Blue sparks are usually harmless
If you see sparks coming from your electrical panel, it is usually a sign of an electrical problem and can be dangerous. In some cases, it can lead to an electrical fire. However, if you see blue sparks when plugging or unplugging a cord, this is usually harmless.
Blue sparks are ordinary electrical sparks and are typically nothing to worry about. They occur when electricity flows from the outlet to the metal prongs of the electrical cord when the cord gets close to the outlet. This happens most often when the appliance's circuit is already open and ready to draw power. As long as the sparks are blue, you don't need to call an electrician.
However, if you see sparks of any colour coming from the electrical panel itself, you should immediately turn off the main circuit breaker and call a licensed electrician. Do not attempt to open the panel and inspect the wiring yourself unless you have the proper experience and tools. An electrical panel that is sparking will likely need to be replaced by a professional.
If you see sparks coming from an electrical outlet, it could indicate a more serious issue, such as faulty wiring or moisture in the outlet, which can pose a safety hazard. In this case, you should contact a licensed electrician to inspect the outlet and identify the source of the problem. To prevent further sparking, it is recommended to interrupt the flow of electricity at the circuit breaker.
To prevent electrical panels from sparking, regular maintenance is key. During a preventative maintenance inspection, an electrician can check for signs of damage, such as faulty wiring, loose screws, corrosion, and improperly sized breakers. This can help identify issues early on and reduce the risk of electrical fires and other accidents.

Yellow or white sparks are a cause for concern
If you see sparks coming from your electrical panel, it is likely that there is an issue with the electrical circuit, and it may need to be replaced. Electrical panels distribute power to the rest of the electrical circuits in your home. Therefore, a problem with the panel can affect the whole house and pose a danger to everyone, including the structure of the home.
If you see yellow or white sparks, this could indicate a serious problem. Ordinary electrical sparks are a pale blue colour. If the sparks you are seeing are yellow or white, it could mean trouble. A burning smell accompanying the sparks is a symptom of a hot outlet, which can quickly become a fire hazard. A hot outlet can cause an electrical fire, which research shows accounts for 67% of house fires.
If you see sparks, you should first turn off the appliance, and then the circuit involved in the sparking. If there is another person nearby, ask them to monitor the appliance or turn off the circuit breaker. You should then unplug the appliance from the affected outlet. This will allow any electricity in the appliance to discharge, and reduce the chance of a fire spreading. You can then take a closer look at the appliance to determine the cause of the sparking.
If you are unable to identify the cause of the sparking, you should call a licensed electrician to inspect the wiring.
