Thermal burns—These types of burns occur when you touch something hot.
The most common thermal burn injuries come from:
1.1 Fires or open flames;
1.2 Hot objects, such as grills, griddles, pans, engines, and appliances; and
1.3 Hot liquid or steam.
2 Chemical burns—Chemical burns are caused by exposure to a chemical irritant, such as chlorine, ammonia, battery acid, bleach, or harsh cleansing agent.
3. Electrical burns—Exposure to unprotected electrical current can damage internal and external tissue.
4. Friction burns—A friction burn happens when your skin makes repeated contact with an unlubricated surface. Most friction burns happen when a body part is dragged along a surface, but some repetitive motions also can cause friction burns.
