Why Are Extension Cords A Safety Hazard?

Extension cords are often used in homes and businesses to easily extend an electrical outlet’s reach. However, extension cords can also be a safety hazard if they are not used properly. Here are some reasons why extension cords can be dangerous:

  • Extension cords can overheat and start fires.
  • Extension cords can be a trip hazard.
  • Extension cords can be chewed on by pets or children, which can cause electrocution.
  • Extension cords can be damaged by weather, vermin, or physical movement, which can lead to electrocution.

If you must use an extension cord, choose one rated for the amount of electricity you will be using, and do not overload it. Also, keep extension cords away from high-traffic areas to reduce the risk of trips and falls. Finally, always unplug extension cords when you are finished using them.

Selecting Extension Cords

The first step in safely using extension cords is to select the right cord for the job. Not all extension cords are created equal! Some are only meant for indoor use, while others can be used indoors and outdoors. Be sure to check the cord’s labeling before you purchase.

  • Indoor extension cords are typically made of lighter-gauge wire than outdoor extension cords. This is because they don’t need to be able to handle as much electrical current. Indoor extension cords are also typically not weather-resistant, so they should never be used outdoors.
  • Outdoor extension cords are made of heavier-gauge wire than indoor extension cords. This is because they need to be able to handle more electrical current. Outdoor extension cords are also weather-resistant, so they can be used in any weather.

When selecting an extension cord, you should also consider the following factors:

1. Approved By An Independent Testing Laboratory

When shopping for electronics, it is important to be aware of the potential dangers posed by faulty or counterfeit cords. In some cases, these cords can overheat, posing a fire hazard. In others, they may not provide enough power to operate the device properly.

As a result, purchasing cords from a reputable source and checking that an independent testing laboratory has approved them is always advisable. Taking these precautions can help ensure that your electronics are safe and that you get the most out of your investment.

2. Use Extension Cords That Are Marked For Outdoor Use

Working on outdoor projects can be dangerous if the proper precautions are not taken. One of the most important safety measures is using extension cords marked for outdoor use. These cords are designed to withstand exposure to the elements.

They have a higher rating for insulation and weather resistance. as a result, they are less likely to suffer damage that could cause electrical shocks or fires. Furthermore, outdoor extension cords are typically brighter in color, making them easier to spot in grass or underbrush. Using the proper type of cord can help ensure your safety and the successful completion of your project.

3. Make Sure That It Is Rated To Handle The Wattage Of The Devices

Using the correct type of cord is critical to ensuring the safe operation of any electrical device. The gauge of a cord indicates its size, with smaller numbers indicating thicker wires that can safely handle more electrical current.
