The purpose of this study is to induce improvement of fire safety performance of the existing buildings and suggest an improved system to enhance its effectiveness.

To do this, we proposed the method of management inspection and minimizing the possible damages of large-scale fires caused by several reasons, such as the usage characteristics of existing buildings, statistics of fire outbreaks, fire-related construction characteristics, etc. We also suggest the inspection of methods supporting the cost of reinforcing fire safety performance for buildings that are likely to cause large-scale casualties in case of a fire accident, and ways to review relevant laws such as the principle of confidence protection pursuant to retroactive application, and prepare the system to improve receptiveness by forming a public consensus.
