X10-X19: Contact with heat and hot substances

X17: Contact with hot engines, machinery and tools

Contact with hot engines, machinery, and tools belongs to a group of conditions that are essentially burns and related skin damage caused by high temperatures. These conditions most commonly occur in industrial settings, vehicle accident scenarios, or at home when handling heated machinery or tools improperly. The main cause is direct skin contact with an extremely hot surface or component. These injuries can vary greatly in severity, from minor superficial burns that affect only the top layer of skin to deep second-degree or third-degree burns that cause damage to deeper tissues or underlying muscles. Symptoms often include redness, swelling, pain, and in severe cases, blistering or charring of the skin. Over time, depending on the severity and with proper care, these burns may heal with minimal scarring, or they may lead to significant tissue damage and extensive scarring. The primary systems affected by such conditions are the integumentary system (skin), underlying musculoskeletal systems, and occasionally the nervous system if there is significant nerve damage.
