As the physical strategy for fire safety, this study demonstrated the needs to strengthen the legal punishment system, enforce thorough inspection of fire safety facilities and prevent illegal building extension. The economic strategy for reducing fire vulnerabilities includes the increase in personnel for disaster management. The social strategy focuses on improving risk management communication and preparing a practical alternative for disaster prevention by surveying and analyzing the disaster vulnerable. As for the environmental strategy, it proposes the resolutions of safety negligence, ostrich policy, and lax administrative regulations.
