<unk>  on hand An<unk>  is a burn that results from electricity passing through the body causing rapid injury. Approximately 1000 deaths per year due to<unk>  injuries are reported in the United States, with a mortality rate of 3-5%.<unk> s 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,<unk> s 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<unk> , electricity must be the direct cause. For example, burning a finger on a hot electric steam iron would be thermal, not<unk> . According to Joule's 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<unk> " in origin, does not necessarily mean that any injuries or deaths are due to<unk> s. Unless someone was injured at the exact moment that the fire began, it is unlikely that any<unk> s would occur.
