Outdoor music festivals (OMFs) generate significant interest for environmental health professionals (EHPs). There is sufficient evidence to indicate that OMFs are associated with an increased risk to health and safety. A considerable proportion of these risks has been attributed to crowd behaviour in the general admission or 'mosh pits'. Consequently, managing the impact of crowd behaviour in these areas would have a positive impact on the safety and success of these OMFs. Improving the quality of planning, and subsequently event management, was highlighted as the best method to deal with crowd related risks. EHPs are in a position to influence the event planning processes through their involvement in local government event licensing programs. This article is based on the findings of an extensive literature review and was intended to encourage EHPs to have further participation in crowd management for OMFs.
