Extension Cords, Extended Risks: How to Stay Safe
Extension Cord Safety: 7 Tips You Should Never Ignore
Extension cords are everyday essentials—especially when a wall outlet is just out of reach. But while they’re incredibly useful, they also come with potential hazards if not used correctly. Whether you’re plugging in power tools, home appliances, or tech devices, following basic safety tips can help prevent accidents and keep your home safe.
Here are seven essential extension cord safety tips to keep in mind:
1. Only Buy Certified Extension Cords
Before purchasing an extension cord, check for a certification mark from a trusted safety organization like UL (Underwriters Laboratories), CSA (Canadian Standards Association), or ETL (Intertek). These marks indicate the cord has undergone thorough testing for safety and performance. If the packaging doesn’t display one of these labels, it’s best to leave it on the shelf.
2. Choose the Right Size and Length
Extension cords come in different gauges, which refer to the thickness of the internal wiring. A lower gauge number means a thicker wire and more power capacity. Always match the cord’s gauge and length to the job. Don’t daisy-chain multiple cords together—this can cause overheating or even fire. If you need a longer reach, invest in a single, properly rated cord.
3. Match the Cord to the Device’s Power Needs
Check the amp or wattage rating on your appliance or tool and make sure your extension cord matches or exceeds it. Using a cord that’s underpowered for your device can cause overheating and pose a fire risk.
4. Stick to One Device Per Cord
Avoid plugging multiple devices into a single extension cord. Overloading can stress the cord and lead to overheating or fire. If you need more outlets, use a properly rated power strip with surge protection—but don’t go overboard.
5. Never Cover Extension Cords
Extension cords need proper ventilation. Running them under rugs, furniture, or through enclosed spaces traps heat and can result in a fire hazard. Always place them in open, visible areas where heat can dissipate freely.
6. Keep Indoor Cords Indoors
Using an indoor-rated cord outside can be dangerous. These cords aren’t designed to handle exposure to moisture, sunlight, or temperature extremes. If you’re working outside, use a cord specifically labeled for outdoor use, and keep it away from any water sources.
7. Don’t Modify the Cord
Never cut off the grounding prong (the third round pin on a three-prong plug). That prong is there for a reason—it protects both you and your equipment from electrical faults. Altering a cord compromises its safety and can lead to electric shock or damage.
Final Thoughts
Extension cords are meant to be a temporary solution, not a permanent fix. Used with care and according to safety guidelines, they can help you power through all kinds of tasks safely. But always remember: convenience should never come at the cost of safety.
