A friction burn occurs when the skin is dragged or run against a surface with some degree of resistance. The resistance generates friction, which generates heat.
General causes of friction burn:
(1) sliding or being dragged across any rough surface with inherent resistance
(2) grabbing or brushing against anything moving
Specific causes of friction burn:
(1) a rope
(2) belt or rotating sander
(3) motorcycle or bicycle accident
(4) being dragged behind a car or truck
(5) treadmill or other excercise equipment
(6) fan belt
Potential hazards of a friction burn:
(1) thermal burn which can range from first to fourth degree
(2) skin abrasion and trauma from contact with the surface
(3) infection, including risk of tetanus
(4) concurrent trauma (fracture, joint dislocation, etc)
