Skin is the largest organ of the human body. It has billions of neurons that signal to our brain when it is hot, cold or injured. With relatively minor burn injuries, referred to as first-degree burns, we generally run water on the area to soothe the pain and maybe use a minor pain reliever or aloe vera. The outer layer of skin regrows and heals with minor scarring. When burned more severely, the skin's lower layer permanently injured, which is considered a second or third-degree burn.

Electrical injuries result from electricity exposure and can cause severe exit wounds. Clothing fires are dangerous as it can spread quickly and cause grievous injury. USA branded clothing must comply with the Flammable Fabrics Act. Thermal burn injuries occur when there is exposure to flames, steam, flashes, surfaces, and liquids exceeding 115 degrees. Automobile fires and gas explosions may result from auto accidents. Laboratory chemicals that dissolve skin are difficult to wash away after exposure. Fires are a common cause of residential or office injuries and deaths.

Severe burn injuries can destroy skin elasticity, sense of touch and the ability to perspire. Healed skin might also require constant protection from the natural elements.
