Most extension cord fires are avoidable.

Yes, but it’s almost always misuse, not a manufacturing defect.

The big three causes: running too much current through a cord that’s too thin (overloading), damaged insulation (cuts or cracks letting moisture in or wires touch), and pinching the cord under furniture or rugs (traps heat and wears the jacket).

Inspect by looking, not guessing. Unplug the cord and run your fingers along the full length. Feel for cuts, kinks, or soft spots. Check both ends—bent prongs or a loose plug means replace it. If the cord feels warm to the touch while in use, you’re overloading it. Don’t daisy-chain power strips or use indoor cords outdoors even for “just a minute.”

If you see any damage, throw it away. Cords are cheap. Fires are not.
