Most commonly, electric injuries primarily damage the outer limbs, but more critical portions of the body may be affected as well causing severe complications.As the body comes into contact with an electrical source, it becomes part of the electrical circuit. As such, the current has a point of entry and an exit at two different points on the body. The point of entry tends to be depressed and leathery whereas the exit wound is typically more extensive and explosive. It is hard to accurately diagnose an electrical burn because only the entry and exit wounds are visible and the internal damage is not. Prevention
Basic electrical safety
The following are some examples of unsafe practices which could lead to electric injury (this list is not exhaustive. ):
Using electrical appliances while wet (showering, bathing, etc.) as plumbing is often connected to electrical ground, and wet skin loses much of its resistance. Exception for newer quality appliances intended for the bathroom when not simultaneously showering, bathing, being in a path of water going to plumbing, or touching bare concrete or sheet metal. Standing on a dry carpet or rug is ideal. All power mains outlets should have a wall cover to avoid accidentally touching the electrified sides between the wall and outlet. This is especially important for children, as their small fingers can easily reach into this gap along the sides. Using AC electrical appliances around bathtubs, swimming pools, hot tubs, etc. with the risk that the appliance may fall into the water and cause electrocution.
An electrical burn is a burn that results from electricity passing through the body causing rapid injury. Approximately 1000 deaths per year due to electrical injuries are reported in the United States, with a mortality rate of 3-5%. Electrical burns differ from thermal or chemical burns in that they cause much more subdermal damage. They can exclusively cause surface damage, but more often tissues deeper underneath the skin have been severely damaged. As a result, electrical burns are difficult to accurately diagnose, and many people underestimate the severity of their burn. In extreme cases, electricity can cause shock to the brain, strain to the heart, and injury to other organs.For a burn to be classified as electrical, electricity must be the direct cause. For example, burning a finger on a hot electric steam iron would be thermal, not electrical. According to Joules first law: electricity passing through resistance creates heat, so there is no current entering the body in this type of burn. Likewise, a fire that is ruled to be "electrical" in origin, does not necessarily  mean that any injuries or deaths are due to electrical burns. Unless someone was injured at the exact moment that the fire began, it is unlikely that any electrical burns would occur. Causes
Electrical burns can be caused by a variety of ways such as touching or grasping electrically live objects, short-circuiting, inserting fingers into electrical sockets, and falling into electrified water. Lightning strikes are also a cause of electrical burns, but this is a less common event.
