2. Using an indoor extension cord outdoors

Not all extension cords are specifically designed for outdoor use, unless their packaging clearly states that they are weather and water resistant. If you have a very common extension cord, keep it indoors and buy a more rugged one that you can safely use.

3. Weak sockets but full of  loads

Every extension socket has a load limit. It means that it can only handle a certain amount of power at any one time. When an extension socket is overloaded, it can melt, damaging your home and surrounding appliances as well as creating a fire hazard.

If you are concerned that your extension socket is at risk of being overloaded, calculate the total power of everything you will be plugging into it, or consider buying an extension socket with a separate switch for each plug.

4. Covering the extension socket with something else

When electricity flows through the wire, the electrons generate heat. While normally this isn’t a big deal, if your extension cord is hidden under a rug or in a confined space, it could pose a fire hazard.

Additionally, if you accidentally step on it, you could damage not only the cord itself but also the appliances plugged into it, and you could also get an electric sh0ck.

5. Plugging Beauty Tools Into the Same Extension Socket

Curling irons, straighteners, hair dryers, and other beauty tools all generate heat and use a lot of electricity (high amperage) to generate that heat. Regular extension sockets are not designed to handle this kind of high-current intensity, so it’s advisable to plug these beauty tools into a wall outlet protected by a ground fault circuit interrupter (GFCI).
