Electrical fires can be caused by a breakdown or malfunction in the electrical components of equipment or machinery. Electrical fires start in wires, cables, circuit breakers, and electrical components. Overloaded circuits or the age of the panel cause fires in electrical panels. Short-circuited power tools, motors, and other electrical equipment can also start electrical fires.
Fires can also be started by external sources such as electricity from a pole or another source through a person who touches both live and dead parts of an electric circuit. This type of fire is called a "contact" fire because of the way it starts. External contact with high voltage lines can also lead to injuries such as amputation if not done properly. Contact wiring should never be used for anything other than temporary work sites, such as construction projects, because it is easy to accidentally cut off the power which stops the fire before you know it is starting.
Contact wiring is usually colored red to indicate that it must never be used on permanent jobsites where power outages could be dangerous. If contact wiring is used on temporary jobsites, then it should always be taped off initially in order to identify any problems before they become disasters.
Short circuits cause fires when current passes along a path of less resistance instead of through its intended destination. A short circuit can happen when two pieces of conductive material connect together across a gap too small to allow current to pass normally.
When the distribution of power is insufficient, the panel and circuits become overloaded. This can lead to fire damage unless the panel is replaced.
Fire starts in wiring usually near outlets and light switches because these are the first things people use when getting out of bed or coming into a room. If a piece of wire gets hot enough it will always find a way to ground itself. The more conductors there are within reach of their potential, the better chance there is of finding something to ground itself to. For example, if you have three conductors running to the switch, and one of them goes bad, it's much more likely that line will get hot than if only one conductor were used.
The best way to avoid electrical fires is to make sure all metal objects are well grounded. If you are working with electricity, all metallic objects should be considered dangerous until they are confirmed as non-conducting materials by a qualified professional.
Electricity is not dangerous unless you allow it to be by doing something stupid like sticking your hand into an outlet socket. Any object that allows current to flow through it is capable of starting a fire.
Appliances and outlets that aren't working Faulty electrical outlets and old, outdated equipment are the most common causes of electrical fires. Faults in appliance wires, receptacles, and switches create other fires. Another source of electrical fires is the usage of extension cables under carpets. These cables can cause flames to jump from room to room if they're not properly installed.
Household fires caused by electricity are responsible for nearly half of all residential fire deaths. Electrical fires can spread rapidly because they can happen anywhere in the home where there's a conductive surface - such as inside walls or ceilings. The best way to prevent an electrical fire is to never touch any metal part of your house with wet hands or tools. If you do get water on a metal part of your house, immediately dry it off with a clean cloth before reentering your home.
If you experience a fire in your home, check for heat damage. If you see light bulbs exploding everywhere, then you probably have a serious problem. Call the police and tell them what location you saw the fire so they can mark it off their map. You should also call your insurance company after an incident occurs. They may need to file a claim with your carrier to receive increased coverage for future incidents.
