Responsibility for the preparation and implementation of such guidelines is a matter for each National Governing Body (NGB) concerned. Different sports have different public liability risk profiles reflecting the specific characteristics of that sport.
NGBs are accordingly best placed to consider and decide upon the optimum risk mitigation and reduction measures to deploy in order to enhance participant safety, minimise risk and reduce insurance costs. Further information on the guidelines currently in place is available from the websites of the sports in question.
