Which of the following is a common electrical fire hazard found in homes?

• A. Gas leaks
• B. Loose doorknobs
• C. Overloaded outlets/extension cords
• D. Carbon monoxide alarms

Answer: (C)

Overloaded outlets and extension cords create a direct electrical fire risk because circuits have a finite capacity to carry current, and heat builds up when that limit is exceeded. Cords and power strips aren’t designed for continuous high-wattage use, so plugging many devices or high-draw appliances into one outlet can cause insulation to overheat, leading to arcing or ignition of nearby combustibles. Signs of danger include outlets that feel warm, flickering lights, or frequent breaker trips.

To stay safe, avoid daisy-chaining cords or using extension cords as permanent wiring, especially for heaters, microwaves, or hair dryers. Use dedicated outlets for high-draw appliances, inspect cords for fraying or damage, replace damaged cords, and unplug devices when not in use. Keep cords away from rugs and furniture, and use quality surge protectors with proper rating. Other choices relate to non-electrical hazards (gas leaks, carbon monoxide monitoring) or different types of risks, not the common electrical fire hazard described here.
