X11: Contact with hot tap-water

Contact with hot tap-water refers to a group of injuries typically caused by exposure to excessively hot water from a tap. This group of conditions primarily affects the skin, causing varying degrees of burn injuries. The severity of these injuries can range from superficial first-degree burns, which affect only the top layer of the skin, to more serious second-degree burns damaging deeper layers. The injuries are generally characterized by red, painful skin that can swell, blister, or peel. In severe cases, they can even affect deeper tissues leading to third-degree burns, which are identified by white or charred skin. Symptoms may appear immediately after contact with hot water, or develop over the following hours. The affected area can also be susceptible to infection, given the breached skin barrier. Such injuries occur more commonly in kitchens and bathrooms, and accidental exposure is most common among children and older adults.
