Abstract: In a theater venue that hosts about 40 million people a year, safety accidents are a non-negligible risk. Accidents can be very dangerous when there is an unrestricted crowd in a limited place. In 2006, dozens of people were crushed to death in the Sangju outdoor concert hall. As a result, the National Emergency Management Agency produced a safety management manual for the venue in 2007. The manual intended to lay out safety management rules for performances and events administered by local governments throughout the country. However, the guidelines were not implemented as they were not turned into legislation.
