Unpredictability is a part of life. Back in 1883, when a fire broke out in Victoria Hall, no one had ever predicted its possibility and hence, the lack of safety measures resulted in a loss of over 180 lives. Over time, the need to install adequate escape measures in buildings became evident, and today, nearly every building is expected to include measures for escape during contingencies. Pushbars were bred out of a dire necessity to find a simple means of unlocking during an emergency.
