Extension Cord Hazards & Proper Use

Feb 24, 2016 | Electrical Safety

Understanding Extension Cord Hazards and Proper Use

Extension cords are a quick and convenient solution when you need to power devices beyond the reach of standard outlets. However, improper use can lead to significant extension cord hazards. By ensuring extension cord proper use, you can avoid these dangers and keep your home safe.

Extension Cord Hazards

High-Traffic Areas

Running extension cords across high-traffic areas poses a serious tripping hazard. Loose or hanging cords can easily be tripped over, leading to falls and injuries. Moreover, the force of a trip can disconnect the cord, potentially damaging the devices connected to it. To avoid this, always place extension cords away from pathways and ensure they are secured properly.

Under Furniture or Rugs

It’s tempting to hide extension cords under rugs or furniture to keep them out of sight. However, this practice is extremely dangerous. Over time, extension cords can overheat when covered, leading to a potential fire hazard. The insulation around the wires can degrade faster when subjected to constant pressure and heat, increasing the risk of an electrical fire. Instead, consider running the cord along the baseboards or behind furniture, where it can remain visible and cool.

Securing with Nails or Staples

Using nails or staples to mount extension cords might seem like a good way to keep them in place, but it can be hazardous. These sharp objects can puncture the cord’s protective insulation, exposing the wires inside. This exposure can lead to electrocution if someone comes into contact with the damaged area. It’s safer to use clips or other devices specifically designed to hold extension cords without damaging them.

Connecting Multiple Cords

Avoid plugging one extension cord into another, a practice known as daisy-chaining. This reduces the electrical capacity and can lead to devices not receiving sufficient power. Daisy-chaining can also increase the risk of overheating and electrical fires because the combined length of the cords often exceeds the safety limits of the wires. Always use a single, longer extension cord or install additional outlets to meet your needs.

Outdoor Use

Only use extension cords rated for outdoor use when operating outside. Indoor extension cords lack the durability to withstand outdoor conditions, such as moisture, temperature fluctuations, and physical wear. Outdoor extension cords are designed with thicker insulation and are more resistant to environmental factors, reducing the risk of electrical shock and fire.

Electrical Load

Every extension cord has a specified electrical load capacity, usually indicated on its packaging or the cord itself. Overloading an extension cord by plugging in devices that exceed this capacity can lead to overheating and fire hazards. It’s crucial to calculate the total wattage of all devices connected to the extension cord and ensure it does not exceed the cord’s rating. If in doubt, consult an electrician or use a power strip with an integrated circuit breaker.

Storage

Proper storage of extension cords is essential to prolong their lifespan and maintain safety. When not in use, unplug them by holding the plug (not the cord) and store them indoors. Exposure to the elements can cause cords to crack and deteriorate, leading to potential electrical hazards. Coiling the cords neatly and storing them in a dry, cool place will help maintain their integrity and readiness for future use.

Three-Prong Cords

Three-prong extension cords are designed with a grounding prong for added safety. Forcing a three-prong plug into a two-prong outlet removes this safety feature, increasing the risk of electrical shock. The grounding prong provides a path for electrical current to safely return to the ground in the event of a fault. Always ensure that the outlets you use are compatible with three-prong plugs, or use an adapter that maintains the grounding feature.

Extension Cord Proper Use

By following these guidelines, you can ensure the proper use of extension cords and minimize potential hazards.

Assessing the Need for Extension Cords

Evaluate your reliance on extension cords. If you frequently use them because of a lack of outlets, it may be time to consider installing additional outlets in strategic locations. This not only enhances convenience but also reduces the risk of overloading extension cords.

Choosing the Right Extension Cord

Select an extension cord that meets the specific requirements of your devices. Consider factors such as length, gauge, and load capacity. Heavier gauge (lower gauge number) cords are suitable for higher load appliances, while lighter gauge cords are better for smaller devices.

Proper Placement and Routing

When placing extension cords, ensure they are routed away from foot traffic and are not pinched by furniture. Use cord covers or protectors if necessary to prevent tripping and damage. Avoid running cords through doorways or windows where they can become pinched or frayed.

Regular Inspection

Regularly inspect your extension cords for signs of wear and tear, such as fraying, cracking, or exposed wires. Replace damaged cords immediately to prevent electrical hazards. Even if a cord appears to be in good condition, check the plug and outlet connections for signs of overheating or burning.

Temporary Use Only

Extension cords are intended for temporary use, not as permanent wiring solutions. If you find yourself using extension cords for extended periods, it’s a sign that you need more permanent electrical solutions, such as additional outlets or new wiring.

Labeling and Organizing

Label extension cords to keep track of their load capacity and intended use. Organizing cords by their purpose (e.g., indoor, outdoor, heavy-duty) helps ensure that you use the right cord for the right job.
