Extension Cords— Small Cord, Big Risk
Did You Know?
Extension cords in the U.S. may contain lead in their plastic insulation, which is why they often carry California Proposition 65 warnings. [2]
KNOW THE RISK
- Extension cords can cause fires or electrical shock when used improperly. Overheating is a common and dangerous outcome of misuse. [1]
- Roughly 3,300 home fires are caused by extension cords each year, resulting in dozens of deaths and hundreds of injuries. [1]
MITIGATE THE RISK
1. Never Use an Extension Cord While Coiled or in a Tight Bundle
- Coiled cords generate heat quickly, especially when powering high-wattage devices. Always unroll cords fully before use. [1]
2. Avoid “Daisy Chaining” Extension Cords
- Plugging one extension cord into another increases resistance and heat, which can lead to electrical fires. Use a cord of adequate length and rating instead. [1]
3. Never Cover an Extension Cord or Use it in a Wall or Ceiling
- Cords covered by rugs, furniture, or walls can trap heat, creating a serious fire hazard. Extension cords should always remain visible and well-ventilated. [1]
ELECTRICAL SAFETY REMINDER
Extension cords are meant for temporary use — not permanent wiring. Choose the right cord for the job, don’t overload it, and always watch for signs of overheating. It’s a simple way to avoid a devastating fire.
