The risk of injury from moshing and crowd surfing at music festivals and concerts is well documented. Moshing involves close physical contact  in the front of house area in front of a band: "the mosh pit."  Participants in the mosh pit push, pull, shove, slam  and bounce off one another  to the music.  Crowd surfing involves passing audience members above the heads of other moshers toward the stage. Since 2000 moshing has been becoming increasingly less popular amongst public venues and music festivals because of its high risk of injury, and not without due cause.  A study in 2000 conducted at a 4 day music festival, attended by over 60,000 people found that over 1,500 medical incidents were reported during the festival.  The festival encountered numerous incidents resulting from moshing, crowd surfing and stage diving.  37 % of all incidents related directly to moshing.  2.5% of all treatments required hospital transporting, and of those, 74% were mosh pit related. (American Journal of Emergency Medicine 2000;18:62-63). These statistics demonstrate the importance of strictly enforced risk management plans relating to the event and stage floor layout, and close consideration of the type of acts who are performing.  It also highlights the importance of carefully planned medical care that is commensurate on the expected injury types and numbers.
