It is composed of three layers, with each layer performing specific functions. The skin is the largest organ of the body and has many important functions. The human body cannot dissipate the heat generated by current flowing through the resistance of the tissue and therefore burns occur. They occur when electric current flows through tissue or bone, generating heat that causes tissue damage. The severity of a burn depends on how deeply it has affected the tissue.Įlectrical burns from electric current, either alternating current (AC) or direct current (DC), are among the most serious burns and require immediate medical attention. For example, the airways and lungs can be damaged as a result of inhaling hot fumes and gases. ![]() Burns can also be caused by chemicals, electricity, the sun’s rays, friction (rubbing or chafing) or extreme cold.īurns usually affect the skin, but other important areas of the body can also be injured. ![]() This can be direct contact with fires, radiators or hot liquids, but also the radiated heat from an extreme source of heat, such as a furnace or open fire. Apart from direct fire, heat, in its different forms, represents significant danger and is the most obvious cause of burn injuries. Recognising different types of burns and having a basic knowledge of how to treat them can minimise injury and prevent fatalities.
