Duty of an ambulance or emergency aid team during any public event is the foundation of people’s safety. The format of the event does not matter: it may be a school assembly, a concert or a sporting event, anyway, you should have medical personnel with all that is needed for the first aid. Somebody can feel sick even during peaceful assemblies because of overheating or undercooling, heartache or pressure rise. Especially it concerns the events where the mixed contingent is present: adults, children, elderly people.
