Which practice would NOT help prevent electrical fires in homes?

• A. Using daisy-chained extension cords
• B. Replacing damaged cords
• C. Avoiding overloading outlets
• D. Having electrical work done by a professional

Answer: (A)

Using daisy-chained extension cords would not help prevent electrical fires. Extension cords are meant for temporary, lightweight use, and plugging one cord into another creates a longer cord with more connection points. Each connection can loosen or overheat, and longer cords heat up more under load, especially when high-wattage devices are involved. Damaged cords or cords routed improperly can also fray insulation and increase the risk of arcing. Replacing damaged cords directly reduces a common fire hazard by restoring safe insulation and reducing resistance at the cord’s surface. Avoiding overloading outlets helps keep heat from building up in cords and outlets, lowering the chance of overheating. Having electrical work done by a professional ensures wiring and outlets are correctly installed, up to code, and properly grounded, which minimizes risks of overheating, arcing, and faulty connections.
