A thermal burn occurs as a result of direct contact with a heat source. This can include flames, hot liquids, steam, or any other source of extreme temperature. When the skin or other tissues are exposed to these high heat levels, the cells can become damaged, leading to various degrees of burns classified as first, second, or third degree depending on the severity and depth of tissue affected.

In contrast, electrical burns result from an electrical current passing through the body, typically causing internal damage that may not be immediately visible. Chemical burns occur due to the skin's exposure to corrosive substances, such as strong acids or alkalis, which are harmful upon contact. Radiation burns are caused by exposure to radiation sources, such as UV rays from the sun or radiation from medical treatments. Understanding these distinctions is crucial for accurately assessing and responding to different types of injuries in a law enforcement context.
