched.
Electrical odors can travel through wall cavities, making the strongest-smelling room different from the source. If there is active fire, heavy smoke or immediate danger, move to safety and call 911 first.
Smoke near service equipment can involve high-current connections that should not be approached or opened. If the correct breaker can be reached safely, switch it off and leave the damaged equipment untouched.
