An unplanned and unannounced evacuation event (Scenario 1) at a Cultural Centre observed 73% of its approximate 1730 occupants (41% capacity) evacuate using the main entranceway, despite, code-compliant exit signs, onsite personnel providing instructions and physical barriers meant to prevent the overuse of the main entrance. The remaining population evacuated using the 11 alternative ground floor exits, with no apparent preference of trend. As a result of the unplanned evacuation event, two planned annual drills were used to investigate factors that effected evacuations of Cultural Centres. These unannounced evacuation drills were conducted and held one year apart (Scenarios 2 and 3). The final drill (Scenario 3) was used to evaluate improved evacuation strategies and staff trainings, implemented by building management after the first two evacuation events.
