How far in advance should event coordinators announce exits to be used in an emergency?

Event coordinators should announce exits to be used in an emergency not more than 10 minutes prior to the start of the event. This timing is crucial because it allows attendees to be aware of their nearest exits without overwhelming them with information too far in advance, which could lead to forgetfulness or confusion when an actual emergency occurs.

By announcing the exits close to the event's commencement, attendees can effectively incorporate this important safety information into their immediate situational awareness, ensuring that they know how to exit the venue quickly and efficiently if necessary. This practice not only enhances safety but also encourages a proactive mindset among attendees regarding their personal safety and evacuation routes during the event.
