In relation to the introduction of a performance accreditation system for fire dampers, existing domestic fire damper performance was evaluated with respect to related regulations and the system operation required were considered. From the performance evaluation, it was judged that manufacturer efforts to improve the structure of fire dampers are necessary to improve performance and the relevant regulations must be supplemented. Strategies to implement new regulations may include evaluation of the heat-detecting fire dampers and introducing novel equipment for fire-fighting.

Building regulations in recent times require that fire dampers be automatically closed when detecting smoke or flame in the event of a fire. However, they may be vulnerable to fire themselves because they contain combustibles, such as motors. Therefore, the optimal installation locations of fire dampers for securing fire safety performance were selected through performance verifications in this study. Thus, it was found that fire dampers installed in contact with the fire compartment wall surfaces would be advantageous for securing the required fire safety performance.
