Introduction
A live event is a temporary concentration of people, infrastructure, electrical systems, security personnel and commercial activity.
The organiser's legal responsibility therefore extends far beyond the performance.
Risk Assessment
Organisers should consider crowd density, entry and exit routes, fire safety, weather, electrical equipment, medical emergencies and emergency evacuation.
These should be documented rather than treated as informal operational assumptions.
Venue and Contractor Responsibility
An organiser may engage a venue operator, security contractor, caterer or event manager. Such contracts should allocate responsibilities clearly.
However, outsourcing a function does not necessarily eliminate the organiser's responsibility to exercise reasonable oversight.
Insurance
Public liability and event insurance can provide financial protection, but insurance is not a substitute for proper safety planning.
Conclusion
Event safety should be treated as a legal compliance function as much as an operational function.
A professionally organised event is one where foreseeable risks were identified before the audience arrived and where responsibility for responding to those risks was clearly allocated.
