 Abstract
Recently, Since buildings are bigger and higher, the damage of human life can be increased by fire flame and smoke in fire. Smoke control system is necessary to decrease this damage. Therefore, Air supply pressurization smoke control system is applied to vestibule of escape stairway. NFSC requires pressure differential of 40 Pa~60 Pa, but pressure differential is over 60 Pa in the field. It is known that the cause of this over pressure differential is much leakage of damper. Over pressure differential can bad effect to escaper by pressurizing the door. Analyze the real leakage of damper by testing for identifying this problems. The result of testing, leakage is . It is necessary to limit the leakage of dampers for safe of escapers.
