Through the preliminary analysis of the characteristics of wooden cultural properties in the event of a fire, we seek to find vulnerabilities and improve fire detection technology and fire response technology. As a result of the fire simulation for the Daeungjeon Hall of Bulguksa Temple, the spread of the fire spread to the entire ceiling at 100,000, and a rapid fire spread around the corners. When the area in a specific fire propagation path was treated with fire protection material, the fire spread rate was 3 times slower.
