New Air Quality Guidelines for Holding OV Events Orienteering Victoria has published new Air Quality Guidelines for Holding Events. These are applicable for all event types, but contain additional actions for Park Street events. They also include the appropriate communication actions. The Guidelines align with those used by the Australian Institute of Sport for outdoor exercise, and are being used by Orienteering Australia. All event organisers and series coordinators should ensure they read and follow these Guidelines. They have been added to the Organising Events page. These Guidelines take effect immediately (January 20 2020). Air Quality Guidelines for Holding Events Click Here Share this
