One would be surprised to hear how many injuries are caused by electrical outlets. Individuals need to regularly check electrical outlets and plugs for tell-tale signs of fire or wiring issues. Any faulty plugs (such as plugs with exposed wires) should be replaced immediately. One very obvious sign that an outlet needs an immediate check-up is the discolored spots around outlets. According to the National Fire Protection Association, a discolored wall outlet can be caused by “arcing, smoldering, burning happening behind your outlets, damaged or improperly installed wiring in the outlet, or a problem with the receptacle itself.”
            Another thing that one should look out for is the tingling sensation when plugging appliances. Sometimes you cannot see the signs of a problem with an electrical plug or outlet; instead, you will be able to smell, feel or hear the issue. In any case, we would recommend checking with licensed electricians.
