Electrical Extension Cords Safety Tips

• Extension cords should only be used temporarily, as overloading or improper use can lead to serious fire and shock hazards.

• Always choose the correct cord rating, keep cords dry, inspect for damage, and never run them under rugs or through walls.

• If you rely on extension cords often, installing additional outlets or upgrading your electrical system is the safest long-term solution.

Extension cords are a convenient way to bring power to devices and appliances when outlets aren’t nearby, but they come with safety risks. 

According to the Electrical Safety Foundation International (ESFI), around 4,000 extension cord-related injuries are treated in emergency rooms annually in the U.S., and 3,300 home fires are started by extension cords each year, causing 50 fatalities and 270 injuries. 

By following essential safety tips, you can protect your home and loved ones from these risks.

Key Safety Tips for Using Extension Cords

• Avoid Overloading: Never overload extension cords by plugging in devices that exceed their wattage rating. Check the label on the cord and the appliance for compatibility.
• Keep Cords Dry: Do not allow extension cords to come into contact with water or snow, which can lead to electric shock or fire.
• Temporary Use Only: Extension cords are designed for short-term use. For permanent wiring, contact a licensed electrician to install additional outlets.
• Do Not Cover Cords: Avoid running cords through walls, ceilings, floors, or under rugs, as this can trap heat and create a fire hazard.
• One Cord, One Appliance: Use a separate extension cord for each device to prevent overloading.
• Check the Rating: Ensure the cord is rated for indoor or outdoor use as needed, and that its capacity matches the device’s requirements.
• Inspect Cords Regularly: Do not use cords that are hot, frayed, or have exposed wires. Replace damaged cords immediately.
• Use Grounded Plugs: Never modify a three-prong plug to fit into a two-prong outlet, as this defeats the grounding feature and increases the risk of shock.
• Polarized and Certified Cords: Use cords with polarized or three-prong plugs and ensure they are certified by a recognized safety laboratory like UL, ETL, or CSA.

Common Misuses of Extension Cords

Misusing extension cords is one of the leading causes of electrical fires and injuries. Here are some common mistakes to avoid:

• Using indoor cords outdoors, exposing them to weather damage.
• Chaining multiple power strips together, which can overload circuits.
• Leaving cords plugged in when not in use, increasing the risk of overheating.
• Placing cords in high-traffic areas where they can be tripped over.
• Forgetting to unplug cords when they feel hot to the touch.

What Should Never Be Plugged Into An Extension Cord?

Avoid at all costs plugging in any high-wattage appliances that create heat or have motors e.g. microwaves, space heaters, refrigerators, AC units, power tools, and hair dryers. These require too much power and can overheat, leading to short circuits and even fires.

Alternatives to Overusing Extension Cords

Over-reliance on extension cords often signals a lack of adequate outlets in your home. Consider these long-term solutions:

• Install Additional Outlets: Have a licensed electrician add outlets in key areas of your home to meet your electrical needs.
• Upgrade Your Electrical System: Older homes may have outdated wiring that cannot support modern power demands. Upgrading can improve safety and efficiency.
• Use Surge Protectors: For devices like computers and TVs, use surge protectors instead of basic extension cords to safeguard against power surges.

What to Look for When Buying Extension Cords

Choosing the right extension cord is essential for safety and performance. Here’s what to consider:

• Length: Choose a cord that is the right length for your needs. Longer cords can reduce efficiency and increase the risk of overheating.
• Gauge: The lower the gauge number, the thicker the wire and the more electricity it can safely handle. For heavy-duty appliances, opt for a cord with a lower gauge.
• Certification: Ensure the cord is certified by a trusted safety organization like UL, ETL, or CSA.
• Special Features: Consider cords with built-in circuit breakers for added protection against overloads.

FAQs About Extension Cord Safety

• How often should I inspect my extension cords?
  Inspect cords before each use and replace them if there are signs of damage or wear.
• Can I use an extension cord for heavy appliances?
  Only if the cord is rated for the appliance’s wattage. For high-powered devices, consider a dedicated outlet.
• Are coiled extension cords safe to use?
  No, using a coiled cord can cause it to overheat and potentially ignite.
• What should I do if my extension cord feels hot?
  Unplug it immediately, as this is a sign of overloading or damage.
