An evacuation plan will thus be “critical” in saving lives, by getting a large number of people out of a particular venue in the shortest amount of time, said Dr Graham Ong-Webb, a research fellow at the Institute for Defence and Strategic Studies at the S. Rajaratnam School of International Studies (RSIS). He emphasised that it would be crucial to communicate this plan before the start of the event. This could be done by informing concertgoers the location of exit and emergency points, such as through a video or public announcement. “It will give the concertgoer the requisite information to act on, should something happen,” he said.
